Experimental study on reuse of recycled concrete ...

2017-9-7  For the lateral load-bearing capacity of BM columns, the ratios of test data to calculation values are 1.72–1.77 and 1.38–1.43 for the BM30 and BM50 columns, respectively. It shows that the lateral load-bearing capacity of recycled concrete filled thin-wall steel tubular columns from the calculation tends to be relatively conservative.

Estimating the resilient modulus of crushed recycled ...

Abstract Since the determination of resilient modulus (Mr) from the repeated load triaxial test is rather complicated, due to the expensive procedure and time-consuming nature, attempts have been made to estimate it using other properties, such as the unconfined compressive strength and California bearing capacity based on empirical models. However, because of the dynamic nature of the Mr, it ...
