Characterisation and hydration of ye'elimite containing cements

Frank Bullerjahn

Calcium sulphoaluminate cements (CSA) with the main phase yeâelimite are a promising class of non-Portland cements which are gaining increasing interest from the cement industry. However, the hydration kinetics of CSA cements varies strongly, even for ce ...

Outcomes of the RILEM round robin on degree of reaction of slag and fly ash in blended cements

Karen Scrivener, Barbara Lothenbach, Mohsen Ben Haha, Pawel Tadeusz Durdzinski

Working group 2 of the RILEM TC 238-SCM undertook a comparison of laboratories and techniques for the quantification of the degree of reaction of supplementary cementitious materials in blended cements. A common set of binary pastes of Portland cement with ...

The pore solution of blended cements: a review

Barbara Lothenbach, 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 ...

Atomistic Simulations of Silicate Species Interaction with Portlandite Surfaces

Paul Bowen, Sandra Caroline Galmarini, Aslam Kunhi Mohamed

Portlandite (Ca(OH)(2), CH) is the second most abundant hydrate formed in the reaction of Portland cement with water, making it an important component in the built environment. Formation of CH is closely linked to the growth of the main hydrate phase, calc ...

Impact of alkali salts on the kinetics and microstructural development of cementitious systems

Berta Mota Gassó

Supplementary cementitious materials (SCM) lower the environmental impact of cement and concrete but react more slowly than Portland cement, which therefore limits the levels of substitution possible as reasonable early strengths are necessary. One of the ...

EPFL2015

Cement hydrates and their chemically bound water content are sensitive to changes in relative humidity (RH) and temperature. This may cause specific solid volume changes affecting dimensional properties of hydrated cement paste such as shrinkage, swelling ...

Methods to determine hydration states of minerals and cement hydrates

Karen Scrivener, Thomas Matschei, Mahsa Saeidpour

This paper describes a novel approach to the quantitative investigation of the impact of varying relative humidity (RH) and temperature on the structure and thermodynamic properties of salts and crystalline cement hydrates in different hydration states (i. ...

Pergamon-Elsevier Science Ltd2014

Calcium aluminate cements (CAC) are often used in combination with calcium sulfate and Portland cement for special applications where rapid setting, rapid drying and shrinkage compensation are required. A growing fraction of the clinker, which has the high ...

Expansion mechanisms in calcium aluminate and sulfoaluminate systems with calcium sulfate

Karen Scrivener, Christophe Gosselin, Julien Bizzozero

The long-term expansion of calcium aluminate cement and calcium sulfoaluminate cement in the presence of added gypsum has been studied for samples cured under water. Progressively higher amounts of gypsum were added to the CAC or CSA and it was found that ...

Investigation of cement substitution by blends of calcined clays and limestone

Mathieu Antoni

This thesis investigates the replacement of Portland cement by addition of high amounts of calcined clays and limestone. Such ternary blends can become more ecological and economical binders to answer the worldwide housing shortage. It could be demonstrate ...
