ABSTRACT

The properties of cement, quicklime, flyash, gypsum and other binder materials when mixed with clays are discussed. There appears to be a minimum water content or liquidity index required in order to properly hydrate soil. Observations in Boston, USA, of the effects of the heat generated by the hydration of cement and lime are reported. Possible explanations for this behavior are provided. Caution is suggested when stabilizing soil on or adjacent to slopes because of the likely short-term destabilizing effect of the increased ground temperature.
