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.
