Abstract :

Polypropylene is a synthetic hydrocarbon polymer, the fiber of which is made using extrusion processes by hot drawing the material through a die. Its use enables reliable and effective utilization of intrinsic tensile and flexural strength of the material along with significant reduction of plastic shrinkage cracking and minimizing of thermal cracking. The fies are chemically inert, have hydrophobic surfaces, are very stable in the alkaline environment of concrete and resist plastic shrinkage cracking. Nevertheless, they also have some disadvantages including poor fire resistance, sensitivity to sunlight and oxygen, a low modulus of elasticity, and poor bonding with the concrete matrix. This study presents the information about the polypropylene fie for sustainable and economical concrete. Polypropylene fies can be used in concrete to improve its strength, aasion resistance and other durability factors.
