Improvement of Compressive Strength of M30 Grade of Concrete by Novel Hypo Sludge with Addition of Sikacrete and Comparison of Compressive Strength of Conventional Concrete

Kakarla Ajay and Lakshmi Thangasamy

Abstract

The use of novel hypo sludge as a partial replacement for cement is examined in this research since it is crucial to the development of affordable building materials. To ascertain the ideal novel hypo sludge and sikacrete mix proportions for achieving the specified mechanical characteristics in concrete. Novel hypo sludge is used in concrete in place of cement with the addition of sikacrete as much as 30% when superplasticizers are employed, as well as when they are not utilized. In 28 days, the compressive strength was calculated. Comparatively to conventional concrete, which had a mean compressive strength of 33.50 N/mm2, novel hypo sludge-added concrete had a mean compressive strength of 36.60 N/mm2. Conventional concrete was casted with M30 mix design for 18 cubes of size 150 mm x 150 mm x 150 mm. In comparison to conventional concrete, which had a mean compressive strength of 33.50 N/mm2, concrete that has novel hypo sludge added at a 30% addition had a mean compressive strength of 36.60 N/mm2. From the statistical analysis the significant value is calculated as p value = 0.000, (p < 0.05), two-tailed and is considered as statistically significant in the accuracy rate with comparison of both novel hypo sludge and conventional concrete. Group statistics for a sample group of 30% of hypo sludge concrete mean (33.5050, 36.6000), standard deviation (1.08475, 0.96290) and standard error is (0.25568, 0.22696). The addition of hypo sludge (paper pulp) and sikacrete to cement can greatly enhance the performance of hypo sludge concrete when put through the compressive strength test.
