crushed quartz meaning in Chinese

碎石英石

Depending on the densified system containing homogeneously arrayed ultra - fine particles ( dsp ) and the basic principles of reactive powder concrete ( rpc ) adopted by foreign researchers specialized in building materials , considering the characteristics of ultra - fine addition which can improve the workability and micro - structure of cement based materials and enhance the cementitious materials " packing density , we added blast slag silica fume crushed quartz superplasticizer and steel fiber into portland cement to produce the rpc by normal technology methods
本文以活性粉末混凝土( reactivepowderconcrete ，简称rpc )的基本配制原理为基础，结合近几年来人们对高性能混凝土研究所提出的要求，选择适合本地实情的材料，在传统rpc的配制基础上，掺入矿渣组分，配制出了抗压强度达135mpa的活性粉末混凝土材料。本文对掺矿渣rpc的配制技术及其相关的性能作了系统的研究。
