摘　　要：为探究高炉矿渣粉对混凝土性能的影响规律,优选不同高炉矿渣粉掺量,开展混凝土的和易性能、力学性能、抗冲磨性能、抗冻性能及热学性能试验研究,结果表明:矿渣粉的掺入可以改善混凝土的和易性能;试验掺量下,矿渣粉掺量越大,混凝土后期抗压强度越高,抗冲磨强度也越高,掺入35%矿渣粉可使得混凝土的抗冲磨强度提升2.65%,同时磨损率降低6.51%;矿渣粉对混凝土抗冻性能的改善效果显著,掺35%矿渣粉可以将混凝土的抗冻等级提升至F400以上。测定了掺35%矿渣粉混凝土的热学参数、自生体积变形,以便为高炉矿渣粉的应用提供技术参考。Different dosages of blast furnace slag powder are selected for experimental research on workability,mechanical properties,abrasion resistance,frost resistance,and thermal properties of concrete.The effort is to explore the influence laws of blast furnace slag powder on concrete performance.The results show that the addition of slag powder can improve the workability of concrete.Under the experimental dosage,a larger amount of slag powder is accompanied by higher compressive strength and abrasion resistance of concrete in the later stage;the addition of 35%slag powder can increase the abrasion resistance of concrete by 2.65%while reducing the wear rate by 6.51%.The slag powder can significantly improve the frost resistance of concrete,and the addition of 35%slag powder can raise the frost resistance level of concrete to above F400.The thermal parameters and autogenous volume deformation of concrete mixed with 35%slag powder are measured to provide a technical reference for the application of blast furnace slag powder.
