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 ...
Characterization of C-S-H gels by pair distribution function analysis
(2021)
Portland cement (PC) is the most manufactured world product. However, cement industry is one of the major contributors for greenhouse gas emissions. On average, for every ton of grey PC clinker, around 0.87 CO2 tons are ...
Time-dependent monitoring of cement hydration by combined laboratory x-ray microtomography and powder diffraction
(2022-06-30)
Following the reaction degree of amorphous phases in cements is very challenging. It becomes even harder when some additions (supplementary cementitious materials) are employed. Nowadays, calcined clays are attracting a ...

Effect of different retarders on the hydration of calcium sulfoaluminate eco-cement pastes
(2014-07-09)
The manufacture of Calcium SulfoAluminate (CSA) cements is more environmentally friendly than that of OPC [1] as their production releases up to 40% less CO2 than the latter. The main performances of CSA cements are fast ...
Advanced synchrotron studies of ye'elimite-based cement pastes
(2018-07-18)
Synchrotron characterization techniques [1] are being used to study Portland-based cements and recently also CSA and related cements. A key property of these techniques is that they do not require sample preparation, so ...
In-situ hydration study of sulfobelite eco-cements

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 ...
In-situ Molibdenum X-ray powder diffraction study of the early hydration of cementitious systems on a humidity chamber
(2016-07-06)
The durability of cement-based construction materials depends on the environmental conditions during their service
life. A further factor is the microstructure of the cement bulk, established by formation of cement hydrates. ...
