- Abstract
Demolition of structure produces waste of clay bricks, which is usually disposal in landfills. Using the recycled waste made from crushed fired clay brick in concrete producing is a possible alternative and leads to a cleaner environment. This research describes experimental tests to evaluate using crushed fired clay brick waste as partial replacement of coarse aggregate in concrete mix. The compressive strength and the slump of concrete containing crushed clay brick aggregates partially replacing normal aggregates has been compared against concrete with normal gravel aggregates. Sixteen compressive tests on 150 mm cubes at 7 days and 210 days ages of concrete have been conducted. Coarse aggregates have been partially replaced by crushed clay brick at 25 percent of the weight. The amount of normal Portland cement (Type 1), water, and fine aggregate has not been changed. The results show that the compressive strength of concrete made with 25% clay brick aggregates has not shown a significant reduction in the compressive strength. Recycling crushed clay brick aggregates in concrete production can be a promising practice, which could reduce the cost and give better environmental aspects.
