The development of compressive strength of recycled aggregate concrete at the age of 1,3,7,14,28, 56, and 90 days; the development of tensile flexural strength at the age of 1,3,7,14 and static modulus of elasticity at the age of 28 days are investigated.
CONCRETE CONTAINING RECYCLED CONCRETE .
A research by Smith et all (2009) on concrete containing 0%, 15%, 30%, and 50% of coarse RCA showed that as the coarse RCA content increased the CTE decreased. Hansen (1986) found that creep for concrete manufactured from recycled aggregates to be 30% to 60% greater than concrete manufactured from materials.
