摘要
主要对人工砂在商品混凝土中的应用进行了研究,探讨了人工砂对混凝土工作性能、泵送性能及抗压强度的影响及经济效益分析,试验结果及工程应用表明,使用人工砂代替河砂配制的混凝土具有良好的工作性能及泵送性能,能配制C45及以下强度的混凝土。
This article mainly investigated the application of artificial sand in commercial concrete,explored artificial sand influence on the work performance,the pump performance and the compressive strength of concrete and economic benefit analysis.Test results and engineering application showed that using artificial sand instead of river sand in concrete has good work performance and pumping performance,to formulate concrete of the C45 and its following strength grade.
