Textural and compositional features of reaction products in the system kaolin–lime–water were examined by electron microscopy and electron diffraction. Electron micrographs of replicas of fracture surfaces of compacted mixtures and transmission electron micrographs of powdered compacts showed considerable attack of kaolinite particles by hydrated lime and indicated formation of significant amounts of calcium silicate hydrate phases. Electron diffraction of reaction products confirmed the presence of calcium silicate hydrates. The presence of these hydrates is undoubtedly responsible for the stabilizing effects of lime which have previously been reported in the literature.
