EXPERIMENTAL STUDY ON THE PERFORMANCE OF HYBRID FIBRE REINFORCED CONCRETE AT ELEVATED TEMPERATURES
Journal Title: International Journal of Innovative Research in Advanced Engineering - Year 2016, Vol 0, Issue 0
Abstract
The main objective of this study is to understand the fundamental behaviour of FRC when it is exposed to elevated temperatures. However, rather than relying on one type of fibre, this study proposed of mixing two different types of fibre in concrete which will then be exposed to elevated temperatures from normal temperature i.e. 27 °C (room temperature) to 200°C, 400 °C and 600 °C for one hour and cooled to room temperature before testing. The two types of fibres used, steel and Recron 3s (polyester) fibres, have different characteristics. The study is mainly focused on the experimental work. Concrete mixes prepared are without fibre, with either or both steel fibre and Recron 3s fibres. Dosage of steel fibre is 1% by volume of concrete and Recron 0.1% by volume of concrete. The study deals with the comparison of residual strength of hybrid fibre reinforced concrete with fibre reinforced concrete. Experimental work was carried out to study the impact of elevated temperatures on the compressive strength, tensile strength and ultrasonic pulse velocity.
