Influence of Low- to Medium-Kaolinite Clay on the Durability of Limestone Calcined Clay Cement (LC3) Concrete
The kaolinite content is principally responsible for the durability performance of Limestone Calcined Clay Cement (LC3), which calls into question its global applicability. The clay supply has a significant impact on the LC3 system's reduced carbon footpri ...
MDPI2023Does carbon footprint reduction impair mechanical properties and service life of concrete?
Karen Scrivener, Diana Londoño Zuluaga
The aim of this study is to evaluate how much the changes in the concrete mix design, which enable carbon footprint reduction, are impacting mechanical properties and predicted service life of concrete structure. The starting point of this study was concre ...
SPRINGER2023Durability Challenges of Low-Grade Calcined Clay Opposed to High-Volume Fly Ash in General Purpose Concrete
With the decrease in availability of common supplementary cementitious materials (SCMs) such as fly ash in Europe, the search for appropriate SCMs should be dealt with locally. A com-bination of abundant low-grade calcined clay and limestone powder has pro ...
AMER SOC TESTING MATERIALS2023Oxidation 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 ...
SPRINGER2022Hydration 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 ...
SPRINGER2022The Challenge of Grinding Ternary Blends Containing Calcined Clays and Limestone
Karen Scrivener, Franco Alberto Zunino Sommariva, Juan Alberto Ribalta Quesada
The inclusion of high specific surface materials such as calcined clays in cementitious systems enhances the hydration of clinker products at very early ages, but it may also increase water demand; thus, the pursuit of a flowing concrete may demand an incr ...
MDPI2022Paper of RILEM TC 282-CCL: mineralogical characterization methods for clay resources intended for use as supplementary cementitious material
Franco Alberto Zunino Sommariva, Alastair Thomas Matthew Marsh, Ruben Anton Snellings, 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 ...
SPRINGER2022The effect of pore microstructure on strength and chloride ingress in blended cement based on low kaolin clay
Karen Scrivener, Diana Londoño Zuluaga
The objective of this study is to analyse the mechanical and durability properties of a high-performance mortars based on low grade kaolin clay and the effect of electrical conductivity and pore microstructure on the chloride penetration resistance. A tota ...
ELSEVIER2022Properties and occurrence of clay resources for use as supplementary cementitious materials: a paper of RILEM TC 282-CCL
Franco Alberto Zunino Sommariva, Alastair Thomas Matthew Marsh, Ruben Anton Snellings, 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, ...
SPRINGER2022Hydration and durability of fast hardening binders incorporating supplementary cementitious materials
The use of supplementary cementitious materials (SCMs) is widely considered the most promis-ing approach to reduce CO2 emissions relative to cement production. SCMs are not commonly present in binders used for special applications. On the other hand, due t ...
