| 摘 要： | 混凝土是由水泥砂浆填充粗集料孔隙形成的密实结构,粗集料构成了混凝土中的强度骨架,粗集料的强度、最大粒径、岩石类型以及在混凝土中的体积分数等都会对混凝土的各项性能产生不同程度的影响.对诸多文献中粗集料对混凝土强度、弹性模量、收缩和渗透性能的影响的研究成果进行了综述,为混凝土配合比的科学设计提供参考.

| Abstract: | Concrete can be considered as a matrix constituted of cement mortars filling in the voids of coarse aggregate.The coarse aggregate forms the framework of the concrete,most of its properties,e.g.its strength,maximum size,rock sort and its volume fraction in concrete are responded for the properties of concrete by varying degree.This paper reviewed the research works on effect of coarse aggregate on the strength,elastic modulus,shrinkage and permeability of concrete to comprehensively understand the effects c... |
