Micro-scale Cracking of Concrete due to the Alkali-Silica Reaction

Jean-François Molinari, Barbara Lothenbach, Emil Gallyamov

Alkali-silica reaction (ASR) is a concrete disease that leads to its degradation. ASR is the reaction between the amorphous silica (SiO2 ) and the alkali ions (Na + , K + ), leading to expansion of concrete in presence of Ca 2+ . In this study, it is assum ...

Tensile response of UHPFRC under very low strain rates and low temperatures

Emmanuel Denarié, Mohamed Abdul Hafiz

This paper addresses the uniaxial tensile response of Strain Hardening Ultra High-Performance Fiber Reinforced Concretes (SH-UHPFRC) subjected to very low strain rates and low temperatures. The influence of four different strain rates; 1 × 10−5, 1 × 10−7, ...

Concrete Performance of Limestone Calcined Clay Cement (LC3) Compared with Conventional Cements

Karen Scrivener, Lionel Sofia, François Henri Avet

This study aims to demonstrate the robustness of concrete made of limestone calcined clay cement (LC3). Two campaigns were carried out using 375 kg.m(-3) and 500 kg.m(-3) of binder and targeting plastic and self-placing workability, respectively. The concr ...

Effect of replacement of silica fume with calcined clay on the hydration and microstructural development of eco-UHPFRC

Karen Scrivener, Wei Sun, Wei Huang

In this paper, the replacement of high cost silica fume with calcined clay was investigated in UHPFRC mixes. The impact of two grades of calcined clay on the hydration and microstructural development of UHPFRC matrices was investigated, where 54% of the ce ...

Application of micro X-ray diffraction to investigate the reaction products formed by the alkali–silica reaction in concrete structures

Gervais Chapuis, Alla Arakcheeva, Philip Pattison

Alkali-silica reaction (ASR) is one of the most important deterioration mechanisms in concrete leading to substantial damages of structures worldwide. Synchrotron-based micro-X-ray diffraction (micro-XRD) was employed to characterize the mineral phases for ...

Carboxylic Acid Functionalized Clathrochelate Complexes: Large, Robust, and Easy-to-Access Metalloligands

Rosario Scopelliti, Kay Severin, Kurt Schenk, Philip Pattison, Euro Solari, Mathieu Jérémie Marmier, Matthew David Wise

Polycarboxylate ligands are among the most important building blocks for the synthesis of metal–organic frameworks (MOFs). The ability to access these ligands in an efficient way is of key importance for future applications of MOFs. Here, we demonstrate th ...

The pore solution of blended cements: a review

Barbara Lothenbach, Ruben Anton Snellings

This paper is the work of working group 3 of the RILEM Technical Committee on Hydration and Microstructure of Concrete with SCM (TC 238-SCM). The pore solution is an essential but often overlooked part of hydrated cements. The composition of the cement por ...

Ketenimines from Isocyanides and Allyl Carbonates: Palladium-Catalyzed Synthesis of β,γ-Unsaturated Amides and Tetrazoles

Qian Wang, Jieping Zhu, Mathias Mamboury, Guanyinsheng Qiu

The reaction of allyl ethyl carbonates with isocyanides in the presence of a catalytic amount of Pd(OAc)2 provided ketenimines through b-hydride elimination of the allyl imidoylpalladium intermediates. The insertion of the isocyanide into the p-allyl Pd co ...
