This paper outlines an experimental study that measures the effects of polymer fiber on proprieties of concrete. However, polymer fiber may serve as a superplasticizer admixture which may result to concrete’s lower rate of water absorption, high-range water reducer, greater strength and excellent in elasticity. Hence, an experimental investigation was conducted to determine the optimum dosage for the admixtures and to study the effect of over dosage of the mentioned admixtures. This elastic property of the polymer fiber reinforced in cement-concrete mix may produce better earthquake resistance of the building or structure as it deflects for a while as the load is applied and then returns to its original position as the load is removed. The experiments made were concrete with polymer fiber (polyvinyl alcohol, polyvinyl acetate) as the experimental group and a standard concrete mix being the control group. Polymer fiber used has been dissolved in water with five different proportions ranging from 2% to 10% with respect to cement’s percent by weight in kg. This specimen is molded in a cylinder with constant volume of cement, sand and gravel at 1:2:4 mix proportion of class “A”. The specimens formed were cured and tested to compressive strength on the 7th, 14th and 28th days after curing. Results prove that concrete mix having polymer fiber gave greater strength results than the standard mix.
