Abstract |
|
The use of construction waste as a source of aggregate for the production of new concrete has become more common in recent decade. RCA are the crushed concrete materials obtained from demolition of concrete structures. This paper aims to evaluate the physical properties of concrete using RCA with 0%, 25%, 50%, 75% and 100% by weight of NCA in M30 and M40 concrete. The result showed that an increase in percentage of RCA decreases the workability, compressive, flexural and split tensile strength and Modulus of elasticity. The 25% and 50% replacement of RCA in M30 and M40 grade concrete respectively shows maximum strength and recommended for field applications. |
