ABSTRACT ABSTRACT
The behavior of concrete structures under thermal stresses is of significant importance to energy consumption of buildings. This study aims to investigate the thermal properties of concrete made from 0.64 water/cement ratio, 0%, 0.5%, 1.5% and 3% by weight of cement replacement with Sisal fibre (SF) and then subjected to elevated
temperatures so as to establish a correlation between thermal conductivity and thermal diffusivity with thermal comfort of Sisal fibre (SF) made concrete. The results show that at 900°C, SF-1.5 and SF-3.0 had the lowest thermal diffusivity value of 0.24mm/s among all series. It is concluded that the incorporation of Sisal Fibre improves the thermo-physical properties of concrete at high temperature. Sisal fibre can be used to delay heat transmission in concrete elements in case of fire, since it has
the ability to increase specific heat as well as reducing thermal conductivity and thermal diffusivity in concrete
