The impact of calcite impurities in clays containing kaolinite on their reactivity in cement after calcination

Karen Scrivener, Franco Alberto Zunino Sommariva, Emmanuelle Anne 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 ...

Characterisation and hydration kinetics of beta-C2S synthesised with K2SO4 as dopant

Karen Scrivener, Franco Alberto Zunino Sommariva

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% ...

The Challenge of Grinding Ternary Blends Containing Calcined Clays and Limestone

Karen Scrivener, Franco Alberto Zunino Sommariva

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 ...

Towards the Design of an Industry-Suitable Technique to Assess Overcalcination of Kaolinitic Clays

Karen Scrivener, Franco Alberto Zunino Sommariva

It is well known that kaolinite dehydroxylate between 600 and 850 °C, and the maximum reactivity is achieved for calcination temperatures of about 800 °C. From an industrial perspective, controlling undercalcination is an easy task, as XRD or TGA could be ...

Hydration and phase assemblage of limestone calcined clay cements (LC3) with clinker content below 50 %

Jinfeng Sun, Karen Scrivener, Franco Alberto Zunino Sommariva

Limestone calcined clay cement (LC3) is a promising material for producing cement with low CO2 emissions and properties similar to, or superior to, those of Portland cement (PC), but at 50 % clinker content (LC3-50). In many applications, lower strengths t ...
