Clc Blocks

Listing ID #409606

We are offering clc blocks
clc is an air-cured lightweight concrete that can be produced at project site, utilizing equipment and molds normally in use for conventional concrete.
The density recommended is 1.000 kg /m³ (oven-dried) for blocks and 1.200 kg/m³ to produce prefab elements and walls cast in-situ. The typical mix for a 1.000 kg/m³ density
clc to be used in blocks is as follows (to produce 1 m³)
cement (portland): 190 kg = 61 liters
fly-ash: 740 kg = 265 liters (approx)
water: 250 kg = 250 liters
foam (neopor-600): 423 liters
wet density 1.179 kg/m³
total volume (submerged in water) 1.000 liters (= 1 m³)
expected (oven-dry) density. Approx. 1.000 kg/m³
content of air in concrete approx. 43%
content of fly-ash in solid material (929 kg): 33%
content of fly-ash in oven-dry material: 31 %
benefits of clc blocks/element
tremendous weight reduction
high thermal insulation
optimum fire rating
substantial material savings
no gravel used.
 little cement 
less steel in structure and foundation 
easy and fast production
no primary energy and reduced transportation costs
boon for remote areas with only sand available
clc, like conventional concrete ages well, increasing its strength by as much as 50% (!) between 28 and 90 days after pouring, as long as clc draws humidity from the atmosphere it will keep on increasing its mechanical properties.
Popular block sizes are:
600x200x200/100mm
500x250x200/100mm
500x400x100mm
or as desire
blocks are cast in vertical position to offer equally accurate sides, given by the mold. Only one side (the top when cast) is not given by the mold as open-top, which is screeded. This side will face the next block in masonary anyhow.
