EFFECT OF BRICK DUST ON SOME PROPERTIES OF CONCRETE

Abstract

In today's world, concrete is the most durable and widely utilized construction material. Efforts have been made to boost some unique features of concrete by adding pozzolanic elements to improve its strength characteristics and other properties for different uses. Some of the materials have been effectively used to improve concrete's fresh properties, such as consistency, workability, bleeding and settlement, plastic shrinkage, and so on, as well as its hardened properties, such as durability, strength, density, porosity, thermal and acoustic insulation, impact resistance, and so on. As a result of increased demand, natural assets have become exceedingly expensive as building materials, raising the project's overall cost. Efforts are being made to incorporate waste components into concrete, which are environmentally detrimental, readily available, and reduce the project's overall cost. The use of these waste elements in concrete reduces waste in the environment while also lowering the overall cost of structures without compromising concrete quality.Brick dust can be replaced with cement up to a certain proportion without compromising the concrete's qualities. The goal of this research is to see if brick dust may be used as a cement substitute in concrete production. In varying quantities, brick dust was used in place of cement in concrete. The performance of concrete containing brick dust was compared to the control samples developed for this investigation. In all concrete samples, the water-cement ratio was standardized at 0.65.To fulfill the study's goal, brick dust was crushed and added to the concrete mixture to substitute cement in varying proportions of 0%, 5%, 10%, and 15%. Workability and compressive strength testing were carried out in the laboratory for 7, 14, and 28 days. The results show that a 10% replacement proportion of brick dust in concrete over 28 days of curing enhanced the compressive strength of the concrete when compared to control specimens and laboratory testing. The workability of the concrete increases with the addition of brick dust to the mix. As a result, it has been established that substituting brick dust in the concrete production process is suitable.
