Description
Technical field
The present invention relates to a kind of Crack-resistance Front Mortar dry mash, relate in particular to a kind of low-cost Crack-resistance Front Mortar dry mash that utilizes steam pressure sand aerated concrete waste material to prepare.
Background technology
Steam pressure sand aerated concrete is a kind of novel building walling with wall self-insulation, its technology started from before 100 years, mainly take cement, lime, gypsum, aluminium powder and sand as raw material, through starting material preparations, batching cast, rest get angry, the operation such as base substrate cutting, steam press maintenance, storage of finished products makes.Steam pressure sand aerated concrete sharpest edges economize the land resource exactly, need not waste a large amount of arable lands, the source of raw material very extensively; And have extraordinary can working ability, heat insulation, insulated capacity and processing characteristics, can saw by Bao.Along with the continuous propelling of walling innovation work, steam pressure sand aerated concrete block has been used in a large scale gradually in construction work.
Along with steam pressure sand aerated concrete application extensively, in process of production, cutting waste material, carrying waste material and unacceptable product waste material total amount are also increasing, stack nowhere, without transport ，Gei enterprise and cause very big puzzlement, to environment, bring pollution.At present, steam pressure sand aerated concrete waste material utilizes technology to mainly contain (1) waste material oven dry is mixed with certain mass percent proportioning with after dehydrated gyp-or dihydrate gypsum calcining, and grinding in ball mill, makes swelling agent; This swelling agent is mixed with silicate cement, make expansive cement; (2) by waste muck, filamentary material, short-term strength cement, the water-soluble binder aqueous solution and other industrial waste, make gas concrete waste muck body of wall; (3) crust and scrap body material are made to raw material, adjust its water content, mix the subsidiary material such as colorant, aggregate, enter mould (reinforcement or not reinforcement) moulding, again through hydrothermal curing, can be made into closely knit (or arrangement of reinforcement) silicate hydrochlorate concrete product and compacting silicate tile material product, if carry out surface treatment after hydrothermal curing, also can be made into silicate terrazzo product, floor file and paste wall face brick of all kinds.
But above technology cannot local use waste material, and waste utilization rate is lower, waste material utilizes technology imperfection, can produce secondary pollution, so its marketing exists difficulty.How dealing carefully with, effectively utilize steam pressure sand aerated concrete waste material and obtaining higher social benefit, ecological benefits and economic benefit is problem demanding prompt solution.
Summary of the invention
The object of this invention is to provide a kind of Crack-resistance Front Mortar dry mash based on steam pressure sand aerated concrete waste material, gained Crack-resistance Front Mortar dry mash can directly apply to wall self-insulation system.
To achieve the above object of the invention, the technical solution used in the present invention is:

0.01～0.02 part of auxiliary agent
Wherein, the multipolymer that rubber powder is ethylene/vinyl acetate; Anti-crack fiber is polypropylene fibre; Auxiliary agent is naphthalene water reducer.
The multipolymer that in the present invention, rubber powder is ethylene/vinyl acetate is re-dispersible glue powder; Methylcellulose gum is construction industry MC powder; Cement is that strength grade is 42.5 silicate cement; Steam pressure sand aerated concrete waste material is the steam pressure sand aerated concrete waste material producing in waste product in steam pressure sand aerated concrete production process or building waste.
The present invention's naphthalene water reducer used belongs to prior art, and those skilled in the art can select voluntarily according to product.
The invention also discloses the preparation method of the above-mentioned Crack-resistance Front Mortar dry mash based on steam pressure sand aerated concrete waste material, being specially is first that steam pressure sand aerated concrete waste material powder is standby by steam pressure sand aerated concrete waste material grinding; Then according to the ratio of each component, steam pressure sand aerated concrete waste material powder, cement, methylcellulose gum, rubber powder, anti-crack fiber and auxiliary agent are added in powder mixer and mixed successively, prepare the described Crack-resistance Front Mortar dry mash based on steam pressure sand aerated concrete waste material.
In technique scheme, milling equipment is ball mill, and grinding process comprises fragmentation, grinding, screening; The particle diameter of gained steam pressure sand aerated concrete waste material powder is 60～120 orders.
Because technique scheme is used, the present invention compared with prior art has following advantages:
1. the present invention utilizes steam pressure sand aerated concrete waste material to prepare Crack-resistance Front Mortar dry mash first, effectively reduce dry mortar powder cost, the product of exploitation can be as wall self-insulation starting material, on the spot for building supports the use, economize on resources, turn waste into wealth, can promote the development of Building Energy-saving Work;
2. preparation method disclosed by the invention is simple, non-secondary pollution, and raw material sources are extensive, are suitable for suitability for industrialized production.
