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

The early stages of cement hydration were investlgated by proton spinspin relaxation time (T c) measurements because these experiments can be performed much faster (in several seconds) than the characterlstlc time for a change in hydration evolution.

Na20 and K20 in absence of S03 are incorporated preferentially into the C3A phase of portland clinker altering its modification from cubic to orthorhombic. The hydration of Na20 doped C3A is retarded and that of K20 doped C3A accelerated in the resultant cements. The progress of C3S hydration and st
