Lightweight concrete mix design
Technical details for lightweight concrete production machinery www.concrete.ecolit.ae
PIONER GROUP is a manufacturer of dry mix for the lightweight concrete. The lightweight concrete dry mix used instead of rock wool and glass wool to achieve solid and monolithic wall structure.
Non autoclaved lightweight aerated concrete mix design:
- Portland cement 40 - 60 %
- Calcium carbonate (limestone) 40 - 60 %
- Sodium salt of naphthalene sulfonate polymerized 1%
To make your life easier we supply ECOLIT dry mix in 25 kg paper bags. It helps you to save time and get the best lightweight concrete quality in terms of density and compressive strength.
ECOLIT lightweight concrete, used for making any type of screeds and internal fillings, is a unique lightweight cellular concrete construction material, which allows for practical implementation of the new system.
When ECOLIT lightweight concrete is poured into the support structure made of cement boards, reinforced with light gauge steel profiles. It fills the space homogeneously and at the end provides for equal dry density, strength and properties throughout; naturally integrating itself at the micro level with the panels material of the same nature, resulting into a dead weight reduced, monolithic and uniform concrete construction.
ECOLIT lightweight concrete DRY MIX is a unique powder to make lightweight cellular concrete in-situ. The mortar is made from a set of components on-site, which when mixed with water becomes monolithic cellular concrete. It has a wide range of application: filling of apertures and overlapping in light gauge steel structure erection floor screeds, flat roofing, road and pipe carpeting, thermal and sound insulation elements.
ECOLIT lightweight concrete DRY MIX is supplied in 25kg paper bags should be mixed with water only in ECOLIT special mixer (foam generator).
ECOLIT lightweight concrete DRY MIX is three components pre-mix:
- Ordinary Portland Cement;
- ECOLIT modified components;
- ECOLIT FOAM generator liquid (EFG);
- ECOLIT steel protection additive.
The amount of water to be added is twenty-five to twenty-six (25 – 26) liters per fifty (50) kg of dry mix (i.e., approximately 50% by weight). Add ECOLIT lightweight concrete DRY MIX to water, turn the contents in five (5) minutes, add full to volume of the mixer premixed Ecolit Foam Generation liquid turn 60 – 90 sec. Mortar should be pumped into formwork within five (5) minutes. The formwork shall be leak-proof. ECOLIT lightweight concrete DRY MIX should be applied in accordance with ECOLIT METHOD OF INSTALLATION STATEMENT. Available in grey color. NOTICE: during operation at above 30 degrees of Celsius, an applied surface for the dry mix should ne moistened.

Dry mix bulk density is 1270 kg/m3. To produce densities from 500 kg/m3 up to 1200 kg/m3 different quantities of water and additives required.
The most applicable density for the dry wall partition system with lightweight concrete infill is 500 - 600 kg/m3
For such density Pioner lightweight concrete has such main characteristics as:
thermal conductivity 0,1359 W/(m*k)
compressive strength 2,1 - 2,8 MPA or 21 - 28 kg/cm2
fire resistance rating for 100 mm thickness is 4 hours.
acoustic insulation for 100 mm thickness is 45 db.
