The maximum size of coarse aggregate was 10 mm. Stirrups of mild steel of ... chamber under a cycled temperature change. During the test,
the bond failure between recycled coarse aggregate and cement. (2) The recycled concrete compressive strength, tensile strength, and elastic modulus are less than ordinary concrete, but its flexural strength is higher than that of ordinary concrete.
Compressive stressstrain tests performed on drilled cores revealed that the fracture process of cylinders with recycled aggregate mixes is very stable and gradual, unlike the unstable and rapid crack propagation in cylinders with aggregates.

Farny and Kosmatka (1997) recommend that the reactive aggregate should be limited to 20 percent by volume if either the coarse aggregate or the fine aggregate is reactive. If both the coarse and the fine aggregate are reactive, then only 15 percent by volume of the aggregate used should be reactive.
