Foaming agents are chemical additives that produce a foam in the concrete mix which creates a light weight cellular structure. Foam concrete is typically used in geotechnical applications due to its low density and good shear resistance, limiting the risk of damage to soils and other sub-grade materials [2].
The type of foaming agent is important as it determines the characteristics of the foamed product such as stability, water absorption and frost resistance. Several foaming agents are available, including a range of straight synthetic (SS) and protein-based products. It is recommended that any chosen foaming agent be laboratory tested with local materials to confirm expected compatibility.
The pore size distribution and porosity of the foam are also important in foam concrete. Q. h. o, v.
Using different types of aggregates is also important in foam concrete. l. o. j. Pasupathy et al. n, t.
a, as well as the thermal conductivity. Ntxiv rau, it is reported that granulated blast furnace slag is useful for reducing the hydration heat and temperature development in foam concrete.
