摘　　要：通过在混凝土中掺入不大于15%的硅粉,对配制C50高性能混凝土的配合比进行了试验,研究了掺入比例不同硅粉对混凝土的工作性能,以及不同龄期混凝土抗压强度的影响。试验表明:随着硅粉掺量的增加,混凝土拌合物坍落度先小幅增大后较大幅度减小,其拐点掺量是6%;而混凝土抗压强度最大值是56.1 MPa,其峰值出现在硅粉掺量15%时。找出了不同使用情况下硅粉的最优掺量,建立了回归方程,确定了掺硅粉高性能混凝土的最优配合比。Through the incorporation of not more than 15% silicon powder into concrete,test proportion of mixture of C50 high perfor- mance concrete, study the effect on the work performance and compressive strength of concrete at different ages by incorporating different proportions of silicon powder.Experiments show that： with the increase of content of silicon powder,the slump ratio of concrete mixture varies from greatly reducing to slightly increasing, the volume of inflection point is 6% ; While the compressive strength of concrete the maximum value is mpa with the peak at silicon powder content 9%.find out the optimum dosage of silicon powder under different circum- stances, establish the regression equation, confirm the optimum proportion of mixture of high performance concrete with silicon powder.
