THE ROLES OF INTERLAYER SPACING AND WATER IN THE DRYING SHRINKAGE OF TOBERMORITE BASED MATERIALS

The roles of the interlayer spacing and water in the drying shrinkage of a hydrothermal lime-silica product have been investigated. In this work, changes in the length and weight of the specimens and the interlayer spacing of tobermorite crystals in them have been recorded at varying drying conditions. The 11.3A line of the tobermorite remained unaltered even when heated at 130 degrees (C). The major part of the drying shrinkage occured between 43% RH and drying at 105 degrees (C), though accompanied by a minor part of the water loss. The results show that the measured drying shrinkage of the material is not determined by any change in the interlayer characteristics of tobermorite. The results do not support the drying shrinkage mechanism proposed by Feldman and Sereda.
