The use of organic additives for the cement consumption
Incoming article date: 01.12.2017High cost and shortage of cement in the construction market of the Russian Federation determines the need to find ways to save it. One of the promising directions of improving the technology of concrete, providing the opportunity for significant savings of cement is the production of concretes of new generation. Such concretes are of high quality or highly functional. Mandatory element of the technology of such concretes is the introduction in their composition of organic additives (OMD). Using the methods of the experiment planning theory in the developed compositions of organic additives depending on the fineness of the mineral component and dosage of superplasticizer. It is established that the use of the proposed organic-mineral additives will allow to save from 15 to 30% of cement without loss of concrete strength.
