Abstract: The objective of this work was to develop the relationship between the mix constituents, rheology of the cement mixture, and the mechanical properties for the production of fabric-cement composites. Various flyash contents ranging from 0, 40 %, 60 % and 80 % replacement by volume of the cement were studied in composites reinforced with AR glass fabrics. Using closed loop uniaxial tension tests, the stress strain behavior of composites was studied for various curing and accelerated ageing conditions. The rheological properties of the fresh matrix was examined and correlated with the mechanical performance. In addition, the role of the fabric reinforcement in the development of distributed cracking was documented using image analysis techniques. Results indicate an improvement in the mechanical behavior of the cement composite with flyash compared to similar composites without flyash. A good correlation was found between the rheology properties of the fresh mixture and the mechanical performance of the composite.
