An Experimental Study on Compressive Strength of M30 Concrete Using Seashell Powder and Eggshell Powder as a Partial Replacement of Fine Aggregate in Comparison with Conventional Concrete

Pasupuleti Jaswanth and Ganesan Ramachandran

Abstract

The objective of the research is to compare seashell and eggshell based powder M30 concrete and conventional concrete on the compressive strength. In this study, a total of 18 samples were divided into two groups and prepared for data collection. One is made with ordinary concrete, and the other with seashells and eggshells-based powder M30 concrete. To perform the independent sample t-test, SPSS (Statistical Package for the Social Sciences) software, version 21, was used. The seashell and eggshell based powder M30 concrete sample has a mean compressive strength of 38.00 N/mm2, whereas the conventional concrete test sample has a mean characteristics compressive strength of 33.73 N/mm2. Independent samples t-test is performed to analyze the results. When a significant difference is found between the two groups in an independent sample t-test and the G-power is 80% and p = 0.053 (p > 0.05), the independent sample t-test is run for both groups is not statistically significant. The standard deviation is 2.90452, 5.81220, and the standard error is 0.68460, 1.36995, with the mean value being 33.7294, 36.8378. From the experimental study results, it could be found that the seashell and eggshell based powder M30 concrete has more compressive strength than traditional concrete.
