废橡胶改性再生混凝土材料性能研究进展
Research Progress on Material Properties of Recycled Aggregate Concrete Modified by Waste Rubber
摘要
Abstract
As a new type of engineering technology , waste rubber recycled aggregate concrete can solve the problems of the construction waste and waste tires , which is of great significance to protect the natural environment .In this paper , the research status of waste rubber recycled aggregate concrete at home and abroad is expounded in detail , the proportioning principles , technology , static and dynamic mechanical properties , durability and high temperature performance of waste rubber recycled aggregate concrete are introduced , and then next research is expected .The results show that in the case of constant replacement rate of recycled aggregate , the mechanical properties of waste rubber recycled aggregate concrete are gradually decreased with the increase of the rubber replacement rate , and its mechanical properties can be improved by adding some steel fiber , silicon powder or modified rubber; the steel fiber rubber recycled aggregate concrete has good fracture energy and fracture toughness; compared with recycled aggregate concrete , waste rubber recycled aggregate concrete possesses excellent performance of fatigue resistance and impact resistance;the chloride ion permeability resistance and frost thawing resistance of waste rubber recycled aggregate concrete are increased with the increase of the rubber particles , but decreased with the increase of rubber particle size; the corrosion resistance of waste rubber recycled aggregate concrete is improved by adding nano-materials or mixing rubber and ternary cementious system;the stiffness and bearing capacity of steel fiber rubber recycled aggregate concrete are weakened after high temperature , but its ductility is improved .关键词
