Abstract

A ‘thin-plate’ technique, which is well suited for laboratory studies on cements, has been used in equilibrium experiments aimed at studying material transport between concretes of different composition. The extent of material transport is small, but there appear to be a movement of calcium towards thin plates containing excess silica fume, where supposedly the pozzolanic reaction takes place, an aspect which can be of interest for crack-healing of cements. A model concerned with crack healing of cement is discussed. Preliminary data have been obtained in a study where thin plates have been employed to investigate the effect of leaching on the microstructure of cements using the technique of Small Angle Neutron Scattering (SANS).
