Foam concrete is a new form of construction material that combines sand, aggregates and cement with foam making agent to produce lightweight, self-compacting and durable concrete. It is poured into a mould or a form and can be cut to different sizes for use in structural elements such as beams, slabs and walls. Foam concrete can be used in place of traditional forms or mortar and is much lighter than conventional concrete because of its thixotropic properties (ability to flow like a milkshake) that are derived from the interaction between the foam bubbles and the sand and aggregates in the mixture.
The workability of foam concrete depends on the water-cement ratio and type of aggregates. The higher the water-cement ratio, the more fluid the concrete is and the easier it is to pour. However, T, h. a [5,15]. u. m, geocement and alkaline Portland cement. d, e. Ntxiv rau, j.
