Advantages of AAC project aac block
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
It 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.
AAC project raw material
1 Product weight is according to 600kg/m3 to control.
2 annual capacity 300,000M3.
3 set raw material proportion: cement 6.5%, raw lime 23%, flyash 68%, gypsum 3%, aluminum paste powder 350g/M3.
4 water and material rate 0.631
5 one mould product 2.88M3
6 Casting slurry cycle time 5-6 minutes, cut cycle time 5 minutes.
7 casting slurry temperature 38-42 degree
8 body quiet stop. Time is 1.5-2.5hours, temperature 50-90 degree, after quiet stop body strength is 0.15-0.18Mpa
9 Steam curing cycle time, come in and out autoclave about 0.5hour, steam curing cycle time about is 6 hours/1.6Mpa, total 6.5 hours.

Main features of Hongfa AAC project
1,Agglomerate lime is firstly crushed by jaw crusher, and then the granule lime is milled by energy-saving mill.
2,Mixing the fine grinding sands and the waste slurry for the slurry can improves effectively the stability of the slurry.
3,The slurry and powder are weighed by electronic measurement. The measurement and pouring of batching plant are controlled by central control room.
4,The pouring method adopts fixed point pouring.
5,It chooses the JQF 6.0 step by step cutting machine (Made in China). The maximum cutting size is 6.0×1.2×0.6m and the capacity of the cutting machine is about 400,000 m3 per year. The cutting precision reaches the China advanced level among the same size.
6,The autoclave kettle adopts 2 upward-acting doors to decrease
the time of the brick in and out of the autoclave and saves construction areas.
7,Using the integrated process layout, it is conductive to building warm insulate and automatic control of the line. At the same time, it reduces the cost of construction.
8,Using hydraulic transport system instead of travelling crane can improve the stability of the system and save the procedure of application for inspection.
9,The waste on the bottom is cleaned by the hanger with cleaner and then sent to the autoclave kettle for autoclaved maintenance to realize no hard waste for production.
10,Comprehensive utilization of the waste material, waste water, waste gas and rain water helps make full use of the source and reduce emissions.
11,In order to simplify processing and reduce the cost of production, manual work is needed to clean and oil the molds.
