Embodiment 1
[0028] A sand-based water-permeable dry-mixed mixture, including the following raw materials by weight: 300 parts of P.O42.5 cement, 60 parts of S95 grade slag powder, 18 parts of SR type ecological permeable concrete enhancer, particle size 2.5-5mm 1648 parts of aggregate, 0.62 parts of polycarboxylic acid water-reducing agent powder, 0.38 parts of hydroxypropyl methyl cellulose ether, and 0.38 parts of regulator.
[0029] All the above-mentioned raw materials are dried and kept dry after cooling. The above-mentioned raw materials are mixed according to the formula amount to prepare a sand-based permeable dry-mixed mixture, which is sealed and stored.
[0030] When in use, water is added to the sand-based permeable dry-mixed mixture to prepare a sand-based permeable mixture. In this embodiment, the weight of water added is 5.4% of the weight of the dry-mixed mixture.
Embodiment 2
[0032] A sand-based water-permeable dry-mixing material, including the following raw materials by weight: 360 parts of P.O42.5 cement, 30 parts of S95 grade slag powder, 25 parts of SR type ecological permeable concrete enhancer, particle size 1.25-2.5 mm aggregates 1495 parts, polycarboxylic acid water reducing agent powder 0.81 parts, hydroxypropyl methyl cellulose ether 0.41 parts, regulator 0.41 parts, iron oxide green 15 parts.
[0033] All the above-mentioned raw materials are dried and kept dry after cooling. The above-mentioned raw materials are mixed according to the formula amount to prepare a sand-based permeable dry-mixed mixture, which is sealed and stored.
[0034] When in use, water is added to the sand-based permeable dry-mixed mixture to obtain a sand-based permeable mixture. In this embodiment, the weight of the added water is 5.6% of the weight of the dry-mixed mixture.
Embodiment 3
[0036] A sand-based water-permeable dry-mixed mixture, including the following raw materials by weight: 320 parts of P.O42.5 cement, 40 parts of S95 grade slag powder, 23 parts of SR type ecological permeable concrete enhancer, particle size 0.63-1.25 mm aggregate 1483 parts, polycarboxylic acid water reducer powder 0.77 parts, hydroxypropyl methyl cellulose ether 0.38 parts, regulator 0.38 parts.
[0037] All the above-mentioned raw materials are dried and kept dry after cooling. The above-mentioned raw materials are mixed according to the formula amount to prepare a sand-based permeable dry-mixed mixture, which is sealed and stored.
[0038] When in use, water is added to the sand-based permeable dry-mixed mixture to obtain a sand-based permeable mixture. In this embodiment, the weight of water added is 6.0% of the weight of the dry-mixed mixture.
