Abstract
The invention discloses a kind of frost-resistant concrete and preparation method thereof, formed by weight ratio by following raw material: cement 20-25 part; Flyash 20-45 part; Water 10-20 part; River sand 10-20 part; Polymer fiber 1-2 part; Industrial aluminum sulphate 4-6 part; Frostproofer 15-20 part.The present invention introduces lithium base in frostproofer, effectively can suppress alkali-aggregate reaction, and production process of the present invention is simple, and cost is low, and good freezing protection effect, be more conducive to suitability for industrialized production.
Description
Technical field
The present invention relates to building material field, particularly a kind of frost-resistant concrete and preparation method thereof.
Background technology
In building operation, often can run into various atrocious weather environment, especially in the winter time, long-term low temperature causes very large impact to concrete stirring, and how just can prevent concrete from freezing at low temperatures is the problem that engineering staff compares headache always.
Adopt nitrate, nitrite to freeze to prevent concrete as antifreeze component on the market now, but this method makes concrete alkalinity suddenly increase more, even occur that the accumulation of salt in the surface soil is present, had a strong impact on construction quality.
Summary of the invention
The present invention seeks to: propose a kind of frost-resistant concrete and preparation method thereof, it can resist the low temperature environment of subzero 15 DEG C, and can effectively reduce the phenomenon of the accumulation of salt in the surface soil.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of frost-resistant concrete, is formed by weight ratio by following raw material:
Cement 20-25 part;
Flyash 20-45 part;
Water 10-20 part;
River sand 10-20 part;
Polymer fiber 1-2 part;
Industrial aluminum sulphate 4-6 part;
Frostproofer 15-20 part.
Preferably, described polymer fiber adopts 2 parts.
Preferably, described polymer fiber is mixed by polyvinyl alcohol fiber and polypropylene fibre.
Preferably, the weight of described polyvinyl alcohol fiber and described polypropylene fibre is 7:3.
Preferably, described industrial aluminum sulphate adopts 6 parts.
Preferably, described frostproofer is made up of lithium acetate and sodium acetate mixing.
Preferably, in described lithium acetate and described sodium acetate, the mol ratio of lithium and sodium is 0.3-0.5.
A preparation method for frost-resistant concrete, comprises the steps:
Step (1): take following raw material mix and blend by weight ratio:
Cement 20-25 part;
Flyash 20-45 part;
Water 10-20 part;
River sand 10-20 part;
Industrial aluminum sulphate 4-6 part;
Step (2): stir 40 minutes after taking the polypropylene fibre mixing of the polyvinyl alcohol fiber of 7 parts and 3 parts, obtained polymer fiber;
Step (3): add the polymer fiber that 2 parts of steps (2) are obtained in mixture obtained in step (1), stir 1 hour;
Step (4): be obtained frostproofer after the proportioning mixing and stirring of 0.3-0.5 by the mol ratio by lithium and sodium in lithium acetate and described sodium acetate;
Step (5): by frostproofer obtained in step (4), is added in step (3) in gained mixture, then stirs 2-3 hour, can use.
The invention has the beneficial effects as follows: the present invention introduces lithium base in frostproofer, effectively can suppress alkali-aggregate reaction, production process of the present invention is simple, and cost is low, and good freezing protection effect, be more conducive to suitability for industrialized production.
