Abstract

Addition of steel fibres to concrete is known to have a significant positive influence on the mechanical properties of concrete. Micro polypropylene (PP) fibres are added to concrete to improve its performance under thermal loads such as in case of fire by preventing the phenomena of explosive spalling. An optimum mixture of steel and micro PP fibres added to concrete may be utilized to enhance both the mechanical and thermal behaviour of concrete. In this work, systematic investigations were carried out to study the influence of elevated temperature on the mechanical properties and physical properties of high strength concrete without and with fibres. Three different mixtures for high strength concrete were used, namely normal concrete without fibres, Steel fibre reinforced concrete and Hybrid fibre reinforced concrete having a blend of hooked end steel fibres and micro PP fibres. The specimens were tested in ambient conditions as well as after exposure to a pre-defined elevated te...

Key takeaways

AI generated

1. The maximum testing temperature was 800 °C, affecting concrete properties differently across mixtures.
2. Steel and micro PP fibres significantly enhance split tensile and flexural strengths by 40% to 150%.
3. Hybrid fibre concrete (HyFRC) maintains mechanical properties while preventing explosive spalling at high temperatures.
4. No negative impact on mechanical properties was observed with 1 kg/m³ of micro PP fibres included.
5. Compressive strength remains comparable across mixtures up to 800 °C, indicating thermal resilience.

FAQ's

AI generated

What are the effects of elevated temperature on concrete's compressive strength?add

The study finds that exposure to 800°C leads to a significant reduction in compressive strength across all mixtures, although micro PP fibres do not negatively influence this strength.

How do steel fibres impact concrete's tensile strength at elevated temperatures?add

Concrete with steel fibres exhibits a tensile strength increase of 40% to 150% compared to normal concrete, even at temperatures up to 700°C.

What explains the high fracture energy in fibre-reinforced concrete?add

For SFRC and HyFRC, fracture energy is at least two orders of magnitude higher than normal concrete, attributed to the activation of fibres crossing crack planes.

When do polypropylene fibres effectively prevent explosive spalling?add

Polypropylene fibres mitigate explosive spalling at temperatures between 200°C and 250°C, while melting at approximately 160°C to 170°C.

What is the influence of fibre types on the modulus of elasticity?add

The study indicates that the static modulus of elasticity remains similar among all concrete types, as fibre content is relatively low and does not significantly impact elasticity.
