Oxidation of pyrite (FeS2) and troilite (FeS) impurities in kaolinitic clays after calcination

Karen Scrivener, Franco Alberto Zunino Sommariva

Valorisation of locally available clays for producing blended cements is crucial for a widespread adoption of sustainable binders incorporating these materials. In some places, clays can be intermixed with small amounts of iron sulfides, which could eventu ...

Paper of RILEM TC 282-CCL: mineralogical characterization methods for clay resources intended for use as supplementary cementitious material

Franco Alberto Zunino Sommariva, Ruben Anton Snellings, Alastair Thomas Matthew Marsh, Adrian Alujas Diaz

To respond to the rapid introduction and development of calcined clays as supplementary cementitious material (SCM), the toolbox of characterization methods for cementitious materials requires extension to raw clay characterization. Borrowing concepts and ...

The Influence of some calcined clays from Nigeria as clinker substitute in cementitious systems

Karen Scrivener, François Henri Avet, Akindehinde Ayotunde Akindahunsi

This paper examines the possibility of the use of some clays calcined from Nigeria as partial substitutes for clinker in the production of Limestone Calcined Clay Cement (LC3). The clays were calcined in the oven at a temperature of 800 degrees C and for o ...

Basic creep and autogenous shrinkage of Limestone Calcined Clay Cement (LC3)

Julien Ston

The use of supplementary cementitious materials (SCM) to lower the clinker factor of cements is now commonplace, for it benefits performance, economics and ecology. This thesis focuses on ternary blends of limestone and calcined kaolinitic clays, two very ...

Hydration Study of Limestone Calcined Clay Cement (LC3) Using Various Grades of Calcined Kaolinitic Clays

Karen Scrivener, François Henri Avet

In this study, the influence of the calcined kaolinite content of calcined clay on the hydration of Limestone Calcined Clay Cement (LC3-50) is investigated. It is shown that with the increase of the calcined kaolinite content of the calcined clay, the clin ...

Assessing the Effect of Calcite Impurities in Clay on Optimal Dehydroxylation Parameters for Enhanced Reactivity

Karen Scrivener, Franco Alberto Zunino Sommariva

This study focused on understanding the influence of different amounts of calcite impurities (0 to 10% by mass) on the optimal parameters for clay dehydroxylation and the reactivity of the final calcined clay. A surface response experimental design was use ...

Autogenous Shrinkage and Creep of Limestone and Calcined Clay Based Binders

Karen Scrivener, Julien Ston, Adrien Jean Régis Maurice Hilaire

This study explored the delayed strains in limestone and calcined clay ternary blends. Autogenous shrinkage measurements are carried out over 2 months and compressive basic creep tests during 28 days after one month of curing. All tests are done using mixe ...

Investigation of the grade of calcined clays used as clinker substitute in Limestone Calcined Clay Cement (LC3)

François Henri Avet

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 ...

Effect of fineness in clinker-calcined clays-limestone cements

Karen Scrivener, Mathieu Antoni, Adrian Alujas Diaz, Leng Maday Vizcaino Andres

This paper looks at the effect of fineness of the different components in a blend containing 55% Portland cement, 30% calcined clay and 15% limestone. The calcined clay originates from a natural deposit in Cuba and contains less than 50% kaolinite. The par ...
