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 cement blocks. The result showed that an increase in percentage of RCA decreases the workability and compressive strength. The 25% replacement of RCA in proportion of 1:6.66:10, concrete block shows maximum strength and recommended for field applications.
