But, the impact and crushing value of RCA are comparatively less than NA. The results of compressive strength shows that, the use of RCA up to 40% affect the functional requirements of concrete structure. Also the result of slump test shows there is continuous decrease in workability of concrete mix, as the cement mortar paste is attached to RCA.
