Embodiment 1
[0027] Permeable anti-corrosion concrete, prepared from the following raw materials in parts by weight: 1450 parts of coarse aggregate, 30 parts of adhesive, 330 parts of Portland cement, 7 parts of polypropylene fiber, 30 parts of fine aggregate, and 120 parts of water .
[0028] The coarse aggregate is basalt crushed stone.
[0029] The Portland cement is P.O 42.5R Portland cement.
[0030] The adhesive is polyurethane adhesive.
[0031] The processing method of the polyurethane adhesive is as follows: add polyether polyol and diphenylmethane diisocyanate into the reaction kettle under nitrogen at a mass ratio of 1:0.15, at a temperature of 80°C, at a speed of 300r / min stirring reaction for 3h; control the temperature to 80°C, add 0.2% of polyether polyol weight dibutyltin dilaurate at a speed of 300r / min and stir for 30min, then add 0.75% of polyether polyol weight ethylenediamine at a speed of Stir at 300r / min for 6min, finally add 2% by weight of polyether polyol 1,4-...

[0036] Permeable anti-corrosion concrete, prepared from the following raw materials in parts by weight: 1450 parts of coarse aggregate, 30 parts of adhesive, 330 parts of Portland cement, 7 parts of polypropylene fiber, 30 parts of fine aggregate, and 120 parts of water .
[0037] The coarse aggregate is basalt crushed stone.
[0038] The Portland cement is P.O 42.5R Portland cement.
[0039] The adhesive is a modified polyurethane adhesive.
[0040] The processing method of the modified polyurethane adhesive is: polyether polyol, 3-(2,3-epoxypropoxy)propyltrimethoxysilane, 1-butyl-3-methylimidazolium tetrafluoro Add borate acetone solution and diphenylmethane diisocyanate into the reaction kettle under nitrogen gas at a mass ratio of 1:0.05:0.1:0.15, and stir and react at a temperature of 80°C at a speed of 300r / min for 3 hours; Control at 80°C, add 0.2% of polyether polyol weight dibutyltin dilaurate at a speed of 300r / min and stir for 30min, then add 0.75% of polyether p...

[0046] Permeable anti-corrosion concrete, prepared from the following raw materials in parts by weight: 1450 parts of coarse aggregate, 30 parts of adhesive, 330 parts of Portland cement, 7 parts of polypropylene fiber, 30 parts of fine aggregate, and 120 parts of water .
[0047] The coarse aggregate is basalt crushed stone.
[0048] The Portland cement is P.O 42.5R Portland cement.
[0049] The adhesive is a modified polyurethane adhesive.
[0050]The processing method of the modified polyurethane adhesive is: polyether polyol, 3-(2,3-epoxypropoxy)propyltrimethoxysilane, and diphenylmethane diisocyanate are 1 in mass ratio: 0.05:0.15 was added to the reaction kettle under nitrogen, and the temperature was 80°C, and the rotation speed was 300r / min. The rotation speed was 300r / min and stirred for 30min, then ethylenediamine with a rotation speed of 0.75% of the weight of polyether polyol was added and the rotation speed was 300r / min and stirred for 6min, and finally 1,4-but...
