Abstract
The invention discloses a concrete anti-freezer. The concrete anti-freezer comprises a filling agent, urea, calcium sulphoaluminate, rosin, nitrite, sodium sulfate and a water reducing agent in a ratio of (50-30):(10-20):(10-15):(10-20):20:(30-50). The concrete anti-freezer has the advantages of high reliability, good early flocculating performance, low freezing temperature, good water resistance and impermeability of a finished concrete product, long service life, simple process and the like, and has a wide market prospect in the field of molds.
Description
Technical field
The present invention relates to concrete additive field, particularly relate to a kind of concrete antifreezer.
Background technology
The lower concrete of newly building of winter temperature is not before reaching certain hardenability, free water in concrete is freezed, and the volume with 9% increases, and produces very high internal stress, make hole in concrete especially pore roll up, cause concrete strength and weather resistance to reduce.Need to add admixture and adjust concrete setting characteristic.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of concrete antifreezer, by using the freezing temperature of the reduction water such as frostproofer; Use water-resisting agent to improve Concrete Anti outlet capacity; Add ultra-fine grain fill concrete finedraw; There is the advantages such as high, the early solidifying property of reliability is good, freezing temperature is low, concrete finished product waterproof, seepage control is good, the life-span is long, and technique is simple, in mould applications, have market outlook widely simultaneously.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of concrete antifreezer is provided, comprise: weighting agent, urea, calcium sulphoaluminate, rosined soap, nitrite, sodium sulfate and water reducer, described component proportions is 50-30:10-20:10-15:10-20:20:30-50.
In a preferred embodiment of the present invention, described weighting agent is superfined flyash.
In a preferred embodiment of the present invention, the average particulate diameter of described flyash is 0.5um.
In a preferred embodiment of the present invention, the adding proportion of described concrete antifreezer is 5%.
The invention has the beneficial effects as follows: concrete antifreezer of the present invention is by being used the freezing temperature of the reduction water such as frostproofer; Use water-resisting agent to improve Concrete Anti outlet capacity; Add ultra-fine grain fill concrete finedraw; There is the advantages such as high, the early solidifying property of reliability is good, freezing temperature is low, concrete finished product waterproof, seepage control is good, the life-span is long, and technique is simple, in mould applications, have market outlook widely simultaneously.
Embodiment
Below the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only a part of embodiment of the present invention, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making all other embodiment that obtain under creative work prerequisite, belong to the scope of protection of the invention.
The embodiment of the present invention comprises:
A concrete antifreezer, comprising: weighting agent, urea, calcium sulphoaluminate, rosined soap, nitrite, sodium sulfate and water reducer, described component proportions is 50-30:10-20:10-15:10-20:20:30-50.
Described weighting agent is superfined flyash, effectively fill concrete gap.
The average particulate diameter of described flyash is 0.5um, has good filling effect.
The adding proportion of described concrete antifreezer is 5%, reduces concrete water freezing temperature, improves early solidifying ability and improves agent on crack resistance of concrete outlet capacity.
The beneficial effect of concrete antifreezer of the present invention is:
One, by using the freezing temperature of the reduction water such as frostproofer;
Two, use water-resisting agent to improve Concrete Anti outlet capacity;
Three, add ultra-fine grain fill concrete finedraw;
Four, there is the advantages such as high, the early solidifying property of reliability is good, freezing temperature is low, concrete finished product waterproof, seepage control is good, the life-span is long, and technique is simple, in mould applications, have market outlook widely simultaneously.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes description of the present invention to do; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
