Lightweight concrete brick, also called CLC bricks, is the most modern construction marvel in this century. It is used for the construction of lightweight concrete brick machine. This new age modern method of making construction material is a worldwide phenomenon. It is the most endearing piece of technology evolution.
Gaodetec is one of leading CLC brick manufacturing unit in China offering light weight bricks machinery at a low cost. We also produce foam generator and protein foaming agent. Basic raw material used in manufacturing CLC bricks are sand, cement, fly ash, aggregates of foam and water.
The on-site production set up and process in producing CLC light weight bricks involves dry density parameters to be maintained. It is between 300-600/800-1000/1200-1800kg/m3. The thermal conductivity levels are between 0.16 for 500kg/m3, 0.21 for 800kg/m3 and 0.28 for 1000kg/m3. It consumes least amount of energy with reusable industrial waste also known as fly ash, which is a green product that means free of pollution. The technology used in thermal insulation is foam concrete within a density of 250 – 550kg/m3 in CLC Bricks. This is primarily beneficial in thermal insulation, thus preventing protection from fire hazards in case of fire.
CLC Bricks technology in the production of light weight bricks is initially a mixture of cement, fly ash and water. These three are added and thick slurry is prepared. This is further mixed with protein foaming agent in an ordinary concrete mixer in ambient conditions. The foaming agent is diluted in 40 parts of water. The addition of pre-formed foam creates millions of tiny voids in the light weight brick material. Thus, the name cellular concrete (CLC) has been derived.
The weight of the foam should be stable and not exceed 80 g/l. The containment (or compression) must be as close as possible to 10 Litres in volume. This is to keep the density of the foam in check. The foaming agent should not be brought in contact under any circumstance with oil, chemical or any other material that might alter its function.
The emulsion of protein foaming agent with water must be used at the earliest. It is added in proportionate amounts and the mixture is thoroughly churned. It is similar to churning of egg to develop foam. This is done so as to obtain the foam effect in concrete.
The foam imparts free flowing characteristics to this mixture. This is due to the ball bearing effect of foam bubbles, thus enabling it flow easily into all the corners of compact molds of different shapes and sizes.
This CLC brick making technology and machinery does not require any type of either vibration or compaction. Finally, the light weight bricks are cured with water for two to three weeks. Gaodetec has contributed immensely to the advancement of this technology in terms of time and money spent on it.
