摘要
研究了石粉与矿渣粉复掺对混凝土拌合物工作性能和抗压强度的影响,并对其孔结构和水化产物进行了分析。结果表明,石粉的掺入,改变了混凝土水化产物,提高了其致密性;适当的复掺比例可以在有效保持混凝土抗压强度的基础上,明显改善其工作性能和孔结构;复掺料等量替代40%的水泥时,石粉和矿渣复掺的最佳比例约为2/3。
The workability and compressive strength of concrete mixed with limestone powder and slag were studied,and the pore structure and hydrates of concrete were researched.The results showed that the hydrates changed and the compactness increased with mixing the limestone powders.If the ratio of admixture was appropriate,the workability and pore structure of concrete were improved obviously,while the compressive strength decreased little.When 40% of the cement was replaced by admixture,the best ratio of limestone powder/slag was about 2/3.
