Abstract

Reactive powder concrete is a result of developing process in concrete technology. It is a new type of 
composite material satisfying the increasing demands for high strength, high durability, offering superior 
ductility and workability   . In this experimental study, four mixtures were casted and testing ( slump test, 
absorption test, density test and compressive strength test). Four different ratio of polymer fibers were 
used (0  %,0.5% , 1% and 1.5%). The results of the slump test showed that the increasing of the polymer 
fibers ratio led to decrease the amount of slump. The results of the compression strength tests showed that 
the increasing of the polymer fibers ratio from  0% to 0.5%, 1% and 1.5%  led to decrease the 
compressive strength by (7.49% , 13.40% and 19.66% ) consequently at age 28days. The results of the 
absorption test showed that showed that the increasing of the polymer fibers ratio  from 0 % to 0.5%, 1% 
and 1.5%  led to increase  the absorption ratio    by ( 3.29% , 5.81% and 7.34 % ) consequently at age. 
The results of the density test showed the increasing of the polymer fibers ratio led to decrease the dry 
and wet density.
