Embodiment 1

[0015] Embodiment 1, the raw material ratio of the high-strength permeable concrete admixture of the present invention is: 50 kg of water reducer, 100 kg of rubber powder, 180 kg of pigment, 80 kg of asbestos, 150 kg of raw gypsum powder, and 100 kg of heavy calcium powder.

[0016] The water reducer is preferably a naphthalene-based high-efficiency water reducer. The rubber powder is preferably redispersible latex powder, more preferably Wacker rubber powder suitable for bonding. The pigment is iron oxide red or iron yellow, more preferably iron red. The preparation method is that the raw materials in the weight ratio are uniformly prepared through mechanical mixing.

Embodiment 2

[0017] Embodiment 2, the raw material ratio of the high-strength permeable concrete admixture of the present invention is: 100 kg of water reducer, 120 kg of rubber powder, 300 kg of pigment, 100 kg of asbestos, 200 kg of raw gypsum powder, and 100 kg of heavy calcium powder.

[0018] The water reducer is preferably a naphthalene-based high-efficiency water reducer. The rubber powder is preferably redispersible latex powder, more preferably Wacker rubber powder suitable for bonding. The pigment is iron oxide red or iron yellow, more preferably iron red. The preparation method is that the raw materials in the weight ratio are uniformly prepared through mechanical mixing.

Embodiment 3

[0019] Embodiment 3, the raw material ratio of the high-strength permeable concrete admixture of the present invention is: 50 kg of water reducing agent, 120 kg of rubber powder, 180 kg of pigment, 100 kg of asbestos, 150 kg of raw gypsum powder, and 100 kg of heavy calcium powder.

[0020] The water reducer is preferably a naphthalene-based high-efficiency water reducer. The rubber powder is preferably redispersible latex powder, more preferably Wacker rubber powder suitable for bonding. The pigment is iron oxide red or iron yellow, more preferably iron red. The preparation method is that the raw materials in the weight ratio are uniformly prepared through mechanical mixing.

Abstract

The invention relates to a high strength permeable concrete additive and permeable concrete. The invention aims to overcome the problem of low strength of permeable concrete. The high strength permeable concrete additive comprises the following raw materials by weight: 50 to 100 of a water reducer, 100 to 120 of rubber powder, 180 to 300 of pigments, 80 to 100 of asbestos wool, 150 to 200 of gypsum powder and 100 of heavy calcium powder. The prepared permeable concrete is characterized in that: the weight ratio of the additive to cement in the concrete is 30 to 35%, and there is 15 to 18 wt %of iron ore slag in the concrete. The balance in the concrete is gravel and water. The prepared concrete has the following advantages: good water penetration and good permeability are obtained; when it is raining, no water is accumulated on the concrete, splashing of rainwater is mitigated, and occurrence of the phenomenon that shoes, wheelchairs and the like are wetted is reduced; high load-bearing capability and superior environment-friendliness are achieved; good security and a beautiful visual effect are realized, and car accidents caused by reflection of headlights at night in a rainy day are reduced; when the concrete is used for an antiskid track, occurrence of the phenomenon of water mist is reduced, and traffic accidents are prevented; the advantage of reutilization of waste resources is achieved.

Description

technical field [0001] The invention relates to a concrete additive, in particular to a high-strength permeable concrete admixture and permeable concrete. Background technique [0002] The existing permeable concrete can meet the requirement of water permeation effect, but the strength is often not up to the requirement, let alone be made into a permeable concrete pavement for vehicles to run on. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned defects of the prior art, and to provide a high-strength permeable concrete admixture with good water permeability and strength. The purpose of the present invention is also to provide a high-strength permeable concrete made with the admixture . [0004] In order to achieve the above object, the high-strength permeable concrete admixture of the present invention is special in that the weight ratio of raw materials is: water reducer 50-100, rubber powder 100-120, pigment 180-...
