Micromechanics of oxide inclusions in ferrous alloys

Alejandra Inés Slagter

Oxide inclusions are inevitably present in steel as a direct consequence of the steelmaking process; as a result, a cubic centimetre of modern steel will generally contain about a million of these hard and brittle micrometre-sized ceramic particles. Inclus ...

Clay calcination technology: state-of-the-art review by the RILEM TC 282-CCL

Karen Scrivener, Franco Alberto Zunino Sommariva, François Henri Avet, Alastair Thomas Matthew Marsh, Mohsen Ben Haha, Shashank Bishnoi, Adrian Alujas Diaz, Anuj Parashar

The use of calcined clays as supplementary cementitious materials provides the opportunity to significantly reduce the cement industry's carbon burden; however, use at a global scale requires a deep understanding of the extraction and processing of the cla ...

Pre-bcc: A novel integrated machine learning framework for predicting mechanical and durability properties of blended cement concrete

Hisham Tarek Mohamed Hafez

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 ...

Hydration and durability of fast hardening binders incorporating supplementary cementitious materials

Sarra El Housseini

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 ...

ECO2 framework assessment of limestone powder concrete slabs and columns

Hisham Tarek Mohamed Hafez

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 ...

Report of RILEM TC 267-TRM: Improvement and robustness study of lime mortar strength test for assessing reactivity of SCMs

Karen Scrivener, Ruben Anton Snellings, Mohsen Ben Haha, Xuerun Li, Shashank Bishnoi, Pawel Tadeusz Durdzinski, Mathieu Antoni, Anuj Parashar, Yuvaraj Dhandapani

RILEM TC 267-TRM is studying tests for the reactivity supplementary cementitious materials (SCMs). In the first phase, the lime reactivity (LR) test, which is standardised in Indian standard (IS)-1727, gave promising correlations with 90-days cement mortar ...

Shear behavior of single- and triple-thickness masonry panels strengthened by bed-joint structural repointing

Ricardo Javier Serpell Carriquiry

Bed-joint structural repointing is a widely used strengthening technique in historic masonry constructions, particularly in applications where the material appearance needs to be preserved. Despite its wide use, limited research is available on the effecti ...

Towards 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 ...

The 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 ...
