Analyzing the mechanical properties of green concrete by using GGBS and glass fibre for the sustainable development.

The Concrete has played a significant role in the building industry for many decades. Cement, fine aggregate, and coarse aggregate are all used in the production of concrete. Cement isa binding materialin concrete, and the use of this cementing material emits more CO2. Cement is partly substituted with industrial waste materials such as fly ash (FACF) and ground granulated blast furnace slag (GGBS), which has pozzolanic properties, to minimise carbon emissions. The aim of this study is to determine the compression, tensile, and flexural strength of standard concrete when fly ash and GGBS are partially replaced in cement in three proportions. The optimised mix was investigated with the addition of 0.5 percent glass fibres to cementitious material based on the proposed mixes. The concrete's output was measured using cast specimens that were examined for 7, 28, 56, and 90 days. Finally, in testing, 25% of GGBS and fly ash produced the best results. [ABSTRACT FROM AUTHOR]
