Using RCA in concrete preserves the environment by reducing the need for opening new aggregate quarries and decreases the amount of construction waste that goes into landfill. TheRecycled Concrete Aggregates: Its Properties & Uses,27/06/2019· Properties of Recycled Concrete Aggregates Density: Recycled concrete as aggregate contains residual adhered mortar on the particle of aggregate. Due to which the density of RCA is normally lower than the density of natural aggregate.Use Of Recycled Aggregate In Concrete - ijert.org,the recycled aggregate. The use of recycled aggregate generally increases the drying shrinkage creep & porosity to water & decreases the compression strength of concrete compared to that of natural aggregate concrete. It is nearly 10-30% as per replacement of aggregate. Recycling reduces the cost (LCC) by about 34-41% & CO 2 emission (LCCO 2Mechanical Properties Of Recycled Aggregates Concrete,,Recycled concrete has been primarily used as a unbound material in embankments, bases, and sub-bases. Engineers have also used recycled concrete as an aggregate in the construction of new structures such as concrete pavements but with limited frequency. The use of recycled concrete in load bearing structures has not gained wide acceptance probably because of theA STUDY ON RECYCLED CONCRETE AGGREGATES,The recycled aggregate concrete is made by mixing 60% of recycled aggregates with 40% of crushed stone chips. The aggregates used for concrete batching are maintained at saturated surface dry condition . The workability of the recycled aggregate concrete is slightly lower than that of the conventional concrete.
