Remember that while discussing mix-design of High strength concrete the term "cement" is use to describe all the cementious materials in the concrete and not just the Portland cement. In general, smaller size aggregates have been shown to produce higher strength concretes, for a fixed w/(c+p) ratio. However, the use of the largest possible coarse aggregate may be an important consideration in

From the general principles behind the design of high-strength concrete mixtures, it is apparent that high strengths are made possible by reducing porosity, inhomogeneity, and microcracks in the hydrated cement paste and the transition zone. The utilization of fine pozzolanic materials in high-strength concrete leads to a reduction of the size of the crystalline compounds, particularly

High-strength concrete, in the absence of pozzolanic materials, would have a substantial problem with slump loss. The use of fly ash or blast furnace slag reduces this effect and reduces the production costs of the concrete. The optimum substitution level is usually controlled by a minimum value or by the acceptable loss in 12 hour or 24 hour strength (pozzolanic materials produce lower short
