橡胶混凝土的力学性能试验

依据对废旧轮胎橡胶粉碎料作为添加成分取代部分细骨料的混凝土的力学性能进行了试验.制备了多组不同橡胶粒径和掺量的橡胶混凝土试件;试件采用的橡胶分别为胶粉和胶粒,掺量为细骨料体积的0,20%,40%,60%,80%和100%,以考查橡胶粒径和掺量变化对力学性能的影响.结果表明:橡胶混凝土的立方体抗压强度、劈裂抗拉强度、抗折强度等均随橡胶掺量的增加而降低,具有密度小、韧性好、抗裂性能强、变形能力大等传统混凝土难以企及的卓越性能.

Experiment on Mechanical Properties of Crumb Rubber Concrete

The mechanical properties of concrete with scrapped rubber tyre crumb replacing part of the fine aggregates were investigated.The testing method of mechanical properties was executed according to GB/T 50081-2002 standard for test method of mechanical properties on ordinary concrete.Many groups of crumb rubber concrete specimens were manufactured in different kinds of size and amount of rubber chips.The powder rubber and crumb rubber were mixed into C35 plain concrete,by the volume rations of 0,20%,40%,60%,8...
