Extreme vertices design of concrete with combined mineral admixtures
Extreme vertices design method was used to reduce the complexity of the mix proportioning of concrete with combined mineral admixtures. It chooses all vertices, or additionally the centroid, of the whole experimental field, and centroids of the boundary surfaces as experimental points. With only nine experimental points designed by the method, the relationship between concrete strength and binder composition of Portland cement-zeolite-fly ash three-component binder system was established through least square regression with error of the regression estimation less than 6%. It yielded a good prediction on 7-day and 28-day compressive strengths of this concrete.
