Summary
A brief account is first given of the difficulties encountered when trying to make a proper choice of fracture-facilitating surface-active agents for cementstone. In this context we describe the “Re-binder-effect”, the notion of zêta potential, and the present knowledge about the adsorbtion behaviour of calcium alumino silicates in alkaline aqueous environments. Comparison of the results of zêta potential measurements by means of electroosmosis, and measurements of the fracture toughness Klc, both performed on cementstone in aqueous electrolytic solutions of varying concentration which were kept saturated vs. calciumhydroxide, shows a distinct maximum for Klc at the so-called “Iso Electric Point”. A preliminary model is suggested to explain the observed behaviour of Klc as a function of the concentration of the electrolytic solution.
