大体积混凝土生产与浇筑施工质量控制

Quality Control of Mass Concrete Production and Pouring Construction

大体积混凝土质量控制的重点是混凝土配合比设计与混凝土浇筑后的充分保温(根据当时环境温度)、保湿养护。围绕大体积混凝土原材料、配合比确定,使矿粉、粉煤灰、人工砂及聚羧酸高性能减水剂在大体积混凝土中得到良好组合应用。同时,针对大体积混凝土生产及浇筑施工提出有效控制措施。

The key points of mass concrete quality control are concrete mix proportion design and sufficient heat preservation(according to the environmental temperature at that time)and moisture conservation after concrete pouring.In this paper,based on the determination of raw materials and mix proportion of mass concrete,mineral powder,fly ash,artificial sand and polycarboxylic acid highperformance water reducer are well combined and applied in mass concrete.At the same time,effective control measures are put forward for mass concrete production and pouring construction.
