20191122 ensp 0183 enspDifferent studies were conducted to investigate influence of aggregate content in concrete on compressive strength for a particular type of cement paste and it was found that a gradual decrease in compressive strength is associated with increasing volume of aggregate from 0 20 volume is measured as a percentage of total volume

Concrete in its basic nature have low tensile strength which causes cracking 4 Cracks in concrete generally interconnect flow paths and increase concrete permeability The increase in concrete permeability due to the progression of cracks allows more water or aggressive chemical ions to penetrate into the concrete

Recently it has been possible to incorporate relatively large volumes ranging up to 15 percent of steel glass and synthetic fibers in concrete With such a large volume of fibers in concrete some evidence presented in this paper indicates that the fibers may substantially increase the tensile strength
