Abstract

Time-Domain Nuclear Magnetic Resonance (TD-NMR) of {sup 1}H nuclei is used to monitor the maturation up to 30 days of three different endodontic cement pastes. The 'Solid-liquid' separation of the NMR signals and quasi-continuous distributions of relaxation times allow one to follow the formation of chemical compounds and the build-up of the nano- and subnano-structured C-S-H gel. {sup 1}H populations, distinguished by their different mobilities, can be identified and assigned to water confined within the pores of the C-S-H gel, to crystallization water and Portlandite, and to hydroxyl groups. Changes of the TD-NMR parameters during hydration are in agreement with the expected effects of the different additives, which, as it is known, can substantially modify the rate of reactions and the properties of cementitious pastes. Endodontic cements are suitable systems to check the ability of this non-destructive technique to give insight into the complex hydration process of real cement pastes.

Effect of hydration temperature on the solubility behavior of Ca-, S-, Al-, and Si-bearing solid phases in Portland cement pastes

Journal Article Thomas, Jeffrey; Rothstein, David; Jennings, Hamlin; ... - Cement and Concrete Research

The concentrations of Ca, S, Al, Si, Na, and K in the pore solutions of ordinary Portland cement and white Portland cement pastes were measured during the first 28 d of curing at temperatures ranging from 5-50 deg. C. Saturation indices with respect to solid phases known to form in cement paste were calculated from a thermodynamic analysis of the elemental concentrations. Calculated saturation levels in the two types of paste were similar. The solubility behavior of Portlandite and gypsum at all curing temperatures was in agreement with previously reported behavior near room temperature. Saturation levels of both ettringite andmore »« less

A thermodynamic approach to the hydration of sulphate-resisting Portland cement

Journal Article Lothenbach, Barbara; Wieland, Erich - Waste Management

A thermodynamic approach is used to model changes in the hydrate assemblage and the composition of the pore solution during the hydration of calcite-free and calcite-containing sulphate-resisting Portland cement CEM I 52.5 N HTS. Modelling is based on thermodynamic data for the hydration products and calculated hydration rates for the individual clinker phases, which are used as time-dependent input parameters. Model predictions compare well with the composition of the hydrate assemblage as observed by TGA and semi-quantitative XRD and with the experimentally determined compositions of the pore solutions. The calculations show that in the presence of small amounts of calcitemore »« less

Effects of porosity on leaching of Ca from hardened ordinary Portland cement paste

Journal Article Haga, Kazuko; Sutou, Shunkichi; Hironaga, Michihiko; ... - Cement and Concrete Research

Aiming at evaluating the effects of porosity in hardened cement paste on dissolution phenomena, we prepared hardened ordinary Portland cement (OPC), with variation in pore volume, and then leached them in deionized water. It was found that the bulk density and pore volume were affected by the dissolution of portlandite. The larger the pore volume of the sample, the more rapidly portlandite is dissolved. An electron probe microanalysis (EPMA) performed on the cross-section of the solid phase showed the 'portlandite (CH) dissolution front'. As the leaching period became longer, the CH dissolution front shifted towards the inner part. In addition,more »« less

Influence of polymer on cement hydration in SBR-modified cement pastes

Journal Article Ru, Wang; Xingui, Li; Peiming, Wang - Cement and Concrete Research

The influence of styrene-butadiene rubber (SBR) latex on cement hydrates Ca(OH){sub 2}, ettringite, C{sub 4}AH{sub 13} and C-S-H gel and the degree of cement hydration is studied by means of several measure methods. The results of DSC and XRD show that the Ca(OH){sub 2} content in wet-cured SBR-modified cement pastes increases with polymer-cement ratio (P/C) and reaches a maximum when P/C is 5%, 10% and 10% for the pastes hydrated for 3 d, 7 d and 28 d, respectively. With wet cure, appropriate addition of SBR promotes the hydration of cement, while the effect of SBR on the content ofmore »« less

Calcium hydroxide saturation factors in the pore solution of hydrated portland cement fly ash pastes

Journal Article Goni, S; Lorenzo, M; Guerrero, A; ... - Journal of the American Ceramic Society

The portlandite saturation factors in the pore solution of hydrated portland cement paste and changes related to the addition of two types of fly ash have been studied. Small additions (15 wt%) of fly ash increase portlandite supersaturation at early ages, whereas larger additions reduce it, relative to the plain cement. At later ages, portlandite undersaturation is observed despite the continued presence of free portlandite in the paste as observed by SEM.
