摘要
为确保商品混凝土成本,保证混凝土的耐久性,分别就人工砂和涂河砂代替混凝土中细骨料应用于商品混凝土的可行性,进行了筛分试验、水泥砂浆试配和混凝土中不同掺量试验,取得了良好的效果。
In order to reduce the cost and ensure the durability of ready mixed concrete the feasibilities of artificial and river sand used as fine aggregate in ready mixed concrete are discussed. Sieve experiment, trial mix of cement mortar and mix proportion tests are carried out, which received good effects.
