To investigate the behaviour of recycled aggregate concrete (RAC) under combined compression and shear stresses. 75 hollow cylinder specimens prepared with various replacement ratios of recycled coarse aggregate (RCA) were tested with a self-designed loading device. The results showed that the failure pattern was similar for RAC with different replacement ratios of RCA. The ultimate s... https://poolsproductscanadas.shop/product-category/pentair-challenger-parts/
