摘要
为了施工时易于操作并且保证质量,混凝土拌和物应具有良好的工作性。系统分析了轻集料混凝土拌和物的易分层离析、坍落度损失大以及难以泵送等特点,介绍了对其工作性的评价方法,并从原材料选择、轻集料预处理、配合比设计以及其他方面出发提出了一系列改善其工作性及施工性能的技术途径。
In order to make the operation easily and ensure the quality in the construction ,the fresh concrete should have fine workability .in light of the behavior of easily segregating, great slump damage and poor pump performance of the lightweight aggregate concrete. We introduce the evaluation system of lightweight concrete workability and analyze a serious of technology methods on the factors of the choice of raw material, lightweight aggregate＇s handle in advance, the design of the mix proportion to improve the lightweight aggregate concrete＇s workability and construction performance.
