Fine Grain Portland Cement Concrete with Complex Nanodisperse Admixture for Structure Rehabilitating

Fedorova, Galina D. / Alexandrov, Gregory N. / Yakovlev, Grigory Ivanovich / Polyanskikh, Irina S. / Pudov, Igor A.

The influence of new complex nanodisperse admixture on structure and strength characteristics of fine grain concrete used in rehabilitation of damaged concrete structures has been studied. Concrete without the admixture is more susceptible to cracking than concrete with the complex admixture, thus increasing the working time of structures. At the age of 28 days the compressive strength of fine grain concrete with the admixture reaches 52,35 MPa, the flexural strength is 5,2 MPa. The strength characteristics of concrete increased by 15%.
