LIGHTWEIGHT AGGREGAT
Lightweight aggregate concrete can be produced using a variety of lightweight aggregates. Lightweight aggregates originate from either
Natural materials like volcanic pumice/batu apung, tuff, dll.
The thermal treatment of natural raw materials like clay, slate or shale i.e. Leca
Manufacture from industrial by-products such as fly ash, i.e. Lytag
Processing of industrial by-products like FBA or slag
trench reinstatement
is an ideal material for trench reinstatement (the filling of trenches dug in roads when pipes are laid or repairs are carried out). The traditional methods of filling trenches in the roads, i.e. the use of granular fill materials, result in settlement and damage to the road and potentially, to the pipes. With foamed concrete there is no settlement; and because the foamed concrete is very fluid, it will fill any voids and cavities in the trench sides
Bridge Abutment
is particularly suitable for bridge abutments because it does not impose the large lateral loads, which can be a problem when using traditional granular materials. With traditional abutments, there is a lot of sideways pressure against the bridge walls caused by the materials used and their compaction.
Void Filling
is also very useful for void filling. As it is very fluid it will pour into even the most inaccessible places. It can be used for planned work, but also in emergencies to provide stability and support very quickly.
Roofing Insulation
has been supplied for roofing insulating. A low density mix is chosen and the resulting air content gives the material excellent thermal insulation properties. The low density also has the advantage that it does not significantly add to the overall weight of the roof.
