Determination of the Strength Characteristics of Heavy Cement Concrete Modified with SIKAPLAST-520 N
Abstract: In connection with the development and diverse use of heavy cement concretes, the tasks of improving and modifying the structure of a concrete composite began to be considered in order to achieve the necessary optimal physical, mechanical and technological characteristics. One of the main properties of heavy concrete is its strength. In this work, the effect of the plasticizing additive SIKAPLAST-520 N on the compressive strength of heavy cement concrete under normal hardening conditions was studied. The expediency of using this chemical plasticizing additive in comparison with additives of other chemical nature is determined. It has been established that the use of SIKAPLAST-520 N allows to increase the strength properties by 19 % in comparison with the control composition. It is recommended to study the chemical additive SIKAPLAST-520 N as part of an organo-mineral modifier, which presumably will further reduce the consumption of cement and at the same time increase the physical and mechanical characteristics of heavy concrete. Also, goals were set for further research in this area.
