Testing and nonlinear modelling of industrialized light-frame wooden diaphragms including optimized nailing and nonstructural sheathing

This article presents the outcomes of a large project towards the investigation of the lateral performance of full-scale industrialized light-frame wooden diaphragms. 10 full-scale diaphragms of 3.6 m by 2.4 m were tested under in-plane lateral loading (mo ...

The impact of calcite impurities in clays containing kaolinite on their reactivity in cement after calcination

Karen Scrivener, Franco Alberto Zunino Sommariva, Emmanuelle Boehm Courjault

The use of supplementary cementitious materials as a partial replacement for Portland cement is the most effective way to reduce the carbon footprint of the concrete industry. Raw clays containing kaolinite (kaolin) are promising substitute materials. In t ...

Chemical shrinkage of ye'elimite with and without gypsum addition

Karen Scrivener, Mohsen Ben Haha, Frank Bullerjahn

Ye'elimite (Ca4Al6O12SO4 or C(4)A(3)S) is the main hydraulic mineral present in calcium sulphoaluminate cement (CSA). Its reaction is responsible for the (early) hydration and associated cement properties such as the chemical shrinkage. This paper discusse ...

Influence 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. ...

Expansion mechanisms in calcium aluminate and sulfoaluminate systems with calcium sulfate

Karen Scrivener, Christophe Gosselin, Julien Bizzozero

The long-term expansion of calcium aluminate cement and calcium sulfoaluminate cement in the presence of added gypsum has been studied for samples cured under water. Progressively higher amounts of gypsum were added to the CAC or CSA and it was found that ...

Hydration of C(3)A-gypsum systems

Karen Scrivener, Alexandra Quennoz

Hydration of C(3)A-gypsum systems with different gypsum additions was investigated in terms of the phase assemblage, kinetics and microstructural development. The second stage of the reaction, which begins after the depletion of gypsum, was of particular i ...

Cement substitution by a combination of metakaolin and limestone

Karen Scrivener, Mathieu Antoni, John Espen Rossen

This study investigates the coupled substitution of metakaolin and limestone in Portland cement (PC). The mechanical properties were studied in mortars and the microstructural development in pastes by X-ray diffraction, thermogravimetry analysis, mercury i ...

Hydration of C3A with Calcium Sulfate Alone and in the Presence of Calcium Silicate

Alexandra Quennoz

Tricalcium aluminate (C3A) is one of the main constituents of Portland cement. Even though it represents less than 10% of the total composition, its strong reaction with water can lead to a rapid setting, called flash set. Gypsum is added to regulate this ...
