RELAMIKS-M, COMPLEX ADDITIVE TO CONCRETES AND MORTARS

摘要

The invention relates to the composition of complex additive to concrete mixture and can be used in production of concrete and reinforced concrete products and structures. Antifreezing complex additive for concretes and mortars comprises superplasticizer, technical lignosulphonates – LST, potash and additionally contains sodium formate in such component ratio mass % (to dry substance): superplasticizer 41-60; LST 0.3-0.4, potash 5-40, sodium formate 30-40. It is provided the decrease of shrinkage deformation at retaining of plastifying ability. As superplasticizer S-Z or Poliplast SP-1 can be used.
