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 ...
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 ...
The replacement of clinker with supplementary cementitious materials (SCMs) is the most interesting solution to reduce the CO2 emissions from cement production. The abundant availability of clays, which have a sufficient amount of kaolinite content in Thai ...
The aim of this study was to understand the origin of the variation in the hydraulic reactivity of ye'elimite systems. To this end, the hydration of two clinkers, one composed mainly of synthetic stoichiometric (C(4)A(3)(S) over bar) "Y" and the other of a ...
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 ...
The aim of this thesis is to understand the mechanisms underlying the main hydration peak and later ages of alite hydration; it proposes new mechanistic models for these two stages.Alite is the main constituent of Portland Cement (PC), and is responsible ...
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 ...
The main product of Portland cement hydration is C-S-H. Despite constituting more than half of the volume of hydrated pastes and having an important role in strength development, very little is known about the factors that determine its morphology. To inve ...
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 ...
Ye'climitc (Ca4Al6O12SO4 or C(4)A(3)(S) over bar) is the main hydraulic mineral present in calcium sulfoaluminate cement (CSA). The hydration of ye'elimite is responsible for the early age cement properties. We identify 5 stages in the hydration of neat st ...
