Cellular Light Weight Bricks (CLC Bricks) is a version of lightweight concrete that is produced like normal concrete under ambient conditions. It is produced by making slurry of Fly Ash, Cement, Chemicals and water, which is further mixed with the addition of preformed stable bio-degradable foam in a special concrete mixer under ambient conditions.The foam imparts free flowing characteristics to this slurry due to ball bearing effect of foam bubbles enabling it to easily flow into all corners and compact by itself in the moulds without requiring any kind of vibration or compaction.
After some time when slurry solidifies then it is cut into the required size. This is further cured with water for 14 days and then it is ready for dispatch. CLC infinitely increases its strength by hydration (forming of crystals in cement) as long as exposed to humidity in the atmosphere.
The difference between AAC and CLC lies in how the air bubbles are generated
AAC uses aluminum powder to catalyze a reaction that generates hydrogen gas - bubbles formed from the reaction and are trapped in a lime, flyash, gypsum and very small percentage of cement slurry. The slurry is allowed to set and then the product is cut into panels or blocks and placed in an autoclave to cure (an autoclave is required because the slurry has low cement contents).
CLC is a process based on making air bubbles in the form of a foam and then mixing the foam into a cement / flyash slurry. The slurry is then poured into moulds. Since CLC slurries have higher cement contents, no autoclave curing is required - instead, the finished product is cured like normal concrete or Steamed Cured with low pressure to achieve early strength.
Our manufacturing Technology is based on the CLC method.
As compared to AAC lightweight products, CLC air bubbles are significantly smaller, stronger, and each bubble is part of a closed cell system - which means Our CLC block products have lower water absorption - about half of the water absorption as AAC And Brick. Like Cement, CLC blocks increase in strength when exposed to moisture. Hence CLC bricks become tougher over time.
The advantage in using foam additives is that the foam now becomes a raw material. and as a raw material, the quality of the bubbles used can be controlled. The foam additive that our Block uses is unique - as we have designed the air bubbles so that, as compared to AAC lightweight products, they are significantly smaller, stronger, and each bubble is part of a closed cell system and that is why our block products have significantly lower water absorption. Our Block Technology is based on the CLC method, but it is a full system approach.
We have selected the best technology for all aspects of production and product quality: from QC control to placing methods and foam additive to mix designs - making our Block Technology a great and unique lightweight concrete production system.
