Water Reducing Concrete Admixture
Advantages
Allows specified strength to be met at reduced cement content or increased workability.
- Water reduction significantly improves compressive strengths at all ages and enhances durability though the production of low permeability concrete. Minimizes the risk o segregation and bleeding and assists in the production of a dense, close textured surface, improving durability.
- Chloride free, safe for use in priestesses and reinforced concrete.
Description
Plast M 112 is a chloride free water reducing admixture based on selected sugar reduced lingo sulphonates. It is supplied as a brown solution which instantly disperses in water.
Plast-M 112 disperses the fine particles in the concrete mix, enabling the water content of the concrete to perform more effectively and improving the consistency of the concrete. The produces higher levels of workability for the same water content, allowing benefits such as water reduction and increased strengths to be taken.
Technical Support
Sigmacheme provides a technical advisory service for on site assistance and advice on admixture selection, evaluation trials and dispensing equipment. Technical data and guidance can be provided for admixtures and other products for use with fresh and hardened concrete.
Typical dosage
The optimum dosage of Plast M112 to meet specific requirements should
Always be determined by trials using the materials and conditions that well 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 0.20 to 0.50 litters / 100kg of cementations material, including PFA, GGBFS and micro silica.
Use at other dosages
Dosages outside the typical ranges quoted above may be used if necessary and suitable to meet particular mix requirements, Provided that adequate supervision is available compliance with requirement must be assessed through trial mixes. Contact sigmacheme technical services department for advice in these cases.
