CONCRETE TREATING METHOD Russian patent published in 1998 - IPC

FIELD: construction engineering. SUBSTANCE: this relates to concrete treating methods aimed at improving operating properties of concrete and particularly at weakening negative results of reactions of alkali-filler or alkali-silica. According to method, introduced into concrete mass is substance which retards reaction of alkali-filler or alkali-silica in concrete mix. Method implies initiation of migration of aforesaid substance in concrete mass. Migration of this substance is induced by applying electric field to concrete mass. Application of aforesaid method ensures retardation and complete elimination of aforesaid harmful reactions. EFFECT: higher efficiency. 16 cl
