Durability 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 MATERIALS2023Atomistic modeling of C-S-H: bulk and surface
By replacing part of Portland cement with so-called supplementary cementitious materials (SCMs) it is possible to reduce the CO2 footprint of the cement industry. These SCMs are commonly limestone, calcined clay, slag and fly ash. While doing so the early ...
EPFL2023Influence 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 ...
SPRINGER2023Characterisation and hydration kinetics of beta-C2S synthesised with K2SO4 as dopant
Karen Scrivener, Franco Alberto Zunino Sommariva, Shashank Bishnoi, Sreejith Krishnan
In this study, a protocol for synthesising beta-C2S using K2SO4 as a dopant has been reported. Quantitative X-Ray diffraction was used to characterise synthesised samples. It was observed that it is possible to synthesise beta-C2S with high purity (>96 wt% ...
PERGAMON-ELSEVIER SCIENCE LTD2023Hydration 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 ...
SPRINGER2022Microstructural developments of limestone calcined clay cement (LC3) pastes after long-term (3 years) hydration
Karen Scrivener, Franco Alberto Zunino Sommariva
LC3 is one of the most promising alternatives for a high-performance blended cement with a significantly lower clinker content and with potential for worldwide adoption. For this reason, understanding its long-term performance is relevant to ensure service ...
PERGAMON-ELSEVIER SCIENCE LTD2022The 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 ...
