Data-driven optimization tool for the functional, economic, and environmental properties of blended cement concrete using supplementary cementitious materials
The need to produce more sustainable concrete is proving imminent given the rising environmental concerns facing the industry. Blended cement concrete, based on any of the prominent supplementary cementitious materials (SCMs) such as fly ash, ground granul ...
ELSEVIER2023Going 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 AG2023Resistance 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 ...
ELSEVIER2022Nanoscale modelling of ionic transport in the porous C-S-H network
To reduce the CO2 footprint of construction materials, concrete producers blend their cement with Supplementary Cementitious Materials (SCMs). SCMs such as fly ash or blast furnace slag are mostly the byproducts of other industries. And while SCMs are chos ...
EPFL2022Reactive 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 ...
2021A Contribution to the Design of Textile Reinforced Concrete Structures
The reduction of green-house gas emissions is one of the global challenges that our society is facing and the production of cement plays a major role because concrete is the most used material worldwide. For every 1000 kg of cement produced, 900 kg of CO2, ...
EPFL2020Maximizing the use of supplementary cementitious materials (SCMs) in blended cements
Partial replacement of clinker with supplementary cementitious materials (SCMs) is an effective approach to reduce CO2 emissions related to cement production. However, there is a maximum substitution level with SCMs beyond which strength decreases. The und ...
