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 Ltd2024Characterisation 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 LTD2023Going 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 AG2023Influence 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 ...
MDPI2023Unidirectional 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 LTD2023Hydration 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 ...
