To achieve higher densities for foamed concrete, sand can be employed. The base mix is 1:1 to 1:3 for heavier foamed concrete, which is filler to portland cement ratio (CEM I). For more densities, say greater than 1500kg/m 3 more filler and medium sand is employed. To reduce the density, the filler amount should be reduced.
