%X 研究燃煤炉渣粉掺量(外掺含量分别为胶凝材料的0%、5%、10%、15%、20%)对粉煤灰–炉渣混凝土物理力学性能的影响。试验结果表明：随着燃煤炉渣粉掺量的增加，混凝土抗压强度、劈裂抗拉强度、轴心抗压强度等呈现逐渐上升的趋势，从掺量和强度综合考虑，燃煤炉渣粉掺量为20%可以配制56 d抗压强度为37.19 MPa混凝土；混凝土的吸水率随着燃煤炉渣粉掺量的增大而增大，该研究对于燃煤炉渣粉在工程中的应用具有一定价值。<br />
Abstract
The effect of the content of coal-fired slag powder (0%, 5%, 10%, 15% and 20% of cementitious material respectively) on the physical and mechanical properties of fly ash-slag concrete was studied. The test results show that with the increase of the content of coal-fired slag powder, the compressive strength, splitting tensile strength and axial compressive strength of concrete show a gradual upward trend. Considering the content and strength, when the content of coal-fired slag powder is 20%, the concrete with 56 d compressive strength of 37.19 MPa can be prepared; the water absorption rate of concrete increases with the increase of the content of coal-fired slag powder. This study has certain value for the application of coal-fired slag powder in engineering.
