Kadol L. Sulphate reslstant concerte on standard portlandcements with organo-mineral composition.

Sulphate resistant conerete on standard portlandcements with organo-mineral composition. The work with the problem of producing durable and econo- mically effective sulphate-resistant concerte based on the standard portlandcements. This material has been produced by means of adding organic and mineral complex (OMC) of .polyfunctional action into the concrete mix. The complex produced by shlam bubbling together with sulphate suspen- sion and organic plasticizer (PFM-BC) is characterized by special effect on the concrete itself and accompanied by the rise in its sulphate-resistance by 1.5 - 2 times reaching the Kc=0.8 -1.1. The technology of producing OMC along with the method of definition and optimization of the concrete's componental structure under given firmness and necessary sulphate- resistance have been worked out as well.
