CELLULAR CONCRETE PREFABRICATED PANELS

Cellular concrete is also applied in the making of pre-fabricated panels.
Their production is obtained from a single composition of mix. There may be other processes such as washed gravel, white overlay concrete, etc., according to aesthetic requirements. The pouring surfaces are nevertheless fully similar to those of a normal concrete.

The production of compacted panels may be achieved with horizontal formwork, such as with battery moulds.
The particular composition of the concrete indicated above resists vertical collapse even in formwork of 3 metres in height.
Nevertheless, of particular importance in this case is curing of the product.

THERMALLY GRADED SANDWICH PANELS

A new technology is available with thermally graded “sandwich” panels. Within the two rigid surfaces, cellular concrete is used as an insulation core at a density of 130 kg/m3, as against polystyrene.

The most usable density for making pre-fabricated panels, such as for vertical structures cast on site, are:

DENSITY	CONCRETE	SAND	WATER	FOAM
1000 kg/m3	350 kg	590 kg	140 volume in litres	490 litres
1200 kg/m3	400 kg	750 kg	160 volume in litres	380 litres
1400 kg/m3	400 kg	900 kg	168 volume in litres	310 litres
1600 kg/m3	400 kg	1100 kg	170 volume in litres	240 litres
