In order to investigate the mechanical properties. damage mode and energy evolution of loess-slag-based cementitious filling materials under different water-cement ratios and curing ages. slump tests and uniaxial compression tests were conducted on loess-slag-based cementitious filling materials under four sets of water-cement ratios and five ages. respectively. https://safeersappliancers.shop/product-category/bertazzoni-p905lmodx-gas-hob/
