摘　　要：通过在砌筑水泥中添加一定比例的赤泥和磷矿渣,研究赤泥和磷矿渣含量对混凝土抗压强度的影响。试验结果显示,加入赤泥会影响混凝土抗压强度,随着赤泥掺量的增加,其抗压强度减小;加入磷矿渣不会明显降低掺合料混凝土强度,甚至会增强混凝土强度,当添加磷矿渣比例为10%时,掺合料混凝土压缩强度为39.3 MPa,强度增加4.8%。This study investigates the effect of red mud and phosphate slag content on the compressive strength of concrete by adding certain proportions of red mud and phosphate slag to masonry cement.The experimental results show that adding red mud reduces the compressive strength of the concrete,and as the amount of red mud increases,the compressive strength decreases.However,adding phosphate slag does not significantly reduce the strength of the blended concrete,and may even enhance the strength.When the phosphate slag content reaches 10%,the compressive strength of the blended concrete is 39.3 MPa,with a 4.8%increase in strength.
