Cellular concrete is also used for the production of blocks for walls (filling in and partitioning).
The main densities at which blocks in cellular concrete are made are:
FORMULATION OF BLOCKS IN CELLULAR CONCRETE AT DIFFERENT DENSITIES
|500 kg/m3||250 kg||150 kg||95 kg||1 litres|
|570 kg/m3||310 kg||150 kg||100 kg||0,95 litres|
|600 kg/m3||310 kg||210 kg||110 kg||0,93 litres|
|700 kg/m3||340 kg||290 kg||110 kg||0,90 litres|
|800 kg/m3||350 kg||370 kg||120 kg||0,80 litres|
|900 kg/m3||350 kg||470 kg||140 kg||0,75 litres|
Note: all this data is merely indicative and should be confirmed with practical tests on materials actually in use.
The technology for producing non-autoclaved blocks in cellular concrete is the most complete and ecological because no autoclave is used, because the modest use of energy and of raw materials.
Given the economy and the reduced dimensions of the plant, it is possible to relocate the production of non-autoclaved blocks in cellular concrete to any user market (even modestly sized yards), reducing the cost of transport to the minimum which on the other hand is significant in the case of using traditional materials.
The versatility of this technology is also in the dimensions of the blocks: The formwork developed by Isoltech allows for the production of non- autoclaved blocks in cellular concrete of various sizes, for use in partition and external walls. The blocks can be for filling in/partitioning and seismic, and are made thanks to the IBS-08 machine, in manual or automatic versions, with or without pump.
All blocks have to be laid with a thin filmed bonding agent obtained with ACRI 105 mixed with concrete, sand and water in appropriate proportions.
The walls will have to be finished with plaster applied in a specific sequence prescribed by ISOLTECH. The plaster is obtained by mixing concrete, sand, water and ACRI 105 and is applied in two layers with ACRIVER coating mesh.
All walls, internal and external, partitions and infill blocks must be finished with the treatment described above.
CELLULAR CONCRETE MASONRY BLOCKS
Blocks in cellular concrete obtained with the Isoltech production system may be made according to choice, in the following dimensions:
DIMENSIONS OF FORMWORK (300X60X25 CM)
|DIMENSIONS OF FORMWORK||PRODUCTION||BLOCK DIMENSIONS|
|300x60x25 cm||Blocchi Interlock||60x25x7,5 cm|
|300x60x25 cm||Blocchi Interlock||60x25x8 cm|
|300x60x25 cm||Blocchi Interlock||60x25x10 cm|
|300x60x25 cm||Blocchi Interlock||60x25x15 cm|
|300x60x25 cm||Blocchi Interlock||60x25x20 cm|
|300x60x25 cm||Blocchi Interlock||60x25x30 cm|
|300x60x25 cm||Blocchi Interlock||60x25x35 cm|
Note: To improve the handling of the particularly voluminous blocks, recesses have been introduced which act as handles.
