Study of the Compressive Strength of Normal Concrete With Partial Replacement of Cement, Fine Aggregate & Coarse Aggregate

Abstract

The increased demand for conventional construction materials, as well as the need to provide long-term expansion in the construction industry, has influenced designers and developersto choose substitute materialsthat are suitable for the use in constructions. The rising demand for cement, fine aggregate, coarse aggregate, and concrete will be met by partially replacing cement ,fine aggregate ,coarse aggregate, and concrete. The purpose of this experiment is to see if substituting rice husk ash ,quarry dustand recycled aggregate for cement, fine aggregate, and coarse aggregate affects the structural properties of concrete. Theworkability and strengthparameters of concrete will be investigated. The M-20 grade concrete mixes is prepared with six percentages (0, 10, 15, 20, 25, and 30) of rice husk ashh as a partial replacementt for cementt, six percentages of quarry dust as a partial replacement for fine aggregate, and six percentages of recycleddd aggregate as aa partialllreplacementtt for coarseeaggregatee.The Slump test willl be performed on fresh concrete, while the Compressive Strengthh test will be performed on hardenedd concrete moulds after 7, 14, 21, and 28 days in water. As a result, rice husk waste, quarry dust, and demolished concrete can be used in construction in a sustainable manner.
