Cemairin F302
Air entraining agent for concrete
Cemairin F302 is a liquid foaming agent used to produce light weight foam concrete. Cemairin F302 should be used with appropriate foam generator to produce consistent pre-foam which when mixed with cement only or with sand/cement mortar will produce light weight mixes with densities between 300 – 1500 kg/m³.
- Gives excellent thermal insulation with good compressive strength.
- Excellent foam stability.
- Can be used with all types of cement.
Light weight concrete produced with the aid of Cemairin F302 is typically used in the following applications:
- Roof thermal insulation.
- Under-floor heat insulation.
- Light weight block.
- Void filling.
- Trench reinstatement.
Cemairin F302 is available in 20 litre cans/pails, 210 litre drums and 1000 litre bulks supply.
Cemairin F302 has a shelf life of 12 months from date of manufacture if stored at temperatures between 2°C and 50°C.
The guidance dosage of Cemairin F302 is 0.5 - 6.0 litre per 100 kg of cementitious materials depending on purpose and method of use. The exact dosage depends upon the required final dry density.
The optimum dosage of Cemairin F302 to achieve the desired dry density should always be determined by site trials.
