Abstract
The invention discloses a kind of concrete antifreeze additives, are made of following substance：Polyacrylamide, polyvinyl alcohol, dimethyl carbonate, furazolidone, neopelex, glycerine, natural gum, cornstarch, copper sulphate, calcium sulfate.Antifreeze additive of the present invention can effectively promote the freezing tolerance of concrete, it can be used under subzero 15 DEG C or so of weather condition, hence it is evident that improve the durability of concrete, its 100 freezing-thawing strength damages is made to lead no more than 3%, 90 days shrinkage ratios are no more than 97%, great popularizing value.
Description
Technical field
The invention belongs to concrete working process technical fields, and in particular to a kind of concrete antifreeze additive.
Background technology
Concreting in cold-weather, since concrete temperature and outside air temperature have difference, in concrete and ambient temperature
Between can generate heat exchange, when environment temperature is very low, this heat exchange will soon reduce the temperature of concrete, to newly mixing
For concrete, the speed that temperature reduces determines the size of hydration temperature, and temperature reduction is faster, and the growth of concrete strength is cured
Slowly, after concrete is premature endures cold, intensity would not increase again, still also just higher in the free moisture of inside concrete, knot
Body after the reason of frost-heave force after jelly is just bigger, and concrete is easy for damaging, and concrete strength reduces mainly water freezes
Product increase, frost heave stress just generate crack therewith increasing, and concrete structure is destroyed, in the first few of concreting
At the time of hour is dangerous maximum, the durability of concrete may damage concrete structure by first and second Frozen-thawed cycled, and
The excellent concrete antifreezer of performance can make concrete delay the process of freezing, and extend critical intensity, generate certain freeze proof energy
Power.The problems such as existing common most concrete antifreezers are single there is ingredient, and antifreeze additive effect is bad.
Invention content
The purpose of the present invention is being directed to the problem of existing, a kind of concrete antifreeze additive is provided.
The present invention is achieved by the following technical solutions：

Preferably, it is made of the substance of following parts by weight：
4 parts of polyacrylamides, 2 parts of polyvinyl alcohol, 0.5 part of dimethyl carbonate, 0.2 part of furazolidone, 2.5 parts of detergent alkylate sulphurs
Sour sodium, 5 parts of glycerine, 1.5 parts of natural gum, 2 parts of cornstarch, 0.03 part of copper sulphate, 0.04 part of calcium sulfate.
Further, the average molecular weight of the polyvinyl alcohol is 100000 ~ 130000.
Further, the natural gum is any one of peach gum, japanese plum resin.
The present invention has the following advantages compared with prior art：
The present invention carried out the component of antifreeze additive special adjustment collocation, and polyacrylamide, polyvinyl alcohol are added with
Effect reduces freezing point, has refined the granularity of ice crystal, has reduced destruction of the ice crystal for concrete, dimethyl carbonate, the furan of addition
Oxazolone of muttering contains a large amount of reactive functional, enhances the bond strength between each ingredient such as concrete, natural gum, the jade of addition
Rice starch ingredient is conducive to be promoted the quantity of concrete inner sealing pore, further improves its antifreeze properties.In each ingredient
Under collective effect, antifreeze additive of the present invention can effectively promote the freezing tolerance of concrete, can be at subzero 15 DEG C or so
It is used under weather condition, hence it is evident that improve the durability of concrete, its 100 freezing-thawing strength damages is made to lead no more than 3%, 90 day
Shrinkage ratio is not more than 97%, great popularizing value.
