About UsLight weight concrete - or foamed concrete - is a versatile material which consists primarily of a cement based mortar mixed with at least 20percent of volume air. The material is now being used in an ever increasing number of applications, ranging from one-step house casting to low density void fills.
Foamed concrete has a surprisingly long history and was first patented in 1923, mainly for use as an insulation material. Although there is evidence that the Romans used air entertainers to decrease density, this was not really a true foamed concrete. Significant improvements over the past 20 years in production equipment and better quality surfactants foaming agents has enabled the use of foamed concrete on a larger scale.
Lightweight and free flowing, it is a material suitable for a wide range of purposes such as, but not limited to, panels and block production, floor and roof screeds, wall casting, complete house casting, sound barrier walls, floating homes, void infill, slope protection, outdoor furniture and many more applications.
Not everyone knows that density and compressive strength can be controlled. In LCM this is done by introducing air through the LCM proprietary foam process which enables one to control density and strength precisely.
Normal concrete has a density of 2,400 kg/m3 while LCM’ s densities range from 1,800, 1,700, 1,600 down to 300 kg/m3. Compressive strengths range from up to 40 mpa down to almost zero for the really low densities. Generally it has more than excellent thermal and sound insulating properties, a good fire rating, is non combustible and features cost savings through construction speed and ease of handling.
LCM is a Malaysian technology, the result of over 20 years of RandD, fine tuning the product and researching the possible applications. It is used in over 40 countries world wide today and has not reached the end of its possible uses. |
