Evaluation of pre coated recycled concrete aggregate

Application of Double-Coated Recycled Concrete Aggregates ...

It was therefore referred to as a double coating technique (DCT). Mixes made with 0%, 20%, 40%, and 60% of double coated recycled concrete aggregates (DCRCAs) were evaluated through Marshall parameters, indirect tensile strength (ITS), tensile strength ratio (TSR), and indirect tensile stiffness modulus (ITSM) tests.

Concrete recycling - Wikipedia

Concrete recycling is the use of rubble from demolished concrete structures. Recycling is cheaper and more ecological than trucking rubble to a landfill. Crushed rubble can be used for road gravel, revetments, retaining walls, landscaping gravel, or raw material for new concrete.Large pieces can be used as bricks or slabs, or incorporated with new concrete into structures, a material called ...
