Cement pastes made with different water-cement ratios were hydrated at different temperatures for different times. The main factor influencing the strength properties of the obtained samples was found to be their porosity, however pores with radii of less than 10 nm affected the resultant strength o
In as series of cements made out of clinkers with variable C3A/C4AF ratios and containing different amounts of gypsum, the strength development and the composition of the hydrated material were studied. For a single clinker composition the obtained strength appears to be just a function of porosity.
