    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 Cited by: 2. strength.

      High strength concrete (HSC) is a material often used in the construction of high rise buildings. In case of unexpected fire, building elements such as columns, slabs and walls will be subjected to extreme temperatures. In order to assess the performance of high-rise concrete members to such exposure, it is important to understand the changes in the concrete Cited by: 4. Spalling Properties of Hybrid Fibre-Reinforced High Strength Concrete at Elevated Temperatures properties during and after exposure to high temperatures is critical to the design and construction of safe and improvement of the residual mechanical properties of high strength concrete after heat exposure has been : Rodgers Bangi Mugume.
