Cellular lightweight concrete mix design. The foamed in lwfc refers to the preformed cellular concrete foam used to generate the material. Foam concrete cellular lightweight concrete is a lightweight building material combining good mechanical strength with low thermal conductivity and ease of working. Cellular light weight concrete clc is a light weight concrete that is produced by mixing cement and flyash slurry with pre formed foam. Foam concrete also known as lightweight cellular concrete lcc low density cellular concrete ldcc discrete foamed concrete foam create cellular lightweight concrete or reduced density concrete is defined as a cement based slurry with a minimum of 20 per volume foam entrained into the plastic mortar.

Cellular concrete mix design both pervious impervious foamed concrete are available in densities starting at 20pcf wet cast which has a typical compressive strength at 28 days of 50psi up to 70pcf wet cast which has a typical compressive strength at 28 days of 1100psi. It is a low density hardened portland cement paste or mortar containing a large number of small bubbles of air which gives it a fine cellular structure. These lightweight concrete materials can be produced with densities which are 25 to 40 lower but with strengths equal to the maximum generally achieved by ordinary concrete. The maximum slump for concrete is limited to up to 100 mm.

Cellular concrete is a type of controlled low strength material clsm. It is also called as foam concrete. A very basic cellular concrete mix design would consist simply of portland cement water and externally generated foam which is also referred to sometimes as preformed foam. Lightweight concrete is made from the lightweight aggregate.

It s useful for determining batch weights required amounts of water and concrete and calculating your costs. The water cement ratio can typically vary from 40 80 and the foam content is commonly as high as 80 depending on desired density. Cjgeo does not install light expanded aggregate lightweight concrete or autoclaved aerated concrete. Clsm generally refers to flowable fill or mix designs specifically formulated for relatively low but predictable strengths.

These clc blocks are competitive with red clay bricks in pricing and offer significant savings for finished structures.
