Hyperplasticiser for concrete with high mechanical strength and low loss of workability. Mapefluid X408 is used to make high performance concrete with high fluidity (class S4 and S5 according to UNI 9858 and ENV 206). Mapefluid X408 is suitable for all applications where a low loss of workability and a rapid development of early mechanical strength is required. Mapefluid X408 is a formaldehyde-free liquid additive with a base of non-sulphonated acrylic polymers, which disperses cement granules. To use, add Mapefluid X408 directly to the mix, after adding the other ingredients (cement, aggregate, water). Mapefluid X408 can also be diluted into batching water beforehand, since its hyper-plasticising action is not affected by the mixing method. Coverage 0.9-2.4 kg for every 100 kg of cement (0.8-2 l). Packaging 200 l drums, 1000 l tanks. Also available in bulk on request.
