Set-Control Additives-Plastit® NCL

Packaging
 Plastit NCL is available in 20 kg containers and 240 kg drums
 Storage
 Plastit NCL has a minimum shelf life of 12 months provided the temperature is kept within the range of 5 °C to 35 °C. Freezing point: Below -5 °C

 Particularly effective in assisting to offset the delaying effect of low temperatures on setting and strength gain
 Accelerated setting gives added protection against early age frost attack
 Also provides a degree of water reduction or increased workability
 Suitable for use in bricklaying mortar
 Chloride free, safe for use in reinforced concrete

 To accelerate the stiffening and early strength gain of Portland cement concrete and mortar
 Typical applications include concrete or mortar placed in cold weather and precast concrete

The optimum dosage of Plastit NCL to meet specific requirements should always be determined by trials using the materials and conditions that will be experienced in use. This allows the optimization of admixture dosage and mix design and provides a complete assessment of the concrete mix. A starting point for such trials is to use a dosage within the normal typical range of 1.00 to 4.00 kg/100 kg of cement

Appearance Yellow coloured liquid
Specific gravity Typically 1.14 @ 20°C
 Chloride content  Nil to BS 5075 
Air entrainment   Typically less than 2%. Additional air is entrained at normal dosages.
 Alkali content  Typically less than 1.5 g. Na2O equivalent/litre of admixture. A fact sheet on this subject is available
