BOND BEHAVIOUR OF REINFORCED CONCRETE AT LOW TEMPERATURE

This paper focuses on the experimental results of the thermal behaviour of concrete and bond between reinforcement and concrete at very low temperatures down to -165C. The aim of the experimental investigation is to determine the bond stress-slip relationships with the aid of a pull-out test as a function of the temperature and moisture content of the concrete. Typical features associated with low temperatures will be discussed, particularly at -40 and -80C. It is found that for sealed and air-dry concrete crack width and crack spacing can be predicted at low temperatures with the aid of classical formulae.
