Abstract
The utility model discloses a rejects autoclaved aerated concrete building block, which comprises a cuboid building block body, wherein the dimensions of the building block body are 600mm*250mm*100mm; and enclosed millipores of which the diameters are 0.5-2 millimeters are formed inside the building block body, are independent of one another, and are uniformly distributed in the building block body. The rejects autoclaved aerated concrete building block has high sound insulation performance, can insulate sound of 30-52 dB on a wall body according to different wall body thicknesses and surface treatment modes, and is a good sound-absorbing material simultaneously.
Description
Technical field
The utility model relates to a kind of rejects Autoclaved aerated concrete blocks.
Background technology
Build a resource-conserving and environment-friendly society, builing industry must be researched and developed the building energy conservation product.The air-entrained concrete building block product is to belong to one of new wall material, but at present people are not enough to its understanding, and the building use amount is little, and by gas concrete is further studied, the materials for wall of producing high-quality more is extremely urgent.Gas concrete be a kind of be primary raw material with siliceous materials such as flyash, quartz sands, lime, cement are calcareous cementitious material, aluminium powder is a blowing agent,, slip preparation levigate through raw material, utilize the chemical reaction of aluminium powder under alkaline environment, produce hydrogen, slip is expanded, and under the steam press maintenance condition, form a kind of be the silicate material of feature with the porous, be a kind of novel wall material with lightweight, insulation, heat-proof quality.Show that according to interrelated data and experiment the drying shrinkage value of Autoclaved aerated concrete blocks increases and increases with moisture content.Autoclaved aerated concrete blocks suction is led slowly wetly first quick and back slow, and building block pore major part is the pore of " ink bottle " structure, and having only small part is that the pore tripe of water evaporates formation is young greatly, and capillarity is poor.When steam pressurized foam concrete does not also have intensity after getting angry by the steel wire excision forming, the loose powder of the fish scale shape that its cut surface has one deck to be taken out of by steel wire, these powders can play certain buffer action when facing, influence the good adhesion of facing.The block surfaces small pore that gathers in addition, the sand grains in the motar can not enter these apertures, thereby has weakened the adhered area of mortar and basic unit, on the other hand, the less and unfavorable adhesion of masonry surfacing of aerated concrete masonry mortar joint groove.Tension, the shear strength of Autoclaved aerated concrete blocks are low.
The utility model content
The purpose of this utility model provides a kind of rejects Autoclaved aerated concrete blocks, and sound insulation value has very big raising.
The utility model is that the technical scheme that its technical problem of solution is adopted is,
A kind of rejects Autoclaved aerated concrete blocks comprises a building block body, and described building block body is a rectangular shape, its dimensions is 600mm * 250mm * 100mm, building block body inside is provided with the closed porosity that diameter is 0.5mm～2mm, and described micropore is independent mutually, evenly is arranged in the building block body.
The beneficial effects of the utility model are, the sound insulation value of this rejects Autoclaved aerated concrete blocks is good, different according to thickness of wall body and surface treatment mode, but 30～52 decibels of body of wall sound insulations, and simultaneously, it also is a kind of good sound absorption material.
Description of drawings
Fig. 1 is the structural representation of a kind of rejects Autoclaved aerated concrete blocks that the utility model proposes.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose with effect is easy to understand, below in conjunction with illustrating and specific embodiment, further set forth the utility model.
As shown in Figure 1, a kind of rejects Autoclaved aerated concrete blocks that the utility model proposes, comprise a building block body, described building block body is a rectangular shape, its dimensions is 600mm * 250mm * 100mm, building block body inside is provided with the closed porosity that diameter is 0.5mm～2mm, and described micropore is independent mutually, evenly is arranged in the building block body.
The sound insulation value of this rejects Autoclaved aerated concrete blocks is good, different according to thickness of wall body and surface treatment mode, but 30～52 decibels of body of wall sound insulations, and simultaneously, it also is a kind of good sound absorption material.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the manual just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
