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://www.roneverhart.com/HP-Pavilion-15-eg1053cl-15-6-FHD-Touch-Intel-Core-i5-1235U-3-30-GHz-Intel-Iris-Xe-Graphics-12-GB-DDR4-RAM-512-GB-SSD-/
