La compatibilitat del material reductor d'aigua i de ciment

As a result, polycarboxylic acid water-reducing agent's saturation point fluctuates greatly, the water-reducing rate is different in size, and the slump loss is variable. Sometimes, concrete mixture bleeding, segregation, or slump loss is large, like "bean curd residue" without liquidity. The fineness and freshness of cement, the type and quantity of admixture in cement, mineral composition, especially the content of tricalcium aluminate, the type and quantity of gypsum, the carbon content and water demand of fly ash and other properties will affect the adaptability of water-reducing agent to cementitious materials.
