stone aggregate. When removed from the mold, wet cast units exhibit a surface film of cement paste, which must be removed to expose the aggregate. Partially cured units could be sprayed with water, rubbed with natural bristle brushes, etched with acid, or sandblasted to remove the cement layer. The surface of dry tamp products required less finish­

In this experimental study, different mixes are casted, waste crushed tiles are used to partially replace the coarse aggregate by 10% and 20% and tiles powder is used to partially replace the fine aggregate by 10% and 20%. Both coarse and fine aggregates also partially replaced by these waste materials at different percentages.
