Применение зависимости «прочность – твердость» при обследовании арматурной стали с помощью портативных твердомеров

Abstract

The aim of this work is to develop a method of determining the grade of reinforcing steel in prestressed structures using portable hardness testers. In this work we also studied the factors that influenced the measurement results, such as the size of the slice surface of the outer layer of rods, surface preparation of a reinforcing bar for measuring the static hardness, the value of the site measurements, the readings changes of a hardness measuring instrument, depending on the depth of the slice
