Abstract:In order to explore the relationship between damping performance, compressive strength and splitting strength of brick-rich recycled concrete and sanding ratio, 6 groups of regenerated concrete beams, compressive strength and splitting specimens with different mix ratios of 25%~50% were designed by selecting the whole regenerated coarse aggregate rich in brick particles and taking the sand rate as the research parameter. The effects of sand ratio on the damping performance, compression resistance and splitting strength of brick-rich recycled concrete beams were studied by experiments. The results show that with the increase of sand rate, the compressive strength and splitting strength of brick-rich recycled concrete decrease, while the damping ratio increases first and then decreases slightly with the increase of sand ratio.
