Decarbonization potential of steel fibre-reinforced limestone calcined clay cement concrete one-way slabs
This study deals with a comparison of the environmental performance of one-way slabs utilizing steel fibrereinforced limestone calcined clay cement (LC3) concrete with the control case of Ordinary Portland cement concrete. The experimental program constitu ...
Elsevier Sci Ltd2024Additively manufactured steel reinforcement for small scale reinforced concrete modeling: Tensile and bond behavior
Christian Leinenbach, Rafal Wróbel
Small scale (1:30-1:40) Reinforced Concrete is useful for centrifuge testing. However, manufacturing the reinforcing cages by hand at this scale is practically difficult. This paper suggests that small scale reinforcement can be manufactured using a metal ...
Elsevier Sci Ltd2024Influence 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 ...
SPRINGER2023Going 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 AG2023Data-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 ...
ELSEVIER2023Atomic-Level and Surface Structure of Calcium Silicate Hydrate Nanofoils
Karen Scrivener, Paul Bowen, Aslam Kunhi Mohamed, Ziga Casar
Deciphering the calcium silicate hydrate (C-S-H) surface is crucial for unraveling the mechanisms of cement hydration and property development. Experimental observations of C-S-H in cement systems suggest a surface termination which is fundamentally differ ...
AMER CHEMICAL SOC2023Unidirectional penetration approach for characterizing sulfate attack mechanisms on cement mortars and pastes
Karen Scrivener, Qiao Wang, William Wilson
Degradation of cementitious materials by sulfate ions is commonly classified into chemical and physical sulfate attack. So-called "physical" attack dominates in many field situations, but laboratory testing focuses on "chemical" attack under full-immersion ...
PERGAMON-ELSEVIER SCIENCE LTD2023Characterisation 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 LTD2023Resistance 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 ...
