Abstract
The invention discloses antifreeze concrete and a preparation method thereof. The antifreeze concrete is prepared by mixing the following raw materials in parts by weight: 20-25 parts of cement, 20-45 parts of coal ash, 10-20 parts of water, 10-20 parts of river sands, 1-2 parts of polymer fibers, 4-6 parts of industrial aluminum sulfate and 15-20 parts of an antifreezing agent. A lithium base is introduced in the antifreezing agent, so that alkali-aggregate reaction can be effectively inhibited; the antifreeze concrete is simple in production process, low in cost, good in antifreezing effect and beneficial to industrial 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 has caused very large impact to concrete stirring, how just can prevent that concrete from freezing at low temperatures is the relatively problem of headache of engineering staff always.
Nitrate, the nitrite of adopting prevent that as antifreeze component concrete from freezing more on the market now, and still, this method makes the concrete alkalinity suddenly increase, and even occurs that the accumulation of salt in the surface soil is present, has 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 ℃, 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 part proportioning of described polyvinyl alcohol fiber and described polypropylene fibre is 7:3.
Preferably, described industrial aluminum sulphate adopts 6 parts.
Preferably, described frostproofer is mixed and is formed by lithium acetate and sodium acetate.
Preferably, in described lithium acetate and described sodium acetate, the mol ratio of lithium and sodium is 0.3-0.5.
A kind of preparation method of frost-resistant concrete, comprise 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): take the polyvinyl alcohol fiber of 7 parts and the polypropylene fibre of 3 parts and mix rear the stirring 40 minutes, make polymer fiber;
Step (3): the polymer fiber that adds 2 parts of steps (2) to make in the mixture made in step (1), stir 1 hour;
Step (4): will after the proportioning mixing and stirring that be 0.3-0.5 by the mol ratio of lithium and sodium in lithium acetate and described sodium acetate, make frostproofer;
Step (5): by the frostproofer made in step (4), be added in the middle gained mixture of step (3), then stir 2-3 hour, can use.
The invention has the beneficial effects as follows: the present invention has introduced the lithium base in frostproofer, can effectively suppress alkali-aggregate reaction, and production process of the present invention is simple, and cost is low, and good freezing protection effect, more is conducive to suitability for industrialized production.
