本文立足混凝土搅拌站原材料现状,通过选用搅拌站中品质较好的常规原材料,用优质外加剂来达到降低水灰比、提高强度及和易性的目的。通过双掺粉煤灰和矿渣粉,发挥其填充和活性效应,并通过掺加高性能的聚羧酸外加剂控制骨料品质,最终配制出强度等级达到设计要求的C80混凝土。 Based on the status quo of raw materials for concrete mixing plant, this paper aims to reduce the ratio of water to cement and improve the strength and workability by selecting the best quality raw materials in the mixing plant and using high quality admixture. Through the double mixed fly ash and slag powder, to play its role in filling and activity, and by adding high-performance polycarboxylic acid additive to control the aggregate quality, the final preparation of the strength level to meet the design requirements of C80 concrete.
