WhatsApp
— The crushed stone aggregate used in the study was obtained from a recycling plant which was established and directed towards reducing waste produced from the construction industry to provide an efficient alternative for the reuse of recycled aggregate Evaluation of the aggregate physical and mechanical properties showed an
WhatsApp
— Fine aggregate one of the primary constituents of concrete along with cement water and coarse aggregates is a term used to describe small inert materials whether granular or crushed stone These fine aggregates are essential components in concrete mixtures and play a crucial role in determining the properties of the resulting
— Debieb and Kenai [] have stated that crushed bricks as fine and coarse aggregates are becoming a serious interest to civil engineers as their use significantly decreases the issue of waste storage and protects natural aggregate it is clear that using recycled construction materials as replacement material in concrete
