Brief introduction
German technology light weight sand aac block making machine from Hongfa factory
AAC (Autoclaved aerated concrete) block Main raw materials of AAC are siliceous material (sand, fly ash and Silicon tailings) and Calcium materials (lime and cement) mixed with foaming agent (aluminum powder). It is the product of light porous silicate through the following processes: batching, mixing, pouring, hardening, cutting, autoclaving and curing etc. Because of large amount of well-distributed tiny pores after foaming, it is named autoclaved aerated concrete.
AAC Classification : In general, it can be classified according to the types of raw materials, manufacture process and functions. Based on the shape of AAC products, it can be divided into: AAC blocks and AAC panels. It is a revolutionary material offering an unique combination of high durability and strength, low weight, excellent heat insulation, fire resistant, noise absorption, unprecedented build ability and superior ecological green features. In China, AAC is one of the light wall materials which was popularized and applied at the earliest and the most widely.
Autoclaved Aerated Concrete (AAC) has been used all over the world for decades, firstly produced in terms of industrial means in Sweden in 1923. It is a unique building concept, available in today's market with innumerable building advantages.
AAC is lightweight concrete that is produced under special circumstances, by adding aluminium paste which creates a porous shape into the mixture of cement, finely grounded quartz sand or flyash, water and limestone. AAC is very firm and the most durable construction material that provides heat insulation by its porous texture, security against earthquakes through its lightweight structure,and safety against fire by its non-flammable quality (Fire Class A1).
AAC building products can be used for all applications including every type of masonry walls, roofs and floors. AAC is largly preferred especially in many developed countries such as all EU countries, USA, Japan, Russia,Australia and all Gulf countries and Kingdom of Saudi Arabia,and most developing countries.
Advantages
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.
keeping temperature
aerated concrete panel has many 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. Also many kinds raw material,have lowest wasteMain Material:coal ash sand waste mine material coal stone,stone dust and other silicon materials.

ALC block (Autoclaved Lightweight Concrete Block) is also called AAC Block (Autoclaved Aerated Concrete Block) which is steel mesh reinforced, lightweight and loadbearing.
Autoclaved Aerated Concrete Block are widely used as external wall panel (exterior wall panel), internal wall panel (interior wall panel), partition wall panel, flooring, roofing, fence, cladding, curtain wall and facade etc.
Autoclaved Aerated Concrete Block are widely used in different kinds of buildings, such as public facilities, industrial constructions, steel structure building, warehouse, workshop, stores, hospitals, hotels, apartments, villas, schools, supermarkets etc.
Autoclaved Aerated Concrete Block can replace traditional precast concrete and clay bricks very well. Also the panels can easily cut, drilled, screwed when installing with fast speed due lightweight and precast.
1. Material dealing process
Put the fly ash or sand into the ball mill to mill via the conveyor belt, after milling, put the slurry into the slurry storage tank by slurry pump.
The lime, cement will convey by conveyor to the dry powder measure scale to scale separately. The slurry convey by slurry pump then to the automatic scale;the power and slurry put into the mixer,pouring into the mould.
After slurry pouring into the mould, put the mould box into the curing room with 50~70℃. After 2-3 hours curing,the blocks become solid
Using reversal crane carry the mould and block to demould on cutting cart. The cutting cart will take the block to level cutting machine,vertical cutting ,two sides cutting,and remove the top waste material.
Finished cutting using semi-product crane carry to the front of autoclave grouped,hoisting machine or dragger will drag steam trolley into autoclave to steam,it need 10-12 hours.
Finished product out of autoclave,with separting machine to separate layer by layer.
Using finished block carry hanger clamp the finished product to package line on wooden pallets,after package, then by forklift transport the finished products to piled yard according to specifications to stack.
It has the advantages from the process:
1. It can realize the mixed grinding to prepare the cementitious material and effectively improve the pouring stability; the flow-tube type pouring stirring can shorten the stirring time and greatly improve the uniformity of stirring.
2. Raw material processing can realize the hydrothermal ball milling process and improve the stability of fly ash and mortar.
3. Staggered batching process. The batching building is divided into two and staggered. It simplifies the layout of equipment and building structure, and meets the requirements of staff space and equipment layout.
4. Integrated layout technology, which arranges the batching, pouring, pre-cultivation, cutting, bottom removal, marshalling and other processes in the same workshop. Uses hydraulic lifting and conveying equipment to separate the walking guide from the main body of the workshop and reduce the height of the workshop. Layout, avoiding dead corners in the building, shortening the return path of waste water and waste slurry, reducing the moving space of operators and improving work efficiency.
