A few decades ago, before the wide spread use of superplasticizers and other additives, several correlations of practical use was established between mix design parameters and properties of the hardened concrete. The w/c-ratio was up till then a relevant and important parameter when designing a concrete structure for a specific service life. Superplasticizers, fillers, new binders etc. have changed the relevance of correlations between the mix design and the properties of the hardened concrete.
At the very best, the w/c-ratio can only give an approximation of the hardened concrete properties on modern concrete design given a number of circumstances. A measured value on the hardened concrete is clearly better and the results presented here show that a number of properties would be possible to predict based on just one or two measured properties. Is it for example possible to predict the chloride diffusion coefficient based on the knowledge of the compressive strength? The results presented in this paper are the first step in a project which serves to illustrate the possibilities with performance based requirements for concrete durability.
