Abstract

The article is devoted to the production of special cements, particularly low-shrinkage and expanding cements. Review of scientific and technical literature on this subject identified the main directions of their development. Based on the features of the raw material bases of the Republic of Armenia it has been found that more preferable and available direction of using of mentioned cements is considered to be the development based on the natural resources and waste-dust that captured from the exhaust gases of cement kilns and special expanding additives for the chemical activation of ordinary portland cement.
