The invention has the beneficial effects as follows: the preparation method of cold-resistant concrete brick of the present invention, simple to operate, construct in arctic weather in winter, moisture is not easily by rapid evaporation, be added with slag micropowder and antifreezing agent simultaneously, the concrete brick made by it is made to have good cold tolerance, not easily by bursting by freezing.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the embodiment of the present invention, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the schema of preparation method one preferred embodiment of cold-resistant concrete brick of the present invention.
Embodiment
Be clearly and completely described to the technical scheme in the embodiment of the present invention below, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
As shown in Figure 1, the embodiment of the present invention comprises:
A preparation method for cold-resistant concrete brick, comprises the following steps:
A, cement, sandstone, flyash and water proportionally coordinated and puts into stirrer and carry out stirring and smashing, stir 10 minutes;
B, in stirrer, put into broken sand, water reducer, slag micropowder and antifreezing agent again and stir, stir and form absorption layer mixture after 30 minutes;
C, take out absorption layer mixture with spades and put into brick pressing machine equipment compression moulding concrete brick;
D, compression moulding concrete brick placed in curing room and carries out maintenance 1-3 days, make cold-resistant concrete brick.
In above-mentioned, the raw material in described step a and b and mass percent are:
Cement 20-50%;
Sandstone 10-15%;
Broken husky 15-25%;
Flyash 10%;
Water reducer 2-3%;
Slag micropowder 1%;
Antifreezing agent 6%;
Water 6-20%.
Further, adopt the normal vapor cure of pressure in the curing room in described step c, the pressure in curing room is 0-2.0Ba, can accelerate the efficiency making cold-resistant solidifying cob brick.
Wherein, described antifreezing agent is ethylene glycol.Antifreezing agent, also known as antifreezing agent, is that a class joins in other liquid (being generally water) to reduce its freezing point, to improve the material of freezing tolerance.It also has the effect of dissolving ice crystal and stoping ice crystal to be grown up.The feature of excellent antifreezing agent should cheap, chemical stability is good, non-corrosiveness, nonflammable, low toxicity, low foam, odorless and viscosity is less.The antifreezing agent of general use has methyl alcohol, ethanol, ethylene glycol, water-soluble amide and calcium chloride, salt solution etc.Wherein the cold tolerance of ethylene glycol is excellent, is topmost antifreezing agent.The aqueous solution such as: ethylene glycol content is 40%(quality), freezing point is-24 DEG C; And containing ethylene glycol 58%(quality) the aqueous solution, its freezing point is-48 DEG C.
