Strength and stiffness of compacted crushed concrete

Dec 01 2013The strength and stiffness of CCA with a maximum particle size D max =37 5 mm obtained from a typical concrete crushing plant are noticeably lower than CCA sieved to D max =19 mm compacted using the same energy However when compacted to the same dry density the original CCA exhibits the strength and stiffness higher than the sieved CCA
