✦ Synopsis

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 gluconate > Calcium gluconate L'action de diff~rents gluconates sur l'hydration de ciment portland a ~t~ ~tudi~e a l'aide, de la microcalorim~trie isotherme, la diffraction des rayons X et l'analyse thermique diff~rentielle. Les resultats indiquent que le gluconate agit co.me retadateur d'hydration. L'order d'action des gluconates est le suivant: Gluconate de sodium > Gluconate de potassium > Gluconate de magnesium > Gluconate de calcium 455
