Review on Recycled Concrete Aggregates
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2014, Vol 2, Issue 9
Abstract
This review paper focuses on the mechanical and durability properties of concrete made with recycled concrete aggregates (RCA). Various techniques used by researchers: 1) replacing the proportion of normal aggregates by various recycled aggregate ie. RCA clay bricks, recycled marble, recycled granite and 2) replacing the ordinary Portland cement by flyash, baggese ash. The results observed showed 1) 25- 30% replacement with RCA showed minimal deteriorating effect and 2) whereas in case of recycled marble and granite in the form of recycled coarse aggregates performed well in the crushing test and displayed superior nature compared to natural aggregates. Tensile strength, flexural strength and resistance against sulphate attack; concrete made with RCA was inferior to control concrete whereas marble and granite in form of coarse aggregates was superior to control concrete.
