  • CEMENTITIOUS COMPOSITES
    Publication number: 20090306249
    Abstract: A method of improving the stress strain characteristics, the ductility, the energy absorbing characteristics, the fractal roughness and the material roughness of a cementitious mix includes adding at least 1%, by weight of the total weight of the cementitious mix of poly(vinyl butyrate) in addition to a reinforcing agent, preferably poly(vinyl alcohol). In a preferred embodiment, the amount of poly(vinyl butyrate) is about 40% to about 50%, by weight. This provides the optimum levels of performance of the characteristics listed above.
