Advances in understanding cement hydration mechanisms
Karen Scrivener, Patrick Juilland, Aslam Kunhi Mohamed, Alexandre Reda Constantin William Caleb Ouzia
Progress in understanding hydration mechanisms of alite and Portland cement is reviewed. Up to the end of the induction period, dissolution rates determined by the undersaturation of the solution dominate the reaction, but, better understanding is needed a ...
PERGAMON-ELSEVIER SCIENCE LTD2019Investigation of C-A-S-H composition, morphology and density in Limestone Calcined Clay Cement (LC3)
Karen Scrivener, Emmanuelle Boehm Courjault, François Henri Avet
In this study, the C-A-S-H composition, morphology and density are characterized for Limestone Calcined Clay Cement (LC3-50) blends containing clays with various kaolinite contents. Significant incorporation of aluminium is observed for LC3-50 blends compa ...
PERGAMON-ELSEVIER SCIENCE LTD2019Impact of Embodied Energy on materials/buildings with partial replacement of ordinary Portland Cement (OPC) by natural Pozzolanic Volcanic Ash
This work studies the effect on Embodied Energy (EE) of concrete when Ordinary Portland Cement (OPC) is partially substituted with natural Pozzolanic Volcanic Ash (VA) at the material and the building scale. The work aims to demonstrate potential improveme ...
2018Influence Grinding Procedure, Limestone Content and PSD of Components on Properties of Clinker-Calcined Clay-Limestone Cements Produced by Intergrinding
Karen Scrivener, Albert Perez, Aurélie Rosine Favier
This paper looks at the study of intergrinding for the production of ternary cement based on clinker, calcined clay, limestone and gypsum with 50% of clinker substitution (LC3). The impact of grinding time on clinker, limestone and calcined clay PSD, and h ...
Springer2018Influence of calcium and magnesium carbonates on hydration kinetics, hydrate assemblage and microstructural development of metakaolin containing composite cements
Mohsen Ben Haha, Pawel Tadeusz Durdzinski
The hydration of metakaolin composite cements containing quartz, natural limestone and dolomite rock is studied using a multi-method approach and modelling. The study demonstrates that the calcite present in limestone and dolomite rock is very reactive. Co ...
PERGAMON-ELSEVIER SCIENCE LTD2018The Effect of Alkali on the Properties of Limestone Calcined Clay Cement (LC3)
Karen Scrivener, Wilasinee Hanpongpun
The impact of alkali content on the properties of Limestone Calcined Clay Cement (LC3) was investigated in this study. KOH was added in order to increase the alkali content of the blended cements from 0.44% Na2Oeq to 1.21% Na2Oeq. The increase of alkali ac ...
Springer2018First-principles investigation of phase stability in the Mg-Sc binary alloy
The recent discovery of shape memory behavior in Mg-Sc alloys has opened the door to the possibility of lightweight shape memory alloys. Very little is known, however, about martensitic phase transformations or about equilibrium phase stability in this all ...
APS2017Investigation of the grade of calcined clays used as clinker substitute in Limestone Calcined Clay Cement (LC3)
The combination of calcined kaolinitic clays and limestone in Limestone Calcined Clay Cement (LC3) is a promising approach to reduce the cost and the CO2 emissions of cement production by reducing the clinker content of cement. This thesis investigates the ...
EPFL2017Synthetic Calcium Silicate Hydrates
Since the introduction of cementitious materials over 200 years ago, its use has multiplied many fold to be currently at 3 billion tonnes per year, accounting for about 8% of worldwide carbon emission which is forecast to double within the next 30 years. U ...
EPFL2017Low-temperature curing strength enhancement in cement-based materials containing limestone powder
Franco Alberto Zunino Sommariva
With the ongoing sustainability movement, the incorporation of limestone powder in cementitious binders for concrete in the U.S. has become a subject of renewed interest. In addition to accelerating the early age hydration reactions of cementitious systems ...
