Early hydration reactions of portland cement-silica fume blends were followed by conduction calorimetry, Ca(OH) 2 estimation, and later reactions by Ca(OH) 2 and non-evaporable water contents. Silica fume accelerated both CsS and CsA hydration in the first few hours. At longer periods pastes of bl

โฆ Synopsis
Hydration of portland cement blended with granulated blast furnace slag and rice husk ash in presence of bag house dust has been studied by measuring non-evaporable water contents, heat of hydration and compressive strengths. Analysis of liquid phase for Ca" ion estimations has been made. Hydration characteristics have been discussed.

This paper focusses on the evolution of the heat of hydration of hardening concrete or cement based materials. Based on isothermal and adiabatic hydration tests a new general hydration model is developed, valid both for portland cement and blast furnace slag cement. This hydration model enables the
