Concrete Additives

Overview of concrete additives

Concrete additives also referred to as concrete admixtures, refer to the material added to improve and adjust the performance of concrete. Concrete admixtures are chemical additives or mineral additives added during concrete mixing to enhance specific properties of the fresh or hardened concrete, such as workability, durability, or early and final strength. They can either be liquid or powdered additives. The amount of concrete admixture is generally not more than 5% of the cement quality. Because concrete admixture can improve the performance of concrete effectively, and has good economic benefit. It has been widely used in many countries and has become an indispensable material in concrete.

Classifications of concrete additives 

1. Additives to improve the variable performance of concrete mixing. Including a variety of water-reducing agents, air-entraining agents and pumping agents. 

2. Adjust the concrete setting time, hardening performance admixture. Including retarding agent, early strength agent and accelerating agent. 

3. Additives to improve the durability of concrete. Including air entrainment agent, waterproof agent and rust inhibitor. 

4. Additives for improving other properties of concrete. Including aerating agent, expansion agent, colorant, antifreeze, waterproof agent and pumping agent .

Uses of concrete additives

1. Can reduce the water consumption of concrete. Or you can increase the fluidity of concrete without increasing the amount of water used.

2. You can adjust the setting time of concrete.

3. Reduce concrete bleeding and segregation. Improved workability and water panning resistance.

4. Slump loss can be reduced. Increase permeability of pumped concrete.

5. It reduces shrinkage. The addition of an expansion agent can also compensate for shrinkage.

6. Delay the initial hydration heat of concrete. Reduce the temperature rise speed of mass concrete and reduce the occurrence of cracks.

7. Improve the early strength of concrete. Prevents freezing at negative temperature.

8. Improve strength, increase frost resistance, permeability resistance, wear resistance, corrosion resistance.

9. Control alkali-aggregate reaction. Prevent steel corrosion, reduce chloride ion diffusion.

10. Make concrete with other special properties.

11. Reduce the viscosity coefficient of concrete.

  • Waterproof agent
    Gypsum waterproofing agent is a technology that involves the development of gypsum to help achieve watertight concrete structures. TRUNNANO Gypsum waterproofing technology is available as a waterproof for gypsum concrete, or an integral admixture for concrete, for use in both above and below grade applications.
  • Concrete superplasticizer
    Efficient polycarboxylic acid Superplasticizers transform the hard and low slump concrete into flowing, toppable and easy-to-place. They improve machinability, speed up surface treatment, increase strength, save cement and help reduce shrinkage and thermal cracking.
  • Concrete Crack Reducing Admixture
    Using the right admixtures (or synergistic mixtures) to prevent or reduce the effects of cracking will extend the service life of concrete and lead to better performance. Using the filters below, you can identify the type of crack and better understand the solution based on the crack type.
  • Polyvinyl Alcohol Fiber PVA Fiber for Concrete
    The main characteristics of PVA fiber are high strength, high modulus, low elongation, abrasion resistance, acid and alkali resistance, good weather resistance. It is good affinity and bonding with cement, gypsum and other substrates. It is non-toxic and pollution-free. It does not harm human skin and is harmless to human body. It is one of the new generation of high-tech green building materials.
  • Microsilica Fume
    Micro-silica is finely processed from silicon dioxide (SiO2), also known as quartz, through crushing, purification, grinding, grading and other processes. It has high purity, white color, and reasonable particle size distribution. It has unique properties and a wide range of uses.
  • High temperature resistant aerogel felt
    Using high temperature resistant ceramic fiber composite technology, it is obtained by normal pressure or vacuum impregnation of sol, gel, solvent replacement and supercritical drying. The material has mild preparation conditions and simple process, and is easy to realize the preparation of large-size and special-shaped surface materials. It has the characteristics of light weight, high temperature resistance and low thermal conductivity.
  • TR01 425 grade white cement
    TR01 425 grade white cementTR01 425 white cement is a green and environmentally friendly product.
  • TR02 92whiteness 425 grade white cement
    TR02 425 white cement is a green and environmentally friendly product with high strength and no radioactivity in the early stage. The product has high whiteness, high strength, low alkalinity, good stability, and bright and bright color.
  • HPMC Hydroxypropyl Methyl Cellulose
    HPMC is a white or almost white powder, odorless, tasteless and non-toxic.This product can be dissolved in cold water to form a transparent viscous solution.
