Abstract
Polymer-modified mortars (PMMs) using recently developed redispersible polymer powders and aqueous polymer dispersions have become popular construction materials in the world, particularly for finishing and repairing works, because of their excellent performance and durability. In order to develop usable models of structure-property relationships for such systems, the authors have focussed their studies on the microscopic level because such aspects still need more information. In this context, they have already reported their detailed observations on the formation of Ca(OH) 2, AFt, AFm, hollow tubules, and hollow crystals in PMMs (1–5). However, studies on hydrogarnet-type cubic crystals in PMMs were not available by that time. The purpose of this paper is to establish morphologically the formation of hydrogarnet-type cubic crystals in PMMs.
