Abstract
The invention discloses a kind of anti-freezing agent for concretes, including each component by weight as follows：18 ~ 34 parts of 35 ~ 45 parts of calcium chloride, 32 ~ 43 parts of urea, 27 ~ 41 parts of citric acid, 25 ~ 36 parts of polyvinyl alcohol, 23 ~ 29 parts of sodium sulfite, 17 ~ 25 parts of methanol, 15 ~ 21 parts of potassium chloride, 13 ~ 19 parts of methyl α-naphthyl acetate, 10 ~ 14 parts of neopelex, 9 ~ 12 parts of polyethylene and water.The resistance to frost and durability of concrete can be improved in the present invention.
Description
Technical field
The invention belongs to technical field of buildings, and in particular to a kind of anti-freezing agent for concretes.
Background technology
Early strength antifreezing agent can effectively be reduced the freezing point of concrete, mortar, be greatly improved coagulation using extraordinary frost-resistant material
Soil, anti-freezing property of the mortar under subzero temperature, and the early strength of concrete, mortar can be made to improve 80% or more, later strength does not drop
It is low, to ensure that intensity is equally developed under the conditions of positive and negative mild subzero temperature.
Invention content
To solve the deficiencies in the prior art, the purpose of the present invention is to provide a kind of resistance to frost that concrete can be improved and
The anti-freezing agent for concretes of durability.
In order to realize that above-mentioned target, the present invention adopt the following technical scheme that：
A kind of anti-freezing agent for concretes, including each component by weight as follows：35 ~ 45 parts of calcium chloride, 32 ~ 43 parts of urea,
27 ~ 41 parts of citric acid, 25 ~ 36 parts of polyvinyl alcohol, 23 ~ 29 parts of sodium sulfite, 17 ~ 25 parts of methanol, 15 ~ 21 parts of potassium chloride, naphthalene second
18 ~ 34 parts of 13 ~ 19 parts of acid, 10 ~ 14 parts of neopelex, 9 ~ 12 parts of polyethylene and water.
Preferably, aforementioned anti-freezing agent for concretes includes following each component by weight：35 parts of calcium chloride, urea 32
Part, 27 parts of citric acid, 25 parts of polyvinyl alcohol, 23 parts of sodium sulfite, 17 parts of methanol, 15 parts of potassium chloride, 13 parts of methyl α-naphthyl acetate, dodecane
18 parts of 10 parts of base benzene sulfonic acid sodium salt, 9 parts of polyethylene and water.
The invention has the beneficial effects that：The resistance to frost of concrete and resistance to can be improved in the anti-freezing agent for concretes of the present invention
Long property, the concrete construction process being effectively improved under low-temperature condition.
Specific implementation mode
Specific introduce is made to the present invention below in conjunction with specific embodiment.
Embodiment 1
Anti-freezing agent for concretes includes following each component by weight：35 parts of calcium chloride, 32 parts of urea, 27 parts of citric acid,
