Research on Best Modifier and Proper Proportion for Rubber-particle Used in Rubberized Concrete for Road
摘要
Abstract
The paper carries out the research on mixing and surface modification of waste rubber-particle used in concrete pavement, analyzes its proper proportion and explores the best modifier and modifying process for it. The test studies show that rubber-particle for road is mixed appropriately in case of ＂low proportion＂, ＂high mesh＂, and ＂multiple mesh size distribution＂ with the proper proportion being 4 % and the best modifier being inorganic salt agent. When CaC12 is used as modifier with the quantity of 5 % by mass of rubber- particle, the strength of rubberized concrete can be increased by 14.0 % holding back a decline of its strength from 27.7 % to 17.5 % and leading to significant modifying result.关键词
