橡胶改性水泥混凝土(砂浆)的研究综述

Overview of research on crumb rubber in mortar and concrete

综述了国内外利用废旧橡胶粉对混凝土(砂浆)改性的研究进展。有文献表明:与普通混凝土相比,橡胶改性水泥混凝土具有轻质及耐久性能、韧性和延性、抗冲击性能、抗爆裂性能、隔声和隔热性能好等特点。但是,目前橡胶粉-混凝土复合材料的研究仍存在一些问题。

The research publish focusing on the use of waste tire rubber crumb in mortar and concrete are presented.Some documents indicate that tire rubber crumb can improve a few properties of concrete, such as light weight, durability, toughness and ductility, impact resistance, explosive spalling resistance, sound insulation and heat insulation, and ere.But,now the research about the crumb rubber and concrete composite material still have some drfficulties.
