Efforts to improve the environment through the conversion of waste materials into useful building products are reinforced with the advent of "lightweight cell concrete". This has created ample room for sustainable development between suppliers of building materials and high-level contractors. Although the word "concrete" is an incorrect name here, it is the most common nomenclature used to explain light aerated building blocks.
In areas with high demand for burnt bricks, CLC bricks compete favourably as alternative material. These are very useful building products that reduce deadweight of structures and accelerate the pace of construction when used as prefabricated elements for walls and pavements. Unfortunately, the basic cost of the product (as delivered at the construction site) has been too high to be offset by the economic gain that is gained due to speed and lighter structure. It is for this reason that the commonly available varieties of CLC have not proved to be very successful in India.
The actual fact is CLC / AAC blocks are very popular in market leading builders and architects. All companies that have well-learned and technically up-to-date team of planning engineers and execution engineers are using modern blocks whenever possible. Probably the common and not-so-up-to-date team of engineers, architects, and builders who stay away from using AAC / CLC blocks. The fact that all large cement companies such as Ultratech, JK, etc. and many hitech entrepreneurs have entered into the manufacture of AAC sample blocks that see a vast market in the near future.
