Application of Novel Hypo Sludge and Addition of Sikacrete to M25 Grade of Concrete and Comparison of Improved Flexural Strength with Conventional Concrete

Kakarla Ajay and Lakshmi Thangasamy

Abstract

Aim: This research examined the impacts of hypo sludge on concrete in an effort to increase its mechanical strength properties. To assess the economic and environmental benefits of using novel hypo sludge and Sikacrete in concrete mixes, such as reduced waste disposal costs and lower carbon footprint.
Method: Effect of Sikacrete addition and hypo sludge (Paper pulp) replacement in cement on flexural strength of concrete in comparison to conventional concrete grade M25.
Results: This experimental study used concrete of the M25 grade and a flexural strength test to examine the impacts of hypo sludge optimum level of 30% on the strength characteristics. The test findings reveal that hypo sludge infused concrete outperforms cement-only concrete in terms of performance. The mean flexural strength of the novel hypo sludge-added concrete was 14.96 N/mm2, whereas the conventional concrete’s value was 12.91 N/mm2. When comparing the accuracy rate of both novel hypo sludge and conventional concrete, the statistically significant value is computed as p-value = 0.000, (p < 0.05), two-tailed and is regarded as such. Standard deviation (0.66145, 0.76014), standard error of the mean (12.9111, 14.6611), and mean (0.15591, 0.17917). Conclusion: The addition of hypo sludge (Paper pulp) to cement and Sikacrete can consequently significantly improve the performance of high strength concrete.
