摘　　要：钢渣微粉既是活性掺合料,又是矿物增稠剂,掺钢渣微粉的干粉砂浆,在复合外加剂的作用下,显示了优异的性能,不仅具有良好的工作性稠度大、分层度小、保水性能好、良好的力学性能(包括后期强度持续增长),而且还具有抗折强度高、低收缩、微膨胀和耐久性好等特点。Micro-powder of steel slag is both active admixture and mineral thickener. Under the action of composite addition agent, dry mortar with micro-powder of steel slag has excellent properties. It not only has good workability (large thickness, small delamination and good moisture retention), good mechanical property including late strength increasing continuously, but also has high flexure strength, low shrinkage, low expansion and good durability.
