ECO-B bricks are produced by adding millions of Micro-Sized air bubbles into a cement based mixture. The addition of millions of air bubbles is achieved by using a Proprietary Foam Generator to produce highly stable foam and injecting the Foam directly into a concrete mix containing a cement (OPC 53grade) / fly ash/ water slurry. The amount of cement, water, fly-Ash and foam included in the Light weight Cellular concrete mix design depends on the required properties (i.e. strength, thermal conductivity or durability). Also, depending on the required CLC density and variance, an appropriate mix is selected.
