Abstract
Specificities of the compressive strength control of the steel fiber reinforced concrete in existing constructions
Incoming article date: 22.04.2021The article is devoted to the determination specificities of the actual compressive strength of the steel fiber concrete in existing buildings. The experimental studies results of an erecting mall constructions are presented. The monolithic fiber-reinforced concrete ground floor slabs were tested using three different destructive and non-destructive methods. The obtained results were analyzed. The high correlation (rdm-apo=0,855) of the steel-fiber reinforced concrete strength values obtained by the samples destruction and by the anchor pull out method was confirmed. The presented experimental studies results contribute to the statistical information accumulation on the issue of the actual strength of steel fiber reinforced concrete determination in full-scale constructions of erected buildings.
