摘要
本文研究了四种不同集料对不同强度等级混凝土的强度和断裂性能的影响 ,发现在高强混凝土中 ,集料的作用得到充分发挥 ,其对混凝土力学性能的影响更加显著。在配制高强混凝土时 ,通过选择高强低脆的岩石集料 ,能够大幅度降低混凝土的脆性。
? In this research,the influence of aggregate type on the mechanicl properties of high performance concrete was studied.The testing result shows that the aggregate plays an importance role in the high strength concrete,especial for the mechanical performance of concrete.It is suggested that the high strength concrete with lower brittleness can be made by selecting high strength aggregate with low brittleness. 〔
