Hydration and mixture design of calcined clay blended cements: review by the RILEM TC 282-CCL
Karen Scrivener, Franco Alberto Zunino Sommariva, Mohsen Ben Haha, François Henri Avet, Anuj Parashar, Yuvaraj Dhandapani, Sreejith Krishnan
The RILEM technical committee 282-CCL: Calcined Clays as Supplementary Cementitious Materials, investigates all the aspects related to calcined clays, from clay exploration and characterization to calcination process, hydration reactions and concrete prope ...
SPRINGER2022Radical Alkynylations with EthynylBenziodoXolones: From Photocatalysis to Direct Excitation
Jérôme Waser, Stephanie Grace Elizabeth Amos
Ethynylbenziodoxolones (EBXs) have recently emerged as potent reagents for the alkynylation of radicals. Their combination with photocatalysis allows the synthesis of valuable alkynes at room temperature. Herein, we discuss two photomediated strategies for ...
SWISS CHEMICAL SOC2022Photocatalytic Umpolung of N- and O-substituted alkenes for the synthesis of 1,2-amino alcohols and diols
Jérôme Waser, Stefano Nicolai, Stephanie Grace Elizabeth Amos
We report an organophotocatalytic 1,2-oxyalkynylation of ene-carbamates and enol ethers using Ethynyl BenziodoXolones (EBXs). 1-Alkynyl-1,2-amino alcohols and diols were obtained in up to 89% yield. Photocatalytic formation of radical cations led to Umpolu ...
ROYAL SOC CHEMISTRY2020Hydration reactions and stages of clinker composed mainly of stoichiometric ye'elimite
Karen Scrivener, Emmanuelle Boehm Courjault, Mohsen Ben Haha, Frank Bullerjahn
Ye'climitc (Ca4Al6O12SO4 or C(4)A(3)(S) over bar) is the main hydraulic mineral present in calcium sulfoaluminate cement (CSA). The hydration of ye'elimite is responsible for the early age cement properties. We identify 5 stages in the hydration of neat st ...
PERGAMON-ELSEVIER SCIENCE LTD2019Investigation of the use of Limestone Calcined Clay Cement (LC3) applied to Thailand
The replacement of clinker with supplementary cementitious materials (SCMs) is the most interesting solution to reduce the CO2 emissions from cement production. The abundant availability of clays, which have a sufficient amount of kaolinite content in Thai ...
