N2 - The work is a closer analysis of Kronlöf’s earlier work [1994] and thesis [1997]. It is also related to Björn Lagerblad’s and Carsten Vogt’s work [2004] as well as Vogt’s theses [2010], all dealing with the unexplained substantial strengthening in the presence of large amounts of fine quartz. In this analysis the strengthening effect was up to 20 MPa but could be also negative. At the age of 7 days the effect depended on the average distance between particles as well as on the water to binder ratio, while at the age of 91 days it only depended on the average distance, being independent of the water to binder ratio over the wide range from 0.22 to 2.0. It was concluded that in the later case the effect was mechanical. An empirical model was made and fracture mechanical explanation given to describe the strengthening effect.
