Effect of different retarders on the hydration of calcium sulfoaluminate eco-cement pastes
The manufacture of Calcium SulfoAluminate (CSA) cements is more environmentally friendly than that of OPC  as their production releases up to 40% less CO2 than the latter. The main performances of CSA cements are fast ...
In-situ early age hydration of cement-based materials by synchrotron X-ray powder diffraction
Cement based binders are building materials of worldwide importance. Since these samples are very complex, the knowledge/control of their mineralogical composition are essential to design and predict materials with ...
Rheological and hydration characterization of calcium sulfoaluminate cement pastes
Calcium sulfoaluminate (CSA) cements are currently receiving a lot of attention because their manufacture produces less CO2 than ordinary Portland cement (OPC). However, it is essential to understand all parameters which ...
Tailored setting times with high compressive strengths in bassanite calcium sulfoaluminate eco-cements
This work deals with the hydration of a calcium sulfoaluminate (CSA) eco-cement prepared with bassanite and different additives (type and content) at a fixed water/CSA ratio of 0.5. Pastes prepared with bassanite show high ...
Hydration studies of calcium sulfoaluminate cements blended with fly ash
The main objective of this work is to study the hydration and properties of calciumsulfoaluminate cement pastes blended with fly ash (FA) and the corresponding mortars at different hydration ages. Laboratory X-ray ...
