Concrete Additives

  • Maltodextrin
    The addition of maltodextrin in building materials admixture can delay the heat of hydration and slow setting. Compared with other retarders, maltodextrin has a better effect on concrete and workability.
  • Triterpenoid Saponin Air entraining agent
    Triterpenoid saponin is a kind of glycosides extracted from tea seeds. It is a natural surfactant with good properties. It can be widely used in light industry, chemical industry, pesticides, beverages, aquaculture, textile, oil extraction, mining, building materials and highway construction and other fields.
  • Ascorbic Acid Vitamin C
    Ascorbic Acid is a white or slightly yellow crystals or powder, a little acid with the m.p. of 190℃-192℃. It is easily soluble in water, a little soluble in alcohol and uneasily soluble in Ether and chloroform and other organic solvent. In solid state it is stable in air. Its water solution is easily mutated when it meets with air.
  • Air Entraining Agent in Concrete
    Air-entraining agent refers to the ability to introduce a large number of evenly distributed tiny air bubbles in the concrete mixing process to reduce the bleeding and segregation of the concrete mixture, improve workability, and significantly improve the frost resistance and durability of hardened concrete admixtures.
  • Water-based Concrete Release Agent
    Concrete release agent TR-ARA is also called concrete isolation agent or release lubricant. It is a kind of material coated on the innewall of the formwork for lubrication and isolation, so that the concrete can be smoothly separated from the formwork whe
  • Alkali-free Concrete Additives Liquid Concrete Accelerator
    The dosage of concrete accelerator is 6-9% of the cement weight. Concrete accelerator can replace the same amount of water, and the actual mixing amount should be determined after adjustments are made according to the cement type, label and construction temperature.
  • Polyvinyl Acetate Ethylene VAE Copolymer Latex Powder
    Redispersible polymer powder VAE powder products are water-soluble redispersible powders, such as ethylene/vinyl acetate copolymers, vinyl acetate/ethylene tertiary carbonate copolymers, acrylic acid copolymers, etc., with polyvinyl alcohol as a protective colloid.
  • TR02 92whiteness 525 grade white cement
    TR02 525 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.
  • Aerogel Powder Particle
    Aerogel particles/powders are silica materials with three-dimensional network nanostructures.

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.
