Experimental Investigation on Physical Properties of Concrete Containing Polypropylene Fiber and Water-Borne Epoxy for Pavement

Cement concrete pavement accounts for a large proportion of the road network due to its excellent mechanical strength and durability. However, numerous microcracks are generated high brittleness concrete, which poses threat service life pavement. Currently, simultaneous addition fibers polymers is feasible approach resolving issues associated with concrete. This study explores properties mixtures containing different levels polypropylene water-borne epoxy. Additionally, fly ash also introduced mixtures. The tests performed include slump, compressive strength, flexural shrinkage, depth water penetration, abrasion. results indicate that epoxy, at all levels, contributed improving weak interfacial bonding between In addition, combined incorporation epoxy could improve durability utilization 0.1% 10% exhibiting best performance. Moreover, into abrasion resistance experienced slight reduction, while workability, drying shrinkage resistance, impermeability were improved. current findings appropriate beneficial application in pavement; however, spite superior impermeability, should be properly treated according actual engineering conditions.
