Abstract

<jats:title>Abstract</jats:title><jats:p>Concrete, a structural material in buildings is made of aggregate, which is a dense, chemically inert material, cement, and water. Concrete’s production, use, and environmental impact are complicated, influenced in part by the direct effects of infrastructure and buildings as well as CO<jats:sub>2</jats:sub> emissions. Cement, a key ingredient with its own negative social and environmental effects, is a significant part of what makes concrete. To reduce CO<jats:sub>2</jats:sub> emissions, it is important to substitute another material for cement. Slag is one of these alternative materials. It is a byproduct of steel factories that is produced in blast furnaces during the iron-ore separation process. The resulting granulated slag is further ground in a spinning ball mill creating a very fine powder known as GGBS. CaO, SiO<jats:sub>2</jats:sub>, Al<jats:sub>2</jats:sub>O<jats:sub>3</jats:sub>, and MgO are the primary components of blast furnace slag. These are minerals that are present in the majority of cementitious materials. The husk of the coconut fruit is used to make coconut fibre, one of the natural fibres that are widely available in tropical areas. Globally, 500 000 metric tonnes of coconut fibre is produced each year, primarily in Sri Lanka and India. Finding ways to make concrete, the most frequently used building material in the world, more stable and strong would undoubtedly be beneficial. The usage of coconut fibre to reinforce concrete has increased due to the quantity and accessibility of the material. The mix design for the study’s M30 grade concrete was carried out. The specimens were cast by partially substituting cement with GGBS in escalating weight percentages of 0 to 50, with the ideal replacement content being discovered. Later, coconut fibre was added to GGBS-based concrete in percentages ranging from 1 to 4 by weight. The specimens were cast, allowed to cure, and then tested at 7 and 28 days for compressive,.split tensile, and flexural strength. According to the findings, using 30% GGBS as a partial replacement for cement with 1% coconut fibre addition has resulted in high strength than control mix.</jats:p>
