Abstract

Common place one important building material used all throughout the world is Portland cement. Aside from the combustion of fossil fuels and deforestation, the cement production sector is one of the biggest emitters of carbon dioxide. The atmospheric release of greenhouse gases, such CO₂, is the primary cause of global warming. Approximately 65% of global warming is attributed to greenhouse gases, such as CO₂. The worldwide cement sector is responsible for around 7% of greenhouse gas emissions into the environment. The development of substitute binders for concrete is necessary to mitigate the environmental impacts of Portland cement. Making concrete by partially substituting Metakaolin for cement is one way to improve the material’s early strength, durability, impermeability, and resistance to chemicals, while also having an ecologically favorable effect. Within this, project, the concrete contains additional components like Metakaolin. Experimental research uses concrete with a compressive strength of 57 MPa. Strengths of flexural, compressive and tensile are the mechanical attributes that are compared with modified concrete. Metakaolin was used in this study to partially substitute cement at percentages of 0%, 5%, 10%, 15%, and 20%. Concrete was used to produce the mix design of grade M50. Concrete’s split tensile, flexural, and compressive strengths were all attained with a 15% Metakaolin addition. According to earlier studies, the impact of blended Metakaolin on cement’s consistency, setting time, and soundness stays within acceptable bounds according to various standards. Due to its more lasting and less expensive manufacture of Metakaolin, it also addresses ecological and environmental issues.
