Description

A kind of sintering shale perforated brick

Technical field

The invention belongs to the construction material technical field, particularly relate to a kind of sintering shale perforated brick.

Background technology

At present, the construction material of widespread use mainly is a sintered clay brick in the domestic construction, the hollow fragment of brick of concrete small size, aerated-block, gypsum sheet material ability; And use clay brick will consume a large amount of non-renewable soil resources with fixed attention, and reducing agricultural cultivated area, government department is to limit its use under construction; And the concrete small size hollow brick is big because of its unit weight, and construction is complicated, influences secondary decoration; Be easy to generate shrinkage crack, shortcoming such as thermal property difference and influence its application under construction.

Along with the progress and the development of society, the building trade development is swift and violent, and the demand of body of wall increases rapidly; And since 08 year begins to forbid common brick, there has been bigger imbalance between supply and demand, based on above-mentioned situation always; A lot of regional mass production are suitable for the concrete perforated brick and the perforated brick of construction wall; Utilize the perforated brick masonry panel to have from advantages such as heavy and light, sound-insulating performance are good, the density of perforated brick is lower by about 30 than common brick, because brick itself has a lot of holes; Thereby reduced the thermal conduction of brick, and then reach heat insulation effect; Adopt the perforated brick of 150mm to be equivalent to the thick common brick of 190mm; The reduced thickness of porous brick wall 1/5; Approximating increases floor area of building 2%～3%, practices thrift brick earth 20%, and perforated brick is bigger than traditional clay brick thickness; Fill up mortar joint with mortar 20%～30% thereby reduced, also increased the folding strength of brick simultaneously.

Various perforated brick are arranged in the market; Mostly utilize shale and coal gangue to carry out the fragment of brick of high-temperature firing for raw material; But the how empty brick of shale on process investigation and the test marketing does not mostly meet GB13544-2000 " sintered perforated brick " standard or the production cycle is long; Especially in the bigger area of temperature contrast, its major cause proportion of raw materials is unreasonable to form with unreasonable causing of sintering technology.

Summary of the invention

The present invention provides a kind of product percent of pass height, the well behaved sintering shale perforated brick that meets industry standard for solving the technical problem that exists in the known technology.

The technical scheme that the present invention takes for the technical problem that exists in the solution known technology is:

A kind of sintering shale perforated brick is characterized in that: the how empty brick of said shale mainly comprises shale, coal gangue and sticker, and mark is got 3～4 parts in shale by weight, 4～5 parts of coal gangues, 2 parts of stickers.

The present invention can also adopt following technical measures:

Said sticker mainly comprises cement, colloid powder, rises profit soil and water; Get 3 parts of cement by the weight fraction of sticker; 3 parts in colloid powder, rise 3 parts in profit soil, 1 part in water.

Advantage and positively effect that the present invention has are: because the present invention adopts technique scheme; That the how empty brick of produced shale not only has is energy-conservation, the advantage of heavy and light, sound insulation, insulation, fire prevention, good pressure-resistant performance; And the temperature difference that the shale porous brick that is made of the present invention uses is bigger; Area such as cold, hot summer and warm winter zone of severe cold, cold, Xia Redong no matter; In preparation during perforated brick of the present invention, basis, this area personnel are to different areas, can adopt the demands of different such as heat insulation, insulation of different weight proportions to satisfy, to adapt to various places.
