The small, lightweight DXR 140 remote-controlled demolition robot is designed for indoor and outdoor demolition work.
At a third of the weight of traditional concrete, wall and floor systems made of autoclaved aerated concrete (AAC) are easy to install: an eight-man crew can install 3200 sq. ft. of wall panels or 6400 sq. ft. of flooring in just one day.
Contractors can save time and money by producing cellular concrete themselves using the CreteFoamer.

I am planning to build a house using structural concrete insulated panels (SCIP)—that is, foam panels that have wire grids on each side and are faced with shotcrete, such as 3-D panels or the Solarcrete system. Is it possible to use foamed or cellular concrete as the facing for these systems? What...

A Kansas DOT research project used three types of lightweight aggregate to develop lightweight concrete mixtures for a bridge deck and for prestressed bridge girders.
When even lower unit weight concrete is needed, or higher insulation value, cellular concrete is the solution.
Elemix concrete additive consists of innovative polymeric spheres specially formulated for use in concrete.
Geofoam SP enables the production of pervious cellular lightweight concrete from 20 to 40 lbs./cu.-ft.
AAC is beginning to catch on in the United States, where there are now three AAC manufacturing plants with several more planned. This represents a serious commitment since the cost of a plant to produce AAC blocks and panels is high.
A technical look at how AAC walls come together.

For our 50th anniversary, Concrete Construction takes a look back to our own beginnings by pulling some of our favorite products of yesteryear from our archives.
Lightweight insulating concrete “was produced with a proprietary preformed foam system which makes it possible to produce cellular concrete of the required weight and strength for each specific job.”

From our perspective, the article as well as the response by Mr. Ahal makes excellent points in addressing the issue of finishing lightweight concrete. However the real issue as we see it is not finishing lightweight concrete but finishing air-entrained concrete.

More people are choosing insulated concrete walls than wood frame walls in residential construction. Concrete homes can be constructed with insulating concrete forms (ICF), cast-in-place concrete, precast concrete panels, autoclaved aerated concrete, and concrete masonry. These construction methods...
