Embodiment 1
[0023] First, the cement and 70% fine aggregate (fine sand) which account for 13.75% of the total mass of the mortar are taken into the drying room through the conveyor belt for rapid drying and standby; the dried cement and fine aggregate are transported to the conical disperser Disperse and pre-mix for 20 minutes; then add 0.16% admixture, 2.7% polymer rubber powder, 5.0% silicon powder of ultrafine wear-resistant composite micropowder, 2.5% expansion agent and 2.5% vitrified micropowder in sequence. The beads are dispersed for the second time; at the same time, slowly add steel-plastic fibers accounting for 0.10% of the total mass of the mortar at the first inlet on the top. After adding the steel-plastic fibers, continue to disperse for 15 minutes. After vacuuming, plastic seal and store. During construction, you only need to open the vacuum package, add an appropriate amount of water according to the proportion to reconcile, stir, let it stand for 15 minutes, and then stir...
Embodiment 2
[0025] First, the cement and 74% fine aggregate (fine sand) which account for 13.75% of the total mass of the mortar are taken into the drying room through the conveyor belt for rapid drying and standby; the dried cement and fine aggregate are transported to the conical disperser Disperse and pre-mix for 20 minutes; then add 0.10% admixture, 1.3% polymer rubber powder, 2.5% silicon powder of ultrafine wear-resistant composite micropowder, 1.25% expansion agent and 1.25% vitrified micropowder in sequence. The beads are dispersed for the second time; at the same time, slowly add steel-plastic fibers accounting for 0.08% of the total mass of the mortar at the first inlet on the top. After adding the steel-plastic fibers, continue to disperse for 15 minutes. After vacuuming, plastic seal and store. During construction, you only need to open the vacuum package, add an appropriate amount of water according to the proportion to reconcile, stir, let it stand for 15 minutes, and then st...
Embodiment 3
[0027] Firstly, take 13.75% cement and 73% fine aggregate (fine sand) of the total mass of the mortar and enter the drying room through the conveyor belt for rapid drying and standby; transport the dried cement and fine aggregate to the conical disperser Disperse and pre-mix for 20 minutes; then add 0.15% admixture, 2% polymer rubber powder, 3.5% silicon powder of ultrafine wear-resistant composite micropowder, 2.1% expansion agent and 2% vitrified micropowder in sequence. The beads are dispersed for the second time; at the same time, slowly add steel-plastic fibers accounting for 0.09% of the total mass of the mortar at the first inlet on the top. After adding the steel-plastic fibers, continue to disperse for 15 minutes. After vacuuming, plastic seal and store. During construction, you only need to open the vacuum package, add an appropriate amount of water according to the proportion to reconcile, stir, let it stand for 15 minutes, and then stir for 2 minutes before it can b...
