本文采用新疆的水泥、天然砂、机制砂为原材料,使用一般的技术手段研究在最佳级配曲线下的机制砂与天然砂混合,混合后的砂满足JGJ 52-2006《普通混凝土用砂、石质量及检验方法标准》。将得到的最佳级配的混合砂与一定数量的活性矿物掺合料、外加剂共同使用,进行大量配合比试验,取得试验数据,在混凝土抗压强度及耐久性方面得出一定的结论,制备的混凝土拥有良好的工作性和操作性,且各项技术指标满足GB 14902-2003《预拌混凝土》的要求。 In this paper, Xinjiang cement, natural sand, the mechanism of sand as raw materials, the use of general technical means to study the best grading curve of sand and natural sand mixing, the mixed sand to meet the JGJ 52-2006 “ordinary concrete sand, Stone quality and test methods standards. ” The best gradation of mixed sand and a certain number of active mineral admixtures and admixtures used in conjunction with a large number of mixing ratio test to obtain the test data in concrete compressive strength and durability reached some conclusions, Prepared concrete has good workability and operability, and the technical indicators to meet the GB 14902-2003 “ready-mixed concrete” requirements.
