Abstract
The effect of various additionals on the direction of fine-grained concrete regulation is observed. The effect of the polycarboxylate superplasticizer mechanism was introduced according to the characteristics of the additional’s composition. The effect of a mineral additional on the physico-mechanical properties of finegrained heavy concrete upon the lime is studied. In the result the usage of complex materials fine-grained concrete with the structure of 8 MPa curved and 80,89 MPa pressure boundary of B 60 class were worked out. The prime cost of the developed fine-grained concrete is within 39792 ... 44907 drams.
