Polycarboxylic acid water reducing agent has the following roles: 1, increase mobility in the amount of water and cement dosage is unchanged, the slump of the concrete can be increased by 100 to 200mm, significantly improving the fluidity of concrete, and does not affect the strength of concrete. Pumping concrete or other large mobility concrete need to be mixed with high-efficiency water reducing agent. 2, improve the strength of concrete in maintaining the mobility and cement consumption remains unchanged under the conditions, can reduce the amount of mixing water 10% to 15%, thereby reducing the water-cement ratio, so that the strength of concrete increased by 15% to 20%. Especially the early strength increase is more significant. Mixed with high-efficiency water reducing agent is the preparation of early strength, high strength, high performance concrete, one of the technical measures. 3, save cement in maintaining the fluidity and water-cement ratio under the same conditions, can be reduced in the mixing of water at the same time, reduce the amount of cement, that is, to maintain the strength of the concrete remains unchanged, can save the amount of cement 10% to 15%, and is conducive to reducing the cost of the project. 4, improve the durability of concrete As a result of water-reducing agent, significantly improve the pore structure of concrete, so that the compactness of concrete to improve the water permeability is reduced, thereby improving the impermeability, frost resistance, chemical corrosion and rust resistance and other capabilities. In addition, after mixing with water-reducing agent, it can also improve the water secretion and segregation phenomenon of concrete mix, slow down the setting time of concrete mix, and slow down the exothermic rate of cement hydration. Prevent cracks caused by internal and external temperature difference. I understand roughly these, if you want to be more specific you can contact the Gamma Lexor expert team.
