Abstract: At present, ready-to-use concrete is rampant adopted in building construction, but it is often excess supply and the rest is sometimes discarded in any place which could directly reduce the soil fertility and damage the balance of the ecosystem. Thus, recycle concrete waste is a solution to overcome the problem. However, the utilization of waste as recycled aggregate needs to be studied more deeply, by conducting experimental testing and analysis of the characteristics possessed. The methods and procedures for the implementation of recycled aggregate testing are carried out with reference to ASTM standards. In this study, the concrete base material which is coarse aggregate in the form of split is replaced with light concrete debris waste (LPBR) with composition (50% LPBR and 50% Split) and the average compressive strength is measured. The composite samples are tested on 28th day, the concrete compressive strength and modulus of elasticity results indicated 17.740 MPa and 20024.43 MPa respectively.
