Experimental Investigation of Recycle Concrete Aggregate

2016-9-16  Recycled coarse aggregate can also be widely used as sub base in road project and also for making lean concrete. Research works are in progress to establish it to be fit for structural concrete. Successful use of recycled aggregats in regular concrete works would lead to a considerable reduction in demand of natural aggregates. Recycled aggregate may be considered as a green material to some extent. It is quite well known that the porosity of recycled aggregate concrete is more than conventional natural aggregate concrete. concrete, unless carefully managed and controlled, is likely to have a negative influence on most concrete properties, compressive strength, modulus of elasticity, shrinkage and creep, particularly for higher strength concrete. Also the use of fine recycled aggregate below 2 mm is uncommon in recycled aggregate concrete
