Calcined Clays For Sustainable Concrete Karen Scrivener

The constituent materials for calcium hydroxide consumption and hydration experiments on blended cements were laboratory grade Calcium hydroxide (Merck, Germany), a standard OPC CEM I 42.5 R (Norcem, Brevik, Norway) and calcined marl. The raw marl (or rather calcareous clay) is a tertiary sediment that was deposited in a marine environment.

Effects of Accelerators and Retarders in Early Strength

In this study, experiments were performed on the applicability of mortars and concretes based on calcium sulfoaluminate (CSA) binders to facilitate the early strength development of ordinary Portland cement (OPC) under low-temperature conditions. An optimum mixture of CSA was evaluated to improve the early strength of OPC, and the effects of accelerators and retarders on this mixture were

Reactions and Surface Interactions of Saccharides in

Glucose, maltodextrin, and sucrose exhibit significant differences in their alkaline reaction properties and interactions in aluminate/silie cement slurries that result in diverse hydration behaviors of cements. Using 1D solution- and solid-state 13C nuclear magnetic resonance (NMR), the structures of these closely related saccharides are identified in aqueous cement slurry solutions and as
