โฆ Synopsis
CaO rapidly reacts with Eater, even with vapor phase. To control the hydration rate of CaO, several methods have been suggested. In the present.

The rate of reaction of calcined limestone with SO, and 0, was measured at ## R. H. BORGWARDT conditions that eliminate all resistances not associated with the CaO grain surface. Reactivity increased with the square of the BET surface area when grain size was varied as an experimental parameter.
The effect of various gluconates on the hydration of portland cement has been studied employing isothermal microcalorimetry, x-ray diffraction and differential thermal analyses. The results indicate that gluconates act as retarders as follows: Sodium gluconate > Potassium gluconate > Magnesium gluco
