Flying ash chemical is a chemical agent used in concrete additives. Its role mainly includes the following aspects:
Improve concrete strength: Flying ash chelated agents can react with free lime in the fly ash to generate stable compounds, such as calcium silicate gel materials. This reaction can enhance the hardening process of concrete, promote the hydration reaction of the cement, and improve the strength and durability of the concrete.
Improvement of concrete work performance: Flying ash chelated agent can improve the liquidity and pumping of concrete, making it easier for construction and pouring. It can reduce the viscosity of concrete, improve liquidity, reduce internal friction, and make concrete easier to flow and fill in the template.
Reduce concrete contraction and cracking: Flying ash chelating agents can reduce the shrinkage of concrete, control the dry shrinkage and heat contraction of concrete, thereby reducing the risk of concrete cracking. It can form gel substances in concrete, fill pores, reduce water loss, and improve the stability and durability of concrete.
Improve anti -penetration performance: Flying ash chelated agents can fill the micro -pores and cracks in concrete to reduce the penetration of the penetration medium (such as water and gas). It can improve the density and density of concrete, improve resistance performance, reduce moisture transmission, and enhance the waterproof performance of concrete.
Promoting environmental protection and sustainable development: Flying ash chelated agents can effectively use industrial by -products to fly ash to reduce their negative impact on the environment. Through the role of chelating agent, fly ash can be stably solidified in concrete, improves the utilization of fly ash, reduces the demand for natural resources, and promotes sustainable development.
You need to choose the appropriate fly ash chelating agent according to the specific engineering requirements and the concrete formula, and put it into use in accordance with the suggestions and instructions of the manufacturer.
