Description

The preparation method of brick is made using lime stone by-product
Technical field
The present invention relates to a kind of building brick, the preparation method that brick is made using lime stone by-product is particularly belonged to.
Background technology
In the recovery process of limestone mine, because containing soil in ore, in order to obtain with certain grain size and concentrate The lime stone finished product mine of grade often will adopt the lime stone raw ore to get off to liter and carry out brokenly the processes such as stone rate, screening, Shen Kuang, about There is the lime stone by-product of raw ore yield 5~10% or so to generate, these byproduct compounds are also contained certain based on lime stone The ingredients such as the soil of amount.These by-products can only heap there are by-product library, not only occupy land resource, environment also resulted in Certain harm.In order to ensure the safe operation in by-product library, it is also necessary to put into a large amount of human and material resources it is monitored with It safeguards.
There are two approach for the utilization of lime stone by-product, first, increasing ore dressing dynamics, improve the rate of recovery of concentrate, reduce secondary The yield of product, second is that isolate the particle of+0.5mm in lime stone by-product, as building sand apply building concrete, Building mortar etc., there are also mines to do concrete brick with above-mentioned building concrete, building mortar.But existing lime stone By-product utilized approach has the following problems：Improve by-product the rate of recovery and extraction by-product coarse granule after, still have 50% with On particulate by-product generate, wherein clay content is up to 20~60%；Generally can only heap there are by-product libraries, it is difficult to utilize.
A small amount of lime stone by-product is applied as building sand in building concrete, building mortar, of high cost, And remaining byproduct emission, stockpiling problem can not be fully solved.
Invention content
It is an object of the invention to solve the deficiencies of current lime stone by-product utilized rate is low, stockpiling is serious, one kind is provided Lime stone by-product utilized rate may be up to 90% or more until all, without land occupation resource, realization lime stone by-product Make building brick and ingredient and the simple lime stone by-product brick of production method and preparation method thereof.
Realize the technical solution of above-mentioned purpose：A kind of lime stone by-product brick, its component and weight percent are：Lime Stone by-product：70~90%, curing agent：10~15%.
It is：It is this R of 0~30% sandstone aggregates or flyash to be additionally added weight percent.
It is：The curing agent is sarsaparilla curing agent or HAS curing agent or HEC consolidating agents.
Prepare a kind of method of lime stone by-product brick, step：
(1) lime stone by-product is carried out dehydrating, the water content of control lime stone by-product is≤15%；
(2) it is dehydrated again, and the water content for controlling lime stone stone by-product is<5%；
(3) impurity removing uses sieve to remove the block of granularity >=5 millimeter,
(4) mixing is carried out, mixed clay content control is the 20~50% of total weight；
(5) the lime stone by-product of granularity≤5 millimeter is uniformly mixed with curing agent；
(6) add water and stir evenly, the moisture content for controlling its mixed raw material is 6~l1%；
(7) it carries out brickmaking and conserves.
Compared with prior art, the present invention not only expanding the raw material sources problem of brickmaking, but also make lime stone by-product Brick maximizes the use, and solves the problems, such as windrow land occupation resource, and the building brick made meets Gu Jia marks Standard, simple for process, quality control is stablized, and production cost is low.
