Abstract
The present invention is a kind of preparation method of river sand brick, it is characterized by: 1) by river sand 40-80%, quick lime 10-30%, cement 5-15%, flyash 5-15%, another plus cement amount 0.6-1.2% hardening agent are added suitable quantity of water and stir evenly, amount of water be subject to pinch it is agglomerating landing dissipate, mixing time be no less than one minute；2) it is sent into brickmaking machine and is pressed into brick, pressing pressure 180T/m2；3) it forms, molding brick is sent into greenhouse and is formed, and guarantee not drenched by water in 6-10 hours, it is primary every water drenching in 3 hours later, and drench, the humidity in greenhouse is 5-10 degree, and temperature is 20-35 degree, is divulged information, and shaping period is 7 days or so.The present invention is since the raw material used is river sands and industrial residue; soil is not taken, does not destroy vegetation; it is not sintered in process of production, saves a large amount of fuel; atmosphere is not polluted; various waste residues are also largely utilized, positive protective effect are played to urban environment, and with short production cycle; at low cost, intensity is high.
Description
Technical field
The present invention relates to building material technical field, specifically a kind of preparation method of river sand brick.
Background technique
Existing fired brick (common brick) needs a large amount of coal in process of production, not only waste of energy, but also environmental pollution is serious.
In the harmfulness of its pollution, national relevant policies limit the production of this kind of brick, and it is non-burning brick to propose prosperous production.It is unburned
The production of brick generally uses sand and cement etc. as raw material, but the brick specific gravity produced is too big, brings biggish ask to construction industry
Topic.
Summary of the invention
The object of the present invention is to provide one kind can save soil resource in process of production, saves the energy, protects environment, at
This is low, brick body resistance to compression, High anti bending strength and river sand brick for reducing brick specific gravity and preparation method thereof.
The present invention is implemented as follows: the present invention utilizes basic material river sand, quick lime, flyash is added a certain amount of
Cement forms ultra dense state under a certain pressure with proper amount of hardening agent, fills cement therein with strength agents and river sand
Divide mixing, gelling silica and active material occur chemical reaction and form highdensity reality building block, by moisturizing, heat preservation under greenhouse
Equal maintenance measures form.Concrete scheme is as follows:
River sand 40-80%, quick lime 10-30%, cement 5-15%, flyash 5-15% separately add cement amount 0.6-1.2%
Hardening agent, above-mentioned raw materials are added water and stirred uniformly, are pressed into brick through brick machine.
The preparation method of above-mentioned river sand brick is:
1) by river sand 40-80%, quick lime 10-30%, cement 5-15%, flyash 5-15%, separately add cement amount 0.6-
1.2% hardening agent, be added suitable quantity of water stir evenly, amount of water be subject to pinch it is agglomerating landing dissipate, mixing time be no less than one
Minute；
2) it is sent into brickmaking machine and is pressed into brick, pressing pressure 180T/m2；
3) form, molding brick be sent into greenhouse and be formed, and guarantee 6-10 hour it is interior do not drenched by water, later every
Water drenching in 3 hours is primary, and drenches, and the humidity in greenhouse is 5-10 degree, and temperature is 20-35 degree, divulges information, and shaping period is 7 days left sides
It is right.
The present invention has the positive effect that compared with the prior art:
1, the present invention is since the raw material used is river sands and industrial residue, and not duty soil does not destroy vegetation, in production process
In be not sintered, save a large amount of fuel, atmosphere is not polluted, various waste residues is also largely utilized, product is played to urban environment
The protective effect of pole.
2, of the invention since brick body can increase stacking, it is not take up the land resource of a large amount of preciousness；Its simple process, easily
In operation, general staff can be operated.
3, the present invention is at low cost in due to short production cycle, can lower 50% than price with ordinary red brick, can reduce building
Cost.
4, resistance to compression, High anti bending strength of the invention compared with traditional common brick, water absorption rate is low, can be big industrial workshop
Chimney provides high-intensitive brick body.
Specific embodiment
Embodiment 1:

Be subject to pinch it is agglomerating landing dissipate, mixing time be one minute；
2) it is sent into brickmaking machine and is pressed into brick, pressing pressure 180T/m2；
3) form, molding brick be sent into greenhouse and be formed, and guarantee 6-10 hour it is interior do not drenched by water, later every
Water drenching in 3 hours is primary, and drenches, and inner greenhouse ground humidity is 5-10 degree, and temperature is 20 degree or so, is divulged information, and shaping period is 7 days left sides
It is right.
Embodiment 2:
River sand brick composition of raw materials are as follows: water is separately added in river sand 55%, quick lime 25%, 325# cement 8%, flyash 12%
The early strength water-reducing agent of mud amount 1.2% is as hardening agent.
Above-mentioned raw materials are prepared according to the following steps:
1) duty river sand, quick lime, 325# cement, flyash and early strength water-reducing agent add water and stir according to the above ratio, amount of water
Be subject to pinch it is agglomerating landing dissipate, mixing time be one minute；
