X-Ray powder diffraction laboratory @ University of Málaga (UMA)
(2016-06-27)
X-Ray Powder Diffraction (XRPD) laboratory is a facility placed at Servicios Centrales de apoyo a la Investigación (SCAI) at University of Malaga (UMA) http://www.scai.uma.es/. This facility has three XRPD diffractometers ...
Synthesis and behavior of Belite-Alite-Ye’elimite (BAY) cement
(2016-06-29)
Ye’elimite based cements have been studied since 70’s years in China, due to the irrelevant characteristics from a hydraulic and environmental point of view. One of them is the reduced fuel consumption, related to the lower ...
Processing and characterisation of Calcium SulfoAluminate (CSA) eco-cements coated with a hybrid organo-inorganic material for photocatalytic applications
(2015-07-27)
On the one hand, Calcium SulfoAluminate (CSA) eco-cements are receiving increasing attention since their manufacture produces up to 40% less CO2 than ordinary Portland cement (OPC). In addition, they show interesting ...
Hydration study of alite-ye’elimite-anhydrite phases associated to BAY cement
(2017-10-18)
An alternative to decrease CO2 emissions from OPC production consists on the development of a new kind of eco-cements composed by less calcite demanding phases, such as belite and ye'elimite. That is the case of ...
Synthesis of active Belite-Alite-Ye'elimite clinker (BAY)
(2016-06-29)
Ordinary Portland cement (OPC) is an environmentally contentious material, as for every ton of OPC produced, on average, 0.97 tons of CO2 are released. Ye'elimite-rich cements are considered as eco-cements because their ...
Influence of the calcium sulfate source on the rheological behaviour of calcium sulfoaluminate cement pastes
(2013-09-13)
Calcium sulfoaluminate (CSA) cements are receiving increasing attention since their manufacture produces much less CO2 than ordinary Portland cement (OPC) [1]. In addition, they show interesting properties such as high ...
Hydration studies of calcium sulfoaluminate cements blended with fly ash
(Elsevier, 2013)
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 ...
Hydration mechanisms of two polymorphs of synthetic ye'elimite
(Elsevier, 2014-05-26)
Ye'elimite is the main phase in calcium sulfoaluminate cements and also a key phase in sulfobelite cements.
However, its hydrationmechanismis not well understood. Here we reported newdata on the hydration behavior
of ...
Reactive belite stabilization mechanisms by boron-bearing dopants
(Elselvier, 2012-01-27)
Belite-rich cements hold promise for reduced energy consumption and CO2 emissions, but their use is hindered
by the slow hydration rates of ordinary belites. This drawback may be overcome by activation of belite
by doping. ...
Proton Conductors based on Metal Phosphonate Hybrid Materials for PEM Fuel Cells
(2014-06-25)
The necessity of energy and power generation is constantly growing. Fossils fuels are quickly becoming unsatisfactory substrates due to both their emission of pollutants and their finite expectancy. Fuel cells are one of ...
