Impact of sodium gluconate on white cement-slag systems with Na2SO4

Sodium gluconate has been shown to compensate the impact of alkalis on the long term strength development of cement pastes. This work studies the impact of sodium gluconate combined with Na2SO4 on the microstructural development of white cement-slag system ...

Concrete Performance of Limestone Calcined Clay Cement (LC3) Compared with Conventional Cements

Karen Scrivener, François Henri Avet, Lionel Sofia

This study aims to demonstrate the robustness of concrete made of limestone calcined clay cement (LC3). Two campaigns were carried out using 375 kg.m(-3) and 500 kg.m(-3) of binder and targeting plastic and self-placing workability, respectively. The concr ...

Reactivity tests for supplementary cementitious materials: RILEM TC 267-TRM phase 1

Karen Scrivener, Mohsen Ben Haha, Xuerun Li, Ruben Anton Snellings, Mathieu Antoni

A primary aim of RILEM TC 267-TRM: Tests for Reactivity of Supplementary Cementitious Materials (SCMs) is to compare and evaluate the performance of conventional and novel SCM reactivity test methods across a wide range of SCMs. To this purpose, a round ro ...

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 ...

The pore solution of blended cements: a review

Ruben Anton Snellings

This paper is the work of working group 3 of the RILEM Technical Committee on Hydration and Microstructure of Concrete with SCM (TC 238-SCM). The pore solution is an essential but often overlooked part of hydrated cements. The composition of the cement por ...

Alkali Activation of AOD Stainless Steel Slag Under Steam Curing Conditions

Ruben Anton Snellings

Crystalline argon oxygen decarburization slag, in powdery form, was investigated for its hydration potential by alkali activation and curing at 80 degrees C. Na-silicate and K-silicate of the same modulus were used as activators. Isothermal calorimetry at ...

Impact of the supplementary cementitious materials on the kinetics and microstructural development of cement hydration

Elise Marie Jeanne Berodier

Supplementary cementitious materials (SCMs) are currently used to replace part of the clinker to reduce the environmental impact of cement and to favor the use of local materials. Two representative SCM have been used in this work: slag and fly ash. Each o ...

Degradation mechanism of slag blended mortars immersed in sodium sulfate solution

Wei Sun, Karen Scrivener

Additions of slag are usually considered to give cementitious materials which perform well in sulfate bearing environments. This paper compares the deterioration of slag cement blends to those of plain Portland cement and demonstrates that this occurs more ...

The Effect of Mg on Slag Reactivity in Blended Cements

Karen Scrivener, Ruben Anton Snellings

Blast-furnace slags are widely used as supplementary cementitious materials in blended cements because of their relatively high reactivity. This study describes the effect of substituting Ca by Mg on the reactivity of synthetic glass with similar compositi ...
