Going Below 50% Clinker Factor in Limestone Calcined Clay Cements (LC3): A Comparison with Pozzolanic Cements from the South American Market
Karen Scrivener, Franco Alberto Zunino Sommariva
Limestone calcined clays are a promising technology as they offer similar performance to OPC from 7 days onwards, while enabling a reduction of the clinker content of 50%. In some regions of the world like South America, pozzolanic cements (i.e., blended c ...
SPRINGER INTERNATIONAL PUBLISHING AG2023Pre-bcc: A novel integrated machine learning framework for predicting mechanical and durability properties of blended cement concrete
Partially replacing ordinary Portland cement (OPC) with low-carbon supplementary cementitious materials (SCMs) in blended cement concrete (BCC) is perceived as the most promising route for sustainable concrete production. Despite having a lower environment ...
ELSEVIER SCI LTD2022Resistance of cementitious materials to sulfate attack: quantifying performance with a reliable unidirectional approach
Depending on the environmental conditions, concrete materials can come into contact with sulfate ions which are widely present in rivers, underground water, sewers, seawater and soil. Sulfates can react with the cement paste in concrete and cause damage wh ...
EPFL2022ECO2 framework assessment of limestone powder concrete slabs and columns
Producing limestone powder requires comparably far less energy than the production of ordinary Portland cement (OPC), making it a promising sustainable solution for partial replacement of OPC in concrete. Lower production energy could be translated into lo ...
ELSEVIER2022Reactive dicalcium silicate binders: Microstructure and transport properties
The calcium silicate hydrates (C-S-H) are without doubt one of the most important hydration products in a hardened cement paste. Giving the complexity of the microstructure that forms by hydration of ordinary Portland cement (OPC) and the more recently use ...
EPFL2022Microstructural 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 LTD2022Towards tailored cement-based materials with ground calcium carbonates
Emmanuel Denarié, Lionel Sofia
Proportioning the dosage of Ground Calcium Carbonates (GCC) in cementitious materials, beyond current normative levels, is one of the most promising ways towards sustainability of mortar and concrete technology. Performance parameters such as the water/bin ...
2021Characterization of interfacial transition zone in concrete prepared with carbonated modeled recycled concrete aggregates
Treatment by accelerated carbonation has been widely studied to enhance the quality of recycled concrete aggregates (RCA) and hence the performance of new concrete produced with the RCA. This is often ascribed to the densification of RCA. This study invest ...
PERGAMON-ELSEVIER SCIENCE LTD2020The 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 ...
SPRINGER2020Concrete Performance of Limestone Calcined Clay Cement (LC3) Compared with Conventional Cements
Karen Scrivener, Lionel Sofia, François Henri Avet
This study aims to demonstrate the robustness of concrete made of limestone calcined clay cement (LC3). Two campaigns were carried out using 375 kg.m(-3) and 500 kg.m(-3) of binder and targeting plastic and self-placing workability, respectively. The concr ...
