MARKPLAST CONLITE AE 347
DESCRIPTION
CONLITE AE347 is a liquid air-entraining admixture that provides freeze-thaw resistance, yield control, and finishability performance across the full range of concrete mix designs. Conlite AE347 is designed to generate specification-quality air systems. Based on a high grade saponified rosin formulation. Conlite AE347 does not contain intentionally added chloride. It meets the requirements of ASTM C-260 for air entraining admixtures.
FEATURES / ADVANTAGES
- Rapid air builds suitable for short mix cycles
- Used in wide spectrum of mix designs
- It help to prevent scaling by creating microscopic air voids that water trapped in the concrete can expand into when the concrete freezes, thus preventing cracks caused by the natural expansion
- Increases durability in harsh environments where concrete is exposed to deicing salts, marine salts and sulfates.
- Reduced permeability – increased water tightness
- Reduced segregation and bleeding

DIRECTIONS FOR USE
The optimum dosage of Conlite AE347 to meet specific requirements must always be determined by trials using the materials and conditions that will be experienced in use.
With air entertainers, in particular, a large number of factors affect the dosage required to obtain particular desired results. This makes it impossible to predict the dosage required for a specific mix requirement. As a guide, the dosage will generally be in the range of 0.10 to 0.25 litres/100 kg of cement to obtain air content with range between 4% to 7%. Other factors that may affect the amount of air entrained into the concrete including total cementitious content, type of pozzolanic materials, sand gradation, salt/clay in aggregates, temperature and water content. The use of fly ash, particularly high LOI fly ash, can result in a higher dosage of air entrainment.
