Evaluation of micro-concrete fibre reinforced roofing tiles with SCM
Non-asbestos fiber-cement roofing tiles reinforced with cellulose pulp from sisal (Agave sisalana) were produced using vibrating table techniques. The product evaluation was carried out from two points of view: to determine to role of the sisal fible in the final product and to determine how to improve the carbon footprint of the tiles without compromising production or performance through the partial replacement of cement with supplementary cementitious materials (SCM). A series of concrete roofing tiles produced using cements with various levels of blending with ground granulated blast-furnace slag (GGBS) and tested using standard methods of testing corrugated tiles. Different curing method was employed in the production based also on the carbon footprint of the curing methods. The effectiveness of each of the method of curing was investigated. The failure modes and strengths are presented and discussed.
