Abstract
A model which correlates the strength of portland cement paste with the chemical composition of the cement is proposed. The model is based on well-established strength-porosity functions, where the porosity is calculated from data on: 1. 1) the amount, 2. 2) the degree of hydration, and 3. 3) the specific solid-volume increase of hydration for each of the hydrating phases in the cement. The ability of the model to fit actual strength measurements supports the view that all phases in the cement contribute to strength in accordance with their capacity for porosity reduction. The influence of SO 3 is also described by the model. Problems regarding the specific volume of the C-S-H gel are discussed.
