Description
Technical field
The invention discloses a kind of preparation methods of waterproof pressure-resistant type autoclave aerated concrete building block, belong to construction material skill
Art field.
Background technique
With wideling popularize for energy-saving and emission-reduction policy, develop non-stick great soil group, energy saving and environment friendly novel wall material replaces
Clay brick, it has also become the inexorable trend of wall material reform and development.The popularization of new wall material will bring huge income, effectively push
The development of energy-saving and emission-reduction work.
One of important species as novel wall material, autoclave aerated concrete building block and traditional clay fired brick phase
Than with good effect of heat insulation, fire protecting performance is good, sound insulation, many merits such as light, environmentally friendly.It can be not only used for filling out for frame structure
Wall is filled, and can be used for the bearing wall of load-carrying members.Meanwhile it is also the greening building energy saving material vigorously advocated in recent years
Material is widely applied in the area such as cold hot summer and warm winter zone, Xia Redong, plays the role of important support to construction industry.However, air entrained concrete
Building block volume deformation coefficient is bigger than normal, low strength, water absorption rate are big, and when building into wall, crack easily occurs in wall, and coat of plaster is easy
Large area cracking, hollowing and obscission are generated, apparent brittleness is shown, hinders steam pressurized coagulation to a certain extent
The further application and popularization of earth building blocks.
Fiber is just widely used from 20th century traditional general as a kind of good cement matrix reinforcing material
In logical concrete product, correlation theory has also obtained more sufficient and in-depth study.However due to steam-pressing aero-concrete
During industrialization production, general to carry out excision forming to the air entrained concrete after initial set using steel wire, incorporation is excessive for building block
Fiber the cutting of air entrained concrete can be influenced so that fiber applied in steam-pressing aero-concrete it is fewer,
Correlative study is also opposite to be lacked.Glass fibre has high-intensitive, Gao Mo as one of kinds of fibers common in construction material
Amount, it is low stretch, high temperature resistant and the features such as good chemical stability, and corn stalk fiber also have it is cheapness, come extensively
The many merits such as source property, environment friendly, draw ratio are big and specific strength is high, for this purpose, there is researcher respectively by two kinds of volume volumes
Corn stalk fiber and glass fibre incorporation autoclave aerated concrete building block in, study its resistance to compression, Split-tension of Rolled mechanical property,
It can make moderate progress to its Brittleness.
The application of new wall material also produces the leakage problems of a little negative effect, especially walling.The leakage of walling with
Its permeance property is closely related, walling by rainwater the effects of under can permeate, the media such as various harmful circulating waters, solution
Penetrated by material hole internal, will cause material corrosion, the decline of loosely organized and compactness, eventually lead to material heat preservation and
The decline of endurance quality brings dangerous and discomfort to resident.Therefore, the quality of walling anti-permeability performance will directly influence
The durability of building structure.There is scholar to study this, and has invented a kind of steam pressure containing industrial solid castoff and added
Gas concrete segment and preparation method thereof, weight percent composition are as follows: base-material: 35%~47%, magnesium chloride solution: 35%~
39%, magnesia: 10%~15%, bonding agent: 2%~5%, industrial hydrogen peroxide: 2%~3%, lanthanide rare: 1%~2%, additive:
5%~7%.Autoclave aerated concrete building block of the invention have fire prevention, waterproof, Anti-moth-eating, light-weight, resistance to compression bending resistance, intensity height,
Not the advantages that long moss, raw material ratio composition determines that its waterproof and the performance of Anti-moth-eating, compression strength are greater than
53Mpa, bending strength are greater than 80Mpa；In addition, effective use industrial solid castoff, waste utilization is environmental, really
Turn waste into wealth.But traditional autoclave aerated concrete building block is also easy to produce cracking since internal void is more, leads to the anti-of product
Compressive Strength decline, and due to the presence of a large amount of holes, so that the waterproofness of product be made to substantially reduce, therefore also need to grind it
Study carefully.
