摘　　要：为研究砂含泥量对水泥混凝土强度的影响,分别在不同的水泥用量及所用砂含泥量下进行标准抗压强度试验,对比各种配合比下混凝土的强度。试验结果显示:混凝土用砂中含泥量对强度的影响远远超过水泥用量的影响,故在实际工程中必须严格控制混凝土用砂的含泥量。In order to study the influence of mud content of sand on the strength of cement concrete, standard compressive strength tests were carried out respectively with different cement amounts and mud contents of sand, and the strengths under various mix proportions were compared. The results show that the influence of mud content of sand on the strength overtakes that of cement amount, so the mud content should be strictly controlled in actual projects.
