1.Introduction
China famous brand building block making machine,concrete block plant
AAC blocks are made of fly ash,lime,cement,gypsum and aluminium powder,and with the procedures of crush-ing,measuring,mixing,pouring,autoclaving and cutting. it can be made into many kinds of bricks for example:600×200×100,80×80×180,240×115×53,600×200×125),AAC block has advantages of extremely light weight,excellent thermal insulation,heat insulation,energy conservation,waste recycling,convenience.As a new building material,AAC is emphatically promoted by the word,in the future,they will replace the Clay brick completely. AAC block and hollow block making latest autoclaves
2.Advantage of AAC block/lightweight block
(1)light weight
Areated concrete density is usually 400-700kg/m3,(according the market in produce ),same as 1/3 of clay brick and 1/5 common concrete.So use the Light brick can reduce the weight of the build more,and also reduce the beam of roof and pillar press best.then you can see,it can save the material and cost,it also fighting shaking.
(2) keeping temperature
It has many are porous,the delivery hearting coefficient is 0.9-0.22W/(mk),the same as 1/4 or 1/5 of clay brick,so it is best materials now in the world.There are many kinds material,have lowest waste.
(3)High Strength
High pressure steam-curing autoclaving process gives AAC unmatchable strength to weight ratio, higher than even M150 concrete and far exceeds the Indian Building code requirements
(4)Cost saving
Being lightweight AAC drastically reduces the dead weight of building, resulting into reduction in steel (up to 27%) and cement (up to 20%) structural cost saving.Being 8 times the size of a clay brick, AAC wall construction involves 1/3 the joints, thus an overall mortar saving up to 66%
(5)Fireproof
Most of the major raw materials is inorganic materials, so it has good fire resistance, and do not emit harmful gases when meet fire. Fire 650 degrees, as a refractory material, the thick up of 90mm walls can reach to 245 minutes fire resistance, 300mm thick up wall can reach to 520 minutes fire resistance.
(6)Sound insulation
Due to a unique porous structure, so it has a sound absorption capacity. The sound absorption capacity can reach of 10mm thick wall up to 41 db.
(7)Permeability
Result of material by the composition of many independent small pores, the moisture absorption is slow, in the volume of absorbent is 5 times of clay saturation do. When used in the bathroom, the wall can be treated to interface directly paste tiles.
(8)Anti-seismic
The same building structure, improve the two seismic than the brick level.
(9)Green
Manufacturing, transportation, all use the process of pollution, to protect arable land, saving energy, is one kind of a green building material.
(10)Shortcut
It has good machinability, can be sawed, planed, drilled, nailed, and available appropriate as bonding of adhesive material, so create favorable conditions for building construction.
(11)Economies
An integrated lower cost than using more than 5% of solid clay bricks, and can increase the usable area, greatly enhance the utilization of floor space.
