Effect of modifier MB10-01 on the physical and mechanical properties of high-strength coarse-aggregate concrete

Abstract

In our study we used concrete modifier MB10-01, an admixture on an organic-mineral basis
contained of micro-silica, fly ash, hardening regulator, and superplasticizer, to produce the
high-strength coarse-aggregate concrete (HSCAC)with compressive strength of more than
100 MPa. We produced samples of HSCAC with dimensions of 100x100x100 mm and
100x100x450 mm. The physical and mechanical properties of HSCAC, such as: compressive
strength, tensile strength at bending, strength at axial tension, cracking moment and HSCAC
grade, at the curing periods of 7, 14, 28, 60 days, have been determined. The research results
have been implemented in the construction of high-rise buildings of the Moscow International
Business Center "Moscow City", and in reconstruction of the Engineering Faculty building of
the RUDN University.

Keywords: compressive strength, tensile strength at bending, strength at axial tension,
cracking moment.
