Abstract

Abstract: To compare the compressive strength of polymer coated conventional concrete to the compressive strength of novel polymer coated concrete with polypropylene fiber. Polypropylene fibers make up 3 % of the concrete mix, and the casted cubes are coated with polymer. This study's sample size is 36 (18 + 18 per group), and it was calculated by providing the hypothesis, significance level, and size, as well as estimating the values for evaluating the power test. The sample size was determined to be 18 after using clincalc to calculate an alpha value of 0.05 percent and a pretest power of 80 percent. The data were recorded and analyzed using the SPSS statistical analysis programme for 18 samples of plain conventional concrete and polypropylene fiber-added concrete. When the polymer coated plain conventional concrete was compared to the polymer coated plain conventional concrete, the mean significant differences of p = 0.001 were obtained using SPSS-V26 software. The compressive strength of polymer coated plain conventional concrete with a 3 % of polypropylene fiber volume fraction is much higher than that of polymer coated plain conventional concrete, according to the results of this investigation.
