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 ...

Properties and occurrence of clay resources for use as supplementary cementitious materials: a paper of RILEM TC 282-CCL

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

The use of clays as resource of supplementary cementitious materials (SCMs) for a new generation of low-carbon cements and concretes is currently the subject of intense research efforts. To this purpose, a large number of clay resources have been explored, ...

Development of a new rapid, relevant and reliable (R-3) test method to evaluate the pozzolanic reactivity of calcined kaolinitic clays

Karen Scrivener, Ruben Anton Snellings, Mohsen Ben Haha, François Henri Avet, Adrian Alujas Diaz

The present paper introduces a new rapid, relevant and reliable (R-3) test to predict the pozzolanic activity of calcined clays with kaolinite contents ranging from 0 to 95%. The test is based on the correlation between the chemical reactivity of calcined ...

Pozzolanic reactivity of low grade kaolinitic clays: Influence of calcination temperature and impact of calcination products on OPC hydration

Karen Scrivener, Adrian Alujas Diaz, Rodrigo Fernandez Lopez

The influence of thermal activation temperature in the pozzolanic reactivity of low grade kaolinitic clay and the impact of calcination products in OPC hydration are assessed in this paper. The raw material, with approximately 40% kaolinite and 40% of 2:1 ...

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 ...
