To investigate the recovery effect of natural self-healing of freeze-thaw damage of cementitious material-poor hydraulic concrete. we carried out a natural self-healing test for hydraulic concrete damaged by up to 200 rapid freeze-thaw cycles. The self-healing effect of macro-mechanical properties of hydraulic concrete damaged by freeze-thaw cycles was quantitatively characterized by ... https://fitnessgravesyardes.shop/product-category/elevation-assembly/
