Abstract
This paper presents the results of an experimental study on the effects of temperature and humidity on deformations of steel fibre reinforced concrete (SFRC). The programme consisted of creep and shrinkage tests. Creep tests were performed in the moist room (called as basic creep), drying room (drying creep and total deformation), and high temperature room (high temperature creep). Shrinkage specimens were exposed to 50% RH in the drying room. The influence of loading ages on creep and exposure ages on shrinkage of specimens was investigated. Steel fibres were used at volume fractions ranging from 0 to 2% by volume of mix. Test results indicate that the basic creep, shrinkage and total deformation measured are all lower for SFRC than for companion plain concrete. The temperature activation effect is reduced for concrete made with higher fibre content.
