plastit L1- ligno bese water reducer

Water Reducing Admixture

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. Plastit L1 is suitable for concrete with water-cement ratio is higher than 45%.
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. 
Plastit L1 conforms with BS 5075 Part 1 and with ASTM C494 as Type A.
