EFFECT OF MODIFIER MB10-50C ON THE PHYSICAL AND MECHANICAL PROPERTIES OF HIGH-STRENGTH FINE-AGGREGATE "POWDERY" CONCRETE

In this study we used concrete modifier MB10-50C, an admixture on an organic-mineral basis contained of micro-silica, fly ash, hardening regulator, superplasticizer, to produce the high-strength fine-aggregate "powdery" concrete (HSFPC). We produced samples of HSFPC with dimensions of 100x100x100 mm and 100x100x400 mm. The physical and mechanical characteristics of HSFPC, such as: compressive strength, tensile strength at bending, strength at axial tension, cracking moment, HSFPC grade, and elastic modulus, 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.
