Bleeding and segregation are mainly caused by the "over-mixing" of admixtures, which leads to poor adaptability between cement and admixtures. This situation is relatively common. Therefore, the most effective way is to reasonably reduce its dosage. While maintaining the same water-cement ratio or water-cement ratio, increase the water consumption appropriately and increase the total amount of cementitious materials accordingly to solve the bleeding and segregation phenomenon. However, the slump loss range needs to be reasonably controlled to facilitate construction. .
Secondly, due to the problems of cement itself, poor water retention leads to poor adaptability of cement and admixtures. To solve this phenomenon, you can appropriately increase the dosage of admixtures or use high-concentration water-reducing agents to increase the water-reducing rate, reduce the single water consumption of concrete, reduce the free water of the mixture, improve the water retention performance, and improve the adaptability of cement and admixtures. Purpose. </p
