Gas concrete (gas-concrete blocks) is the material which is getting more and more popular in construction. It is employed for building private houses, various commercial property, schools, hospitals and high-rise constructions.
Gas-concrete mixture contains the following components: cement, sand, drinking/technical water and chemical additives. We shall speak about each ingredient in more detail further.
Cement of almost any type can be used for production of gas concrete. However, please consider that every concrete plant will have a different formula of the mix. The production technology provides for making a formula of gas-concrete mix for particular type of cement.
1 m3 of gas concrete will require about 300 kg of cement.
In most cases sand is used as a filler (maximum fraction of sand is 2 mm). However in some cases the furnace dust from HES, dolomite powder etc. can be used.
1 m3 of gas concrete will require about 200-400 kg of sand.
Any drinking water can be used in production. Should you opt for technical water, choose soft or moderately hard non-saline water.
1 м3 of gas concrete will require about 250-300 liters of water.
This component acts as a gasifier.
1 м3 of gas concrete will require about 500 grams of aluminum powder.
Caustic soda (sodium hydroxide) is used as a hardening accelerator for gas concrete. Therefore, the hardening rate of gas-concrete mix increases considerably.
The required amount of caustic soda is 0,2-2 kg for 1 m3
The production of gas-concrete blocks is simple and does not require high expenses. Therefore, this niche suits everyone who plans to launch a business.
As you see, the production of gas concrete is a simple process. Moreover, as soon as you purchase the equipment you will get the detailed manual describing the whole production technology in simple terms.
