✦ Synopsis

A model for the expansion of a silica glass/alkaline OPC mortar has been developed which is based on the observation that the main reaction product of the glass is a layer of CSH gel formed at its surface.

In the model, which takes into account the mechanical -properties of the system, the increase in voltm~e of the glass plus its reaction product layer above that of the original glass leads to a predicted mortar expansion which is slightly less than that observed, but of the correct order of magnitude.

Dr. Chatterji queries why coarse clinker grains added to an OPC paste did not produce significant expansion by virtue of the larger volume of hydration product compared to the volume of clinker from which it formed. It may be suggested that the answer lies in the location of the hydration product of
