Abstract

To minimize the environmental pollution and to utilize the wastes as suitable raw materials in concrete, hypo sludge is identified as the sustainable alternative material for the substitution of conventional construction materials. This paper is designed to investigate the inclusion of hypo sludge as supplementary cementitious material (SCM) and the influence of hypo sludge on the mechanical and durability of the concrete mix made with different cement replacement levelsand to investigate the influence of basalt fibre and Styrene-Butadiene rubber latex (SBR) on the strength and durability properties of hypo sludge concreteand to examine the flexural behaviour of optimized latex-modified basalt fibre reinforced hypo sludge concrete. The addition of basalt fiber by 0.3%, with 10% of SBR latex in hypo sludge concrete improved the mechanical, durability properties and flexural behaviour of concrete. © 2025 The Authors.

1. Introduction Concrete is the most versatile artificial construction material, extensively used for many sorts of activities (Regupathi et al. 2025). During the manufacturing of cement, it emits carbon dioxide (CO 2 ) (Which is around 7% of the total global CO 2 emissions) and other greenhouse gases, which causes many environmental and health hazards and has a negative impact on global warming.
