Embodiment 1

[0037] see Figure 1-6 As shown, a kind of impermeable and frost-resistant concrete is characterized in that: it is composed of the following raw materials in parts by weight: 820 parts of machine-made sand, 950 parts of gravel, 7 parts of water reducing agent, 115 parts of water, 50 parts of air-entraining agent, antifreeze 50 parts of agent; wherein, the air-entraining agent is the mixture of saponin and dodecyl dimethylamine oxide, and the weight ratio of saponin and dodecyl dimethylamine oxide is 100:2; antifreeze The agent is a mixture of sodium nitrite and urea, and the weight ratio of sodium nitrite and urea is 8:8;

[0038] The preparation method of the anti-seepage and frost-resistant concrete comprises the following steps:

[0039] Step 1: Cut saponins into granules, add them into the cleaning frame, and then control the rotating motor to work through the transfer device 3 on the bracket 1, and drive the rotating shaft 9 to rotate, so that the rotating plate 10 driv...

Embodiment 2

[0049] Compared with Example 1, the difference lies in: an impermeable and frost-resistant concrete, characterized in that it is composed of the following raw materials in parts by weight: 840 parts of machine-made sand, 980 parts of gravel, 9 parts of water reducing agent, and 120 parts of water , 55 parts of air-entraining agent, 55 parts of antifreeze; Wherein, the air-entraining agent is the mixture of saponin and dodecyldimethylamine oxide, the mixture of saponin and dodecyldimethylamine oxide The weight ratio is 105:3; the antifreeze is a mixture of sodium nitrite and urea, and the weight ratio of sodium nitrite and urea is 9:9;

Embodiment 3

[0051] Compared with Example 1, the difference is: an impermeable and frost-resistant concrete, characterized in that it is composed of the following raw materials in parts by weight: 860 parts of machine-made sand, 1000 parts of gravel, 11 parts of water reducing agent, and 125 parts of water , 60 parts of air-entraining agent, 60 parts of antifreeze; Wherein, the air-entraining agent is the mixture of saponin and dodecyldimethylamine oxide, the mixture of saponin and dodecyldimethylamine oxide The weight ratio is 110:4; the antifreeze is a mixture of sodium nitrite and urea, and the weight ratio of sodium nitrite and urea is 10:10;

[0052] Working principle of the present invention: an anti-seepage and frost-resistant concrete, characterized in that it is composed of the following raw materials in parts by weight: 820-860 parts of machine-made sand, 950-1000 parts of crushed stone, 7-11 parts of water reducing agent, and 115 parts of water -125 parts, 50-60 parts of air-ent...

Abstract

The invention discloses an impermeable frost-resistant concrete. The concrete is characterized by being prepared from the following raw materials in parts by weight: 820-860 parts of machine-made sand, 950-1000 parts of gravels, 7-11 parts of a water reducing agent, 115-125 parts of water, 50-60 parts of an air entraining agent and 50-60 parts of an anti-freezing agent. The air entraining agent isa mixture of saponin and dodecyl dimethyl amine oxide, and the weight ratio of saponin to dodecyl dimethyl amine oxide is 100-110: 2-4; the anti-freezing agent is a mixture of sodium nitrite and urea, and the weight ratio of sodium nitrite to urea is 8-10: 8-10; after the concrete provided by the invention is hardened, tiny bubbles are still reserved to improve the impermeability and the frost resistance and durability of the concrete; and the concrete also has the advantage of good anti-freezing and coagulation-promoting effects.

Description

technical field [0001] The invention belongs to the technical field of concrete, in particular to an anti-seepage and frost-resistant concrete and a preparation method thereof. Background technique [0002] Concrete is the most used building material today, and high-performance concrete represents the development direction of concrete technology. [0003] Reference document CN106380140A is an impermeable and frost-resistant concrete. The raw materials of the concrete include the following components: Portland cement, coarse sand, medium coarse sand, crushed stone, water, silica fume, alum stone, slaked lime, and magnesium oxide powder , Coal ash powder, AEA high-strength clinker, gypsum, water reducing agent, air-entraining agent, polyvinyl alcohol fiber, glass fiber, carbon fiber, siloxane, paraffin, nitrite, sodium benzoate. [0004] In the prior art, the performance of concrete in terms of frost resistance and impermeability is not good, and the traditional concrete mixi...
