Description
Technical field
The present invention relates to a kind of body of wall constructing technology, belong to architectural and civil engineering field, relate more specifically to a kind of constructional method from fermentation type Cement for walls mixed mortar and this Cement for walls mixed mortar.
Background technology
Traditional construction material sintered clay brick not only consumes a large amount of cultivated land resources and the energy, also creates serious environmental pollution and destruction, forbids firing and using sintered clay brick with regard to expressly providing as far back as build in house No. 295 literary compositions in 1999.For the purpose of built environment friendly, conservation-minded society, materials for wall is after going through innovation decades, and novel wall material, by spread, is in the flourish stage.
Air-entrained concrete building block is as the type material constructing non-bearing wall body, it is one of most widely used material, turnout with every year on average 20% speed increment, it is a kind of light porous, heat insulating, fire-proof and thermal-insulation, plasticity-are strong, shock resistance good and ultimate compression strength is large excellent construction material.But, due to the instability of air-entrained concrete building block sole mass, the utilisation technology specification imperfection of materials for wall, add and do not have strictly to construct according to the characteristic of new concrete materials for wall, therefore in the process of walling big area innovation, there is construction quality common fault, wherein wall crazing and the leakage problems that causes thus have become the main aspect in common quality defect, are also that the people is to one of focus of building quality complain.
The main factor that air-entrained concrete building block produces crack is exactly temperature, shrinkage crack caused by difference variation, its mechanism of production is: each face wall body is built by laying bricks or stones by the little masonry of polylith to form, when ambient air temperature declines, monolithic masonry has contraction in various degree, and the shrinkage value of overall metope is just larger.Meanwhile outside coat of plaster is also in contraction, but the intensity of shrinking is less, causes systolic dyssynchrony inside and outside body of wall and produces delamination, causing crack to produce.And when not full, the outside coat of plaster insufficient strength of mortar seam at a certain position of overall metope, this cracking will be more obvious.
The form in the crack that wall of aerated concrete block produces is varied, some or even multiple crack form are also deposited, with the experience of contriver's working more than 20 years, by the collection of on the-spot investigation and documents and materials, find that aerated concrete block wall crack main manifestations is following several form:
(1) zigzag cracks: have two kinds, the first is wall plastering facial cleft seam, and this crack is present in body of wall big area position, crack form be horizontal, skewed crossing is irregular, greatly, the amount of doing over again is large for influence area; The second is the crack that building block cutting fluting produces, and due to body of wall inevitably burying hydroelectric line underground, switch box switch, the components such as socket, very easily produce zigzag cracks in component surrounding or along pipe laying position.
(2) horizontal slit: within appearing at the upper and lower scope of top layer roof boarding, body of wall all has in length and breadth.
(3) Vertical Cracks: be generally present in body of wall infilled wall and concrete column or shear wall junction, the through overall height of this seam and stitch wide larger.
(4) all edge cracks: generally appear at junction or sash surrounding that building block and body of wall inlay clay brick.
(5) diagonal crack: positive splayed crack, generally appears on the window corner on buildings top, wall between windows, windowsill wall, exterior wall and interior wall; Herringbone crack, the window corner of small part buildings bottom, wall between windows, windowsill wall there will be this crack, and its form is with positive splayed crack.
Although gas concrete is subject to the favor in market as building material.But wall of aerated concrete block easily produces crack and is still one and allows people perplex and the technical problem of complexity.Even if the principle in wall of aerated concrete block generation crack, type and reason are all known, but in practice of construction, the preventive measure effect taked for crack is very poor, has a strong impact on again the outward appearance of building after repairing.
At present, although technician both domestic and external has done for the material behavior of air-entrained concrete building block the work that many dedicated mortars are developed, the standard of mortar special for gas concrete building block has even been formulated in each place., because air-entrained concrete building block is a kind of silicate building material with the vesicular structure of high dispersive, Young's modulus and the real non-easy thing of shrinkage value of this matrix material be determined.Develop a kind of air-entrained concrete building block that adapts to and build needs by laying bricks or stones, good fluidity, visco-plasticity can good, mortars that water retention property is strong, can reduce even solve its wall body slit problem with this, extremely difficult especially.Still more, the operating technique that can control the generation of aerated concrete block work crack is not very well had at present yet.
