Abstract

Recycled solid wastes like rubber are one of the issues that impose a significant environmental challenge 
as a result of the rapid population growth. The reactive powder concrete is experimentally studied  with 
rubber tire waste to replace some of the fine aggregate. In this study, four mixtures were casted and test 
(slump, absorption, density and compressive strength test). Four different ratio of rubber waste (0 % ,5%, 
10% and 15%). The results of the slump test showed that the increase was used rubber tires wastes led to 
increase the slump of the mixture. This increase is due to the fact that the water covers the rubber 
particles, which in turn leads to reduction in friction between the components of the concrete mix. The 
results of the compression strength tests showed that.  the increase of the rubber tires wastes ratio from 
0% to 5% to 10% ,15% led to decrease the compressive strength by 13.02%, 36.56% and 37.87% 
respectively at age 28days. The results of the absorption test showed that the increase of the rubber tires 
wastes ratio from 0 to 5% to 10% to15% led to increase the absorption ratio by 7.91%, 11.76% and 
13.79% respectively age 28days. results of the absorption test showed that the increase of the rubber tires 
wastes ratio from 0 to 5% to 10% to15% led to increase the absorption ratio by 7.91%, 11.76% and 
13.79% respectively age 28days.
