摘要
综述了国内外利用废旧橡胶胶粉对砂浆混凝土改性的研究进展和研究前景。研究表明,在水泥砂浆混凝土中掺加废橡胶胶粉可以有效改善混凝土的收缩性能,提高其韧性、抗冲击性能、抗疲劳性能、抗冻性能,但同时混凝土的强度和弹性模量也会显著下降;而通过对胶粉进行表面改性后,可以有效改善其对强度的影响。该研究将有望应用到公路路面混凝土材料上。
This paper presents an overview of the research published focusing on the use of waste tire rubber crumb in mortar and concrete. It indicates that tire rubber crumb can improve some properties of concrete such as shrinkage, toughness, and impact resistance, freezing and thawing resistance, while the compressive strength and modulus of elasticity are decreased significantly. Studies indicated that if the tire rubber particles have given a pretreatment, then better and improved bonding may develop with the surrounding matrix and that may result in higher compressive strength and it could be applied to concrete pavement.
