Experimental Investigation of High-Performance Concrete Using Metakaolin and Steel Fibers in Conventional Concrete

Abstract

Possibly the most extensively utilized building material worldwide is concrete. To address concerns about cost, energy, environmental protection, and resource conservation, the amount of mineral admixture added to cement has significantly increased as the concrete industry has grown. However, pressure has been applied to limit cement use through the use of supplemental materials due to environmental concerns about the harm caused by raw material extraction and carbon dioxide emissions during cement manufacturing. With the increase in demand for construction materials, there is a strong need to utilize alternative materials for sustainable development. The main objective of this investigation is to study the properties, such as compressive strength Metakaolin is used for the project is available in chemical factories. The proportion of cement substitutes by metakaolin and steel fibers has been substituted at 10%+5%, 20%+10%, 30%+15% and 40%+20% respectively. After testing, the cast specimens for 28days curing. The Mechanical and resilience characteristics of the specimens at various ages have been found out.
