An Experimental Study on Compressive Strength of Conventional Concrete Using 5% of Novel E-waste as a Partial Replacement of Coarse Aggregate in Comparing with Conventional Concrete

Balasundaram Gokul and Samuel Simron Rajkumar Johnpeter

Abstract

The primary study is to evaluate the differences between conventional concrete and M30 grade concrete with 5% novel E-waste as a replacement. Novel E-waste 20 mm, superplasticizer, cement (53 grade PPC), fine aggregate (sieve size 4.75 mm), coarse aggregate (sieve size 20 mm), and water. There are 2 groups that were considered. Group-1 (control group/conventional concrete) and group-2 (experimental group/Novel E-waste concrete). The first group has 18 samples, and the second group has 18 samples, Total samples of N = 29. G-power of 0.8 with alpha and beta qualities of 0.05, and 0.2 with a confidence interval (CI) of 95% have been carried out, with independent sample t-test value (p < 0.05). According to Analysis of Variance using SPSS (Statistical Package for the Social Sciences) software, it is clearly identified that the compressive strength of conventional concrete is 32.08 N/mm2. The compressive strength of novel E-waste concrete is 31.6 N/mm2. There is a significant difference and the significance value of 0.000 (p < 0.05) and also standard deviations are 8.7512 and 7.0012, respectively. The novel E-waste concrete with the superplasticizer has less compressive strength when compared to the normal concrete.
