Foam concrete (FC) has the potential of being an alternative to ordinary concrete, as it reduces dead loads on the structure and foundation, contributes to energy conservation, and lowers the cost of production and labor cost during the construction and transportation. The paper reports a state-of-the-art review of foam concrete in terms of its components, manufacturing and material properties ...

Foam Concrete/Light Weight Concrete.

May 01, 2019· The slurry film reduces the friction between sand and cobble soil particles, and the shear strength of sand and cobble soil is further reduced by the foam. At the same time, bentonite has swelling and adsorption features because it is a non-metallic clay compound with montmorillonite as its main component ( Zhang and Peng, 2015 ).
