Rapid screening tests for supplementary cementitious materials: past and future

Karen Scrivener, Ruben Anton Snellings

Rapid screening tests for supplementary cementitious materials (SCMs) have been in use for over 150 years. Over the years a multitude of methods have been put forward to predict the strength development of SCMblended mortars and concrete. This paper summar ...

Use of X-ray diffraction to quantify amorphous supplementary cementitious materials in anhydrous and hydrated blended cements

Karen Scrivener, Ruben Anton Snellings

The content of individual amorphous supplementary cementitious materials (SCMs) in anhydrous and hydrated blended cements was quantified by the PONKCS [1] X-ray diffraction (XRD) method. The analytical precision and accuracy of the method were assessed thr ...

The Rise of Portland Cements

Karen Scrivener, Ruben Anton Snellings

This chapter tells the story of Portland cement, from its invention in the tured mineral product. The success story of Portland cement is rooted in the unique combination of the abundance of its raw materials, the reactivity of the high-temperature clinker ...

Rapid, Robust, and Relevant (R3) Reactivity Test for Supplementary Cementitious Materials

Karen Scrivener, François Henri Avet, Xuerun Li, Ruben Anton Snellings

Although supplementary cementitious materials (SCMs) are now commonly accepted and widely used, consensus has not been reached for methods to test their chemical reactivity. A multitude of test methods exist but often fall short on one or more of the key f ...

Properties and pozzolanic reactivity of flash calcined dredging sediments

Ruben Anton Snellings, Pawel Tadeusz Durdzinski

Dredging of ports, harbours and waterways generates vast amounts of sediments that find few applications and need to be disposed of. In the port of Antwerp, Belgium, each year 450,000 t (dry matter) of dredging sediments are mechanically dewatered and stoc ...

Pozzolanic activity of mechanochemically and thermally activated kaolins in cement

Karen Scrivener, Ruben Anton Snellings, Mohammadhadi Kazemi Kamyab

This paper reports on the mechanochemical activation by intensive grinding as an alternative way to produce pozzolanically reactive metakaolin. The physicochemical properties, pozzolanic reactivity and impact on cement hydration of mechanochemically and th ...

Fly ash as an assemblage of model Ca-Mg-Na-aluminosilicate glasses

Karen Scrivener, Ruben Anton Snellings, Cyrille Dunant, Mohsen Ben Haha, Pawel Tadeusz Durdzinski

Model Ca-Mg-Na-aluminosilicate glasses based on compositions found in a calcareous fly ash were synthesised and their reactivity assessed in NaOH solution and in Portland cement paste. It was found that the reactivity followed the same trend in both system ...
