Conduction calorimetry has been used to study the patterns of early heat evolution during the hydration of Portland cement. In particular, the effect of sulphate on the rate of heat liberation has been investigated with reference to the differences observed depending on whether the sulphate is prese
Data from small-angle X-ray scattering experiments are used to determine the fractal types and dimensions of hydrated portland cement pastes over a range of length scales. The larger-scale, 200-1500 A, geometry at most degrees of water saturation is found to be that of a rough surface fractal. The s
Alkalies present in cement in the form of Na?SO 4 and/or K2SO 4 do not alter the progress of C3S and C3A hydration. The setting time becomes accelerated especially with K2SO 4 due to the formation of syngenite CaSO4.KpSO4"HpO. The compressive strength
