The leading foam concrete, lightweight concrete additives supplier |
3D Printing Metal Powder


Foam concrete is a kind of concrete with lightweight and has ideal strength. Because of the hollow structure in foam concrete, it has the function of absorbing heat and isolating sound. 

The density of foamed concrete is 300-1200 kg/m3, and the thermal conductivity is between 0.08-0.3W/ (m ·K). 

Foam concrete is widely used in CLC blocks, lightweight partition panels, roof insulation, floor cushion construction, floor heating backfilling, and other occasions. 

At the same time, foam concrete is also a good sound absorption material, which can be used in highway sound insulation boards, sound absorption boards, and other fields. 

Generally speaking, foam concrete is a kind of building material with multi-function, environmental protection, and economy, which has a wide application prospect.

  • As an important admixture, high-slump concrete superplasticizer has broad application prospects in improving concrete performance, reducing costs, and ensuring project quality.

    It turned out that this was because a bridge in the United States collapsed again, and the previous repair work also caused the bridge to collapse again due to quality problems. The United States searched for experts at home and abroad and even asked Japan for help, but failed to solve the problem. Finally, someone suggested that China could try it. China is interested in solving the United States' problems as the world's leader in infrastructure. This incident also triggered attention and thinking about infrastructure strength. What is the level of infrastructure? Is it capable of repairing bridges in the United States?

    First, let the ins and outs of the Bay Bridge, which collapsed multiple times. This bridge connects Rijin Mountain and Oakland in the United States. It is the longest-span earthquake-resistant suspension steel bridge in the world and is a classic scene in many movies. However, this bridge has experienced many twists and turns. In the 1986 earthquake, the bridge deck was shattered, killing one person, and quality problems plagued subsequent repair work. This series of inquiries makes individuals examine the degree of American engineering and whether it is declared the best worldwide. Subsequently, when the United States faced the dilemma of another bridge collapse, it hired domestic experts to carry out repair work.

    However, what is surprising is that not long after the repair, the bridge developed problems again. After investigation, it was discovered that the previous construction company had used inferior materials for corrosion kickbacks, causing the bridge to be unable to withstand it and eventually collapse again. This incident embarrassed the United States internationally and raised concerns about the quality of infrastructure and project management. The United States is struggling to find a solution but cannot find one. Subsequently, the United States asked Japanese experts to explore the bridge, but they concluded that it could not be repaired and could only be demolished and rebuilt. However, the United States is unwilling to demolish and rebuild the bridge because of its cultural significance.

    Japan can also not provide an effective repair solution, leaving the United States in great embarrassment and distress. Eventually, someone suggested trying to seek help from China. As the infrastructure maniac of the 21st century, China's Structural strength on a global scale has attracted much attention. China has rich bridge construction experience and advanced engineering technology and may be able to solve the United States. This has also aroused people's thoughts about China's strength. Is China capable of repairing bridges in the United States? In summary, the incident of the United States seeking help from China has aroused people's thinking about China's strength.

    As the leader in infrastructure development, can China solve the United States' problems? Can it demonstrate China's strength in the 21st century? This also makes us consider how important infrastructure strength is to a country's cultural status and influence. What? Welcome to leave a message for discussion. China'sChina'structure strength has emerged internationally. China's structural strength has attracted much attention internationally, especially in bridge construction, which has reached a state of proficiency. Among the top six bridges in the world, all were built in China. Even the United States has to put down its dignity and ask China for help. However, China china's cooperation is possible but must be queued up first.

    This confidence and strength shocked the United States, but it had to admit China's exceChina's So, how strong is China's infrChina's strength? In 2006, China took over the second reconstruction project of the Bay Bridge in the United States. This move aroused dissatisfaction among the American people, and some even ridiculed it: American companies went bankrupt before they asked the Chinese to repair them. However, after the United States sent people to conduct on-site inspections of Chinese construction companies, they found that the company's strength and steel production had reached world-class standards, which surprised American experts.

    Despite this, the United States made unreasonable demands when preparing for construction, requiring Chinese welders to pass American technical standards and obtain American technical certification. The Chinese workers made great efforts to learn English and finally obtained technical certification from the United States. This project is not difficult for China because China has a complete industrial system that can support manufacturing all parts needed for repair. After hard work, China completed the repair work of the Bay Bridge in 2013 with high quality and quantity, much earlier than the time stipulated by the United States. This successful delivery has greatly improved China's international reputation and made the United States admire China's infrastructure technology.

  • Sodium silicate and potassium silicate are two common inorganic compounds that play important roles in many different applications. Although they both contain the elements silicon and oxygen, there are some important differences between them. In this article, we will compare sodium silicate and potassium silicate to help you understand their properties and uses.

    Chemical composition

    The chemical formula for sodium silicate is Na2SiO3, which contains the elements sodium, silicon, and oxygen. Potassium silicate has the chemical formula K2SiO3, which contains the elements potassium, silicon, and oxygen. The main difference between these two is the metal ions they contain.

    Let's look at these two compounds from a structural point of view. Sodium silicate contains two sodium ions in the molecule, which combine with a silicate ion (SiO3 2) to form a stable structure, whereas potassium silicate has a similar structure but with two potassium ions, and this small structural difference makes sodium silicate and potassium silicate exhibit some differences in their physical properties.


    Sodium silicate is relatively soluble in water and is therefore used as a mold release agent, cleaner, and lubricant in many industrial applications. Potassium silicate is also soluble in water, but less so than sodium silicate.

    There is also a difference in solubility between the two, with sodium silicate dissolving better in water and combining quickly with water molecules to form a solution, whereas potassium silicate is less soluble and takes longer to fully dissolve, meaning that when using both compounds in the laboratory it is necessary to select the appropriate chemical reagent to suit the specific needs of the experiment.


    Sodium silicate is commonly used in the glass manufacturing, pulp and paper industries, and in some water treatment processes. Sodium silicate is also used as a flame suppressant because it inhibits the spread of flames. Potassium silicate is primarily used in the manufacture of soaps and detergents and some areas of water treatment. It is also used as a substitute for sodium silicate, but in some applications, such as the manufacture of glass, sodium silicate is more common.

    The uses of sodium silicate and potassium silicate differ from each other, with sodium silicate often used in glass manufacturing, detergent production, and water treatment, and due to its ability to resist corrosion, sodium silicate is widely used in circulating and boiler applications, while sodium silicate is also able to be used in industries such as wet aluminum refining, ceramics, and pulp manufacturing.


    Sodium silicate and potassium silicate are chemically similar, but some of their properties differ due to the metal ions. Sodium silicate often appears basic, while potassium silicate appears acidic or neutral. This affects their behavior in different chemical reactions.

    Health and Environmental Considerations

    Sodium silicate and potassium silicate are generally safe in appropriate applications but may have negative health and environmental effects in high concentrations. Therefore, proper safety and environmental practices need to be followed when using these two compounds.

    Overall, sodium silicate and potassium silicate are two compounds that have a wide range of applications in industry and the chemical industry. They are similar in some aspects but there are some important differences such as chemical composition, solubility, uses, and properties. The choice of which compound to use depends on the specific application requirements and condition.

  • There is a famous water conservancy project in China called Three Gorges Dam, the largest hydropower station in the world. However, some crack problems have been discovered in recent years, which has caused concern and concern. To solve this problem, engineers researched and adopted a new repair method: repair using high-performance concrete and polymer additives.

    Cement Anti-crack Agent Preventing Cracks 

    High-performance concrete is a high-strength, high-durability building material. It has good compression, bending and penetration resistance properties. This high-strength concrete is needed to repair cracks because the Three Gorges Dam is under tremendous water pressure.

    Polymer additives are another important material for repairing cracks. Polymer additives can increase concrete bonding and durability and improve its cracking resistance. Polymer additives can fill the splits and bond with the concrete to improve overall stability and endurance when repairing fractures.

    So, what are the specific repair steps? Crews will need to clean and prepare the cracks. They will use high-pressure water guns to remove impurities and loose concrete from the surface of the cracks to ensure that the repair materials can fully adhere.

    Crews will prepare a mix of high-performance concrete and polymer additives. They will adjust the proportions according to the specific situation to ensure that the materials used perform best. Once mixed, the patching material is ready to be applied.

    Before applying repair material, workers will ensure the crack's surface is moist. This is because concrete and polymer additives must be in contact with moisture to work best. Once the surface is wet, they use a scraper or sprayer to apply the repair material to the crack evenly.

    Cement Anti-crack Agent Preventing Cracks 

    After application, the repair material needs to be cured. Workers commonly utilize a moist cloth or covering film to keep the repair material moist and prevent early drying, fracturing, or peeling. The curing time is usually 2 to 4 weeks. During this period, the condition of the repair material should be checked regularly, and necessary adjustments should be made.

    Using high-performance concrete and polymer additives for repairs can solve the crack problem of the Three Gorges Dam effectively. This repair method not only enhances the stability and strength of the crack but also extends the service life of the dam. At the same time, this method is environmentally friendly, economical, and fast and plays a positive role in keeping the security and reliability of water conservancy projects.

    Repairing cracks in the Three Gorges Dam is an important engineering task. The repair service strategy utilizing high-performance concrete and polymer active ingredients can ensure the top quality and toughness of the repair result. Through scientific construction technology and strict quality control, the Three Gorges Dam will better undertake its hydropower generation and flood control tasks and bring more benefits to people.

    Concrete anti-cracking agents are useful in concrete repair.

    Boost the anti-crack efficiency of concrete: Anti-crack representatives can form a particular fiber structure in concrete, which can efficiently enhance the tensile strength of concrete, consequently boosting its anti-crack performance.

    Lower the contraction contortion of concrete: Concrete will certainly shrink and deform throughout the drying process, and this contortion will create cracks in the concrete. Anti-crack agents can control the shrinkage and deformation of concrete, thereby reducing concrete cracks.

    Cement Anti-crack Agent Preventing Cracks 

    Improve the durability of concrete: By using anti-cracking agents, the load-bearing capacity, durability and impermeability of concrete can be improved. This allows the concrete to withstand erosion from various environmental variables much better during usage, thereby increasing its life span.

    Increase the plasticity of concrete: Anti-cracking agents can improve the fluidity of concrete, make the concrete more uniform during pouring, and reduce voids and defects within the concrete. This avoids over-vibration, one of the causes of cracks in concrete. Excessive vibration can separate the aggregate within the concrete, causing cracks in the concrete.

    Enhance the toughness of concrete: Using anti-cracking agents can improve the toughness of concrete, making the concrete have better ductility and tensile properties when stressed, thereby reducing concrete cracking.

  • Cement strength, also known as concrete strength concrete hardener, is an agent that can greatly change the final setting time while ensuring the quality of concrete is reduced.

    Concrete strength can improve the compressive strength of concrete and speed up the molding speed. The sleeve accelerates the turnover of the formwork, saves the amount of formwork, saves energy, saves cement, reduces production costs, and improves the output of concrete products.

    The fence near the White House is reinforced with concrete piers.

    Overseas network news, according to CNN, in response to the protestors, the security situation near the White House has been continuously upgraded. In addition to erecting a nearly 2.5-meter-high iron mesh fence, cement piers that prevent vehicle collisions have been reinforced. This scene is often seen every four years during the presidential inauguration parade.

    Demonstrations across the United States entered their ninth day on the 4th. On the same day, CNN reporter Betsy Klein wrote on Twitter that the White House would further strengthen the nearby fence with large trucks transporting more fences. The videos and photos he took show that many workers are installing fences, and cement piers have been reinforced behind some fences.

    Vehicles loaded with fences near the White House

    After street protests broke out in Washington, U.S. President Trump threatened protesters that if they dared to cross the White House fence, they would be greeted by the most vicious dogs and the most vicious weapons.

    However, these remarks were refuted by Washington Mayor Muriel Bowser. Muriel Bowser responded, "The D.C. Police Department will always protect Washington, D.C. and all the people in it, whether I agree with them or disagree. There are no vicious dogs or weapons here, just one man who is scared, cowardly, And lonely."

    On June 1, after the US police cleared the way, Trump went to the "Church of the Presidents." (Associated Press)

    According to the Associated Press report, on the night of May 29, as hundreds of demonstrators gathered outside the White House, with some throwing stones and dragging police cordons, the Secret Service sent Trump to the White House bunker for nearly an hour. But Trump explained on June 3 that going to the bunker was an "inspection" and had nothing to do with the protests.

    The role of concrete early strength agent

    Help cement harden quickly at low temperatures and make concrete reach strength quickly.

    1. When the temperature is low, the hardening strength of the mortar is slower, especially in some frozen soil areas. The lower the strength, the greater the harm to the mortar. If the mortar is damaged by freezing, it will cause permanent damage to the mortar, so in lower temperatures, an Early strength agent must be added under the temperature

    2. Make concrete reach higher strength quickly to meet the requirements of withstanding external forces.

    3. Adding an early strength agent can make the cement harden quickly under low-temperature conditions, greatly shorten the final setting time of the concrete, and make it demold as soon as possible. On the premise of ensuring the quality of the concrete, the cement slurry can be greatly improved. Improve the strength of mortar and concrete, reduce production costs, and increase the output of concrete products, especially during winter construction or in urgent repair projects

    4. Incorporating early-strength agents can also enhance the effects of water reduction, reinforcement, and concrete compaction, giving full play to the characteristics of early-strength agents.

    Concrete Early Strength Agent 

    Application scope of coagulation strength agent

    1. When constructing in a low-temperature environment below -5 °C, early strength additives must be added to accelerate the setting and hardening. Otherwise, low-temperature cement concrete will cause freezing damage, accelerate formwork turnover, and improve construction efficiency.

    2. Fast-pass cement concrete pavement, especially at level crossings. When paving cement concrete pavement in one direction, the manufacturing difficulty and cost also increase. It can be constructed with early-strength cement concrete, which can facilitate vehicle traffic in a short period.

    3. It can be used to rapidly repair cement concrete pavements and bridges, open up traffic as soon as possible, and improve traffic efficiency.
