Abstract In Mauritius, about 1-4% of the total volume of concrete produced in a batching plant turns out to waste. Landfills are becoming scarce and transportation of the waste to landfills is costly. In this paper, the possible use of Fresh Concrete Waste (FCW) is being highlighted to decrease its possible impacts on the environment and as solid waste management strategy. 10%, 15%, 20% and 30% of the total aggregate content of respective concrete mixes were substituted with FCW. The compressive strength, modulus of elasticity and flexural strength of the modified concrete mixes decreased with the increasing FCW content. It was noted however that with 10% replacement of the FCW, a compressive strength of 22 N/mm2 was recorded at 28 days. For same replacement, slight decreases were observed for the plastic density, modulus of elasticity and flexural strength respectively. Thus 10% FCW replacement can be used for blinding layer concrete, kerbs and footpaths, where concrete of compressive strength of 20 N/mm2 is normally used.
