Development Of Test Methods For Fibre Reinforced Roofing Tiles

A series of sisal fibre reinforced concrete roofing tiles were produced and tested using both standard methods and non-standard methods of testing corrugated Roman II tiles. The concrete was blended with ground granulated blast-furnace slag to various degrees to determine the optimum blend. The effectiveness of solar chamber curing was studied. The curing method was based on the utilization of solar energy to produce moisture movement in a sealed system with a chamber temperature that is significantly higher than the normal level in the surroundings. The failure modes and strengths of the tiles under bending load were presented and discussed. The effect of admixtures was also investigated on some of the samples. The viability of the techniques studied for commercial production of concrete roofing tiles was discussed.
