✦ Synopsis

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 blends hydrated to a greater extent than mortars, possibly because sand acted as a Ca(OH) 2 sink in the mortars.

The objective of this study was to determine the changes in the hydration process of cement paste as increasing amounts of silica fume are incorporated at high and low w/(c+sf) ratios. The hydration process of cement/silica fume paste was followed from the estimation of heat of hydration, Ca(OH)2 co

In an examination of a 1-year oM hydrated silica fume bearing cement paste a number of large (35-80 Ima) rounded siliceous particles were found that had apparently been derived from the coarse fraction of the silica fume. Calcium had diffused inward from the periphery of the grains, and in most case

Properties such as porosity, pore-slze distribution, surface area and drying shrinkage are determined for silica fume-portland cement blends (0-30% silica fume) cured from I to 180 days at w/(c+sf) of 0.25 and 0.45. Porosity was measured by helium, mercury and water techniques. It is shown that in p
