Concrete Plasticizer-Capcoplast L1

Plastit L1 is a chloride free water reducing admixture based on selected sugar-reduced lignosulphonates. It is supplied as a brown solution which instantly disperses in water. Plastit L1 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. This produces higher levels of workability for the same water content, allowing benefits such as water reduction and increased strengths to be taken

Properties And Effects

Allows specified strength grades to be met at reduced cement content or increased work ability Water reduction significantly improves compressive strengths at all ages and enhances durability through the production of low permeability concrete Minimizes the risk of segregation and bleeding and assists in the production of a dense, close textured surface, improving durability Chloride free, safe for use in prestressed and reinforced concrete. Standards

Applications

To improve the effectiveness of the water content of a concrete mix. At higher dosages to provide a cost effective means of reducing concrete permeability and thereby reducing water penetration.

Scope and Method of Use

The optimum dosage of Plastit L1 to meet specific requirements should always be determined by trials using the materials and conditions that will be experienced in use. The normal dosage range is 0.3 to 0.8 kg/100 kg of cementitious material, including PFA, GGBFS and microsilica

Maintenance And Safety

Storage Plastit L1 has a minimum shelf life of 12 months provided the temperature is kept within the range of 5°C to 35°C. Should the temperature of the product fall outside this range then contact CAPCO for advice. Freezing point: Approximately -3°C Precautions Health and safety Plastit L1 does not fall into the hazard classifications of current regul ations. However, it should not be swallowed or allowed to come into contact with skin and eyes. Suitable protective gloves and goggles should be worn. Splashes on the skin should be removed with water. In case of contact with eyes rinse immediately with plenty of water and seek medical advice. If swallowed seek medical attention immediately - do not induce vomiting Fire: Plastit L1 is non-flammable
