Abstract
In building engineering research, sustainable materials are currently being researched and investigated. Recycled concrete aggregates, coal fly ash, crushed clay brick, and pervious paver block systems are some examples of sustainable research that are employed around the world. Fibre-reinforced concrete, which is made up of a mix of hydraulic cement, aggregates, water, and reinforcing fibres, has also been the subject of research. The growing demand for concrete in construction has resulted in a significant decline in natural river sand, creating environmental damage and an ecological imbalance.
The experimental investigation includes the substitution of fine aggregate, such as natural river sand. This fine aggregate is replaced by granulated blast furnace slag (GBFS). The blast furnace produces GBFS, which is a by-product of the iron and steel production process. It's a solid waste product that's thrown away. Because it is a waste product, GBFS may be utilised as a fine aggregate rather than being disposed of, which will considerably assist the environment, as solid waste management is a serious concern worldwide.
Part of this project is using GBFS to partially substitute fine aggregate in cement concrete. The percentage of natural river sand replaced with GBFS in the compression test ranged from 0% to 30%, 40%, and 50%. This variation was used to cast 12 cubes to test the compression strength of concrete. In quantities of 25%, 30%, and 35%, GBFS was utilised to replace natural river sand. Concrete properties such as compression, tension, and flexure were evaluated using this version. For the compression test, nine cubes were manufactured. 12 cylinders were made for the split tensile test, with tensile strengths of 0%, 25%, 30%, and 35%. To display the findings, tables and graphs are employed.
