Use of modifiers in building materials production

The technology of production of superplasticizer on the basis of technical lignosulphonates is developed. The effects of its action in different type materials are studied. On the basis of complex investigation it results the introduction of plasticizer into building in decided places. Plasticizer production is organized at the DCK-3. The effect of modifying additives on concrete mixtures and concretes is shown. The researches have been carried out for years on concretes of different building objects of Georgia. (author)
