摘　　要：主要对掺加石灰石粉的低强常态混凝土技术进行研究,对由3种不同细度的石灰石粉拌制而成的混凝土进行对比和分析,结合试验结果来看,在混凝土中掺加一定剂量的石灰石粉能够有效提高混凝土的流动性,但是混凝土的强度有所降低。通过对生产因素进行分析后可知,在满足混凝土强度要求的前提下,掺加石灰石粉能够有效提高混凝土的流动性,还可以降低混凝土的生产成本。The paper mainly studies the low-strength normal concrete technology with limestone powder,and compares and analyzes the concrete mixed with three different fineness of limestone powder.According to the test results,adding a certain amount of limestone powder into the concrete can effectively improve the fluidity ofthe concrete,but the strength of the concrete is reduced.After analyzing the production factors,it is found that adding limestone powder can effectively improve the fluidity of concrete and reduce the production cost of concrete on the premise ofmeeting the requirements of concrete strength.
