AAC Block Decorative Concrete Wall Block Manufacturer Selling

Product Description

 

Introduction of Autoclave Aerated Concrete (AAC)Block

 

Autoclave Aerated concrete (AAC)block is a new type of lightweight and porous building material widely used as high rise building reinforced concrete frame structure filling materials .

It has features of Lightweight, high intensity ,heat preservation, heat insulation, energy saving, Waste utilization, environmentally friendly construction, convenient to use.It has been widely valued by the construction industry all over the world and has become a building material that many countries promote and develop .

The output of the AAC block production line produced by our factory is 2.5,10,15,200.3 million square meters per year.

 

Raw Materials of Autoclave Aerated Concrete Block

 

It uses Siliceous materials (such as fly ash, sand and silicon-containing tailing) and calcium materials (such as gypsum, lime ,cement) as main raw materials, using aluminum powder as a foaming agent, which is made by crushing,metering,mixing, pouring, curing ,cutting,autoclaving and packing.

 

Working Principle of Autoclave Aerated Concrete Block Making

The structure of aeration block is formed by physical and chemical reactions between slurries. Silica materials (sand, fly ash and silica-containing tailings, etc.) and calcareous materials (lime, cement) are used as main raw materials, and aerator (aluminium powder) is added to mix with water. Pores are formed by chemical reactions. The chemical reaction of slurry gasification in fly ash aerated coagulant slurry is initiated by mixing and pouring raw materials. When fly ash slurry, cement, quicklime, aluminium powder, water and other additives are added to the mixer, the hydration of cement and quicklime occurs.Ca(OH)2is precipitated during cement hydration, so the liquid phase in aerated concrete slurry presents alkali and quickly turns into saturated solution (PH value is about 12). Aluminum powder is very easy to interact with alkali solution. Aluminum powder reacts with alkaline saturated solution to produce hydrogen, which seldom dissolves in water, and the volume of hydrogen increases with the increase of temperature (from 0 to 40 degrees C, the volume of hydrogen gas increases). Therefore, the mixture slurry will inevitably expand.

Block forming stage is the process of slurry thickening and condensation. Hydrogen and slurry expansion are always in dynamic equilibrium when aluminium powder reacts with water. The power of slurry expansion is the internal pressure in the bubbles, and the resistance of slurry expansion is the gravity of the upper slurry and the ultimate stress of the slurry, which results in uniform bubbles.

 

Processing flowchart of Autoclave Aerated Concrete Block

 

 

1. Storing and supplying of raw materials

 All raw materials are carried into factory by trucks.Fly ash,sand or lime are gathered in specified raw materials field waiting for using.cements stored in cement warehouse.

Chemicals and aluminum powder are separately kept in chemical warehouse and aluminum warehouse.When used,these raw materials are carried into workshop respectively.

 

2. Processing of  raw materials

Quick lime is sent by vibrating feeder and belt conveyor into jaw crushers to smash. Smashed lime is sent into lime silo by bucket elevator and then is transported into ball mill by screw conveyor. Fined materials are sent into proportion bin by screw conveyor and bucket elevator.Aluminium powder is lifted to second layer and empty into mixer.Then quota water is poured to make aluminium powder into suspension.

 

3. Aerated block Ingredients,Stiring and Casting

Fly ash (or sand or stone powder )and waste slurry are measured in measuring tank.After the measuring and mould in their place,slurry stirring begins.Slurry temperature should reach about 40°-This is technical requiremnents.If the actual temperture doesn’t arrive 40°,vapor is used in the measuring tank to raise temperature.Half or one minutes before casting,aluminium suspension is supposed to be added to the slurry.

 

4. Pre-curing and Cutting Process

Cut model is conveyed to precuring room for gas forming. Room tempreture should range from 50°to 70°.This period lasts one hour and a half totwo hours.(If materials take on geographical advantages,this precuring can be eliminated.  Precured green body together with mould frame will be lifted to cutting station that is covered by autoclave board .After frame detachment,cutting machine do cross-cutting, vertical cutting, face-milling and tip-binding. At the same time, die grid is hanged to recuring cart for manual cleaning and degresing to prepare for the next perfusion. The cutting ready embryois are carried to precuring cart together with die seat, palletizing in two tiers, four pillars between two the tiers, and get into grouping process.When the cutting of body is completed, partial waste materials cut down will be processed into waste material slurry which then will be pumped to the slurry tank located at the topmost story of batching building, after that, add the necessary raw material, then transported into a pulping machine for reuse.

 

 Raw Material Ratio of Autoclave Aerated Concrete Block

 Note:

        Reference:cement is 42.5 Portland or 42.5 common cement
        Aluminum power paste calculate to use according to 600kg/m3
        Remark: the accurate batching rate is adjustable according to the raw material locally.
