Due to urbanisation and rapid development in Malaysia, the waste generated from the construction has increased tremendously. Such waste accumulation has been a major issue not only in Malaysia but also worldwide. In line with this, recycling construction as coarse aggregate can be introduced to solve two environmental aspects namely waste disposal crisis while protecting from depleted natural resources. In this study, three types of construction waste namely floor tiles, clay bricks and crushed concrete aggregate were used to replace coarse aggregate in concrete production. The effect of coarse aggregate replacement on the workability, compressive strength, and flexural strength Grade 30 concrete were investigated and discussed. The concrete specimens that made of crushed floor tiles, crushed bricks, and crushed concrete aggregate were termed as tile concrete (TC), brick concrete (BC) and crushed aggregate concrete (CAC). The result for all specimens has shown good workability with slump ranging from 51-85 mm. BC showed optimum brick replacement of 17% with the 28-day compressive strength of 36 N/mm2. TC and CAC on the other hand showed optimum result at 20% and 16% replacement with 28-day compressive strength of 31.43 N/mm2 and 31.25 N/mm2 respectively. It can be concluded that optimum result for BC, TC and CAC have achieve concrete G30. The flexural strength of BC, TC and CAC ranges from 3.03-4.49 N/mm2, 3.62-4.60 N/mm2, and 4.05-5.43 N/mm2.
