摘要
本文研究了高强混凝土及其集料的断裂特征和脆性,发现岩石集料的品种。特别是岩石的组织结构,不仅对岩石的断裂能和脆性有明显的影响,而且对高强混凝土的断裂能有影响.对其脆性有决定性作用。可以用选择高强混凝土集料岩石品种的方法,制作高强低脆的混凝土,达到大幅度降低高强混凝上脆性,提高预应力和普通高强钢筋混凝土结构使用的安全可靠性的目的.
In this paper,the brittleness and fracture characteristics of high-strength concrete and its ag- gregate stones were studied.The kinds of aggregate stones,in specially,their textu structures not only effected on fracture energy of stones and high-strength concrete,but also determinatively ef- fected on their brittleness.We may choice the sorts of aggregate stones in order to decrease the brit- tleness of high-strength concrete.The purpose of manufacturing the high-strength and low-brittle- ness concrete,is in order to increase safety and reliability in using of high-strength concrete to the prestress and reinforced concrete structures.
