Abstract

Utilization of recycled concrete aggregates as an alternative material for natural aggregates in concrete have been of greater importance due to its disposal problems followed by the problem on scarcity in construction materials namely aggregates. This paper presents a study on the mechanical properties of concrete manufactured with recycled aggregates collected from a 10 year old demolished building at the institute. Recycled aggregates were immersed in water for 24 h before its utilization in concrete to achieve surface saturated dry density. A total of 8 batches of Recycled Aggregate Concrete and 2 batches of Normal Aggregate Concrete under different replacement levels of 0%, 10%, 20%, 30% and 40% and at two w/c ratios of 0.45 and 0.5 were manufactured. Various parametric tests such as compressive strength, split tensile strength, flexural strength and elastic modulus were performed to study its mechanical properties at the age of 7 days and 28 days. Results indicate that the mechanical properties of RAC was greatly influenced by the w/c ratio as the pre-saturation of recycled aggregates for 24 h prior to manufacturing yielded better strength even at 0.45w/c ratio and at 30% replacement.
