Abstract:

In this present work the study on replacement of coarse aggregate by demolished brick aggregate. Coarse aggregate can be defined as inert granular materials such as gravel, crushed stone and sand. Coarse aggregate is one of the essential ingredients apart of water and cement in concrete production. The only variable considered in this study was the volumetric replacement (0%, 25%, 50%, 75%, and 100%) of stone aggregate by brick aggregate. The use of brick aggregate as a replacement of stone aggregate resulted reductions in unit weight, compressive strength of concrete. Different relations for determination of compressive strength, splitting tensile strength of mix-aggregate concrete have been tentatively proposed. The 25% replacement of RCBA is considered as the best in view of strength and economy, hence we use it in moderately loaded structures. 50% replacement of RCBA can be used wherever load coming chances are less. Can be rectified, but few of them can be overcome by improving management responsibilities.
