Crushing concrete to bring the aggregates back to be used for concrete structures is a process of creating recycled aggregate (RA). Recycled aggregate concrete (RAC) has become increasingly important in the field of construction. The use of recycled aggregate concrete made from recycled aggregate in civil engineering construction projects such as highways will provide both economic and ...
Prototypes of columns were cast with different percentages of rebars and stirrups and various alkali–silica reactive aggregates. The deformations of concrete were measured along the three directions using surface metal studs and internal vibrating wire gauges.
Guide for Cement Concrete Association of New Zealand (CCANZ) 8 has show that the charges applying 10/ton on land fill dumping often make recycling concrete aggregate (RCA) a preferred option. The use of RCA to conserves natural aggregate the associated environmental cost of exploration transportation waste
aggregates is that they improve the durability of concrete. Concrete aggregates can sometimes contain impurities like clay particles which can have an impact on the concrete properties. The earliest description of surface coatings on coarse aggregates was documented by Goldbeck (1932) for the Highway Research Board.

Polymer concrete was introduced in the late 1950s and became well known in the 1970s for its use in repair, thin overlays and floors, and precast components. Because of its properties like high compressive strength, fast curing, high specific strength, and resistance to chemical attacks polymer concrete has found application in very specialized domains.
