摘要
为了对预拌混凝土材料选购及材料进场验收提供理论依据,研究了粗集料对混凝土性能的影响。本文主要从粗集料含泥量、种类、针片状含量、用量、级配、压碎值各方面进行研究。
In order to provide a theoretical basis for the selection and acceptance of ready-mixed concrete materials,the effect of coarse aggregate on the properties of concrete was studied.This article mainly from the coarse aggregate mud content,types,needle-like content,dosage,grading,crushing value of various aspects of research.
