OPTIMAL MIXTURE DESIGN OF HIGH PERFORMANCE SELF-COMPACTING CONCRETE

摘要：

This paper investigates the reasonable mix design parameters for SCC mixtures such as aggregate content,mineral admixture content and water/cement ratio,based on experimental study of workability and mechanical properties of self-compacting concrete(SCC)with strength grades from 30 to 60 MPa.The results indicate that the volume of course aggregate should be less than 33％ and fine aggregate should be between 47％ and 51 ％,the replacement of cement with fly ash can be 30％ to 40％ and the water-to-cementitious materials ratios should be less than 0.4.A modified calculation method is proposed,by which the content of each component of SCC mixtures can be determined easily.
