    In this study, the expansion behavior of cement materials after high-temperature heating and water immersion was observed experimentally. Two experiments were conducted using mortar specimens with different sand-to-cement ratios subjected to different high-temperature histories up to 1000 °C. In Case 1, the specimens were immersed in water after high-temperature heating and then cooled naturally; in Case 2, the specimens were immersed in water at high temperatures without the cooling process. Based on the results, it was confirmed that lime expansion due to the rehydration of CaO by heating occurred in Case 1. In contrast, dynamic continuous explosive spalling occurred in Case 2 because of water penetration into the specimen at a high temperature. The explosive spalling in water observed in Case 2 is a phenomenon that has not been reported to date. Possible failure mechanisms for lime expansion and continuous expansive spalling in water are suggested.

    Understanding the drying shrinkage of low Ca/Si ratio cement pastes is crucial for promoting the use of low-clinker ratio cementitious materials and reducing the environmental impact of cement production. We prepared well-hydrated cement paste samples with various fly ash replacement and water-to-cement ratios. The long-term drying shrinkage was measured by 1 mm-thick samples. Results showed that fly ash containing samples exhibited lower shrinkage and the irreversible part of drying shrinkage was less compared to those without fly ash. Chemical composition analysis of the calcium aluminate-silicates hydrate (C-A-S-H) was conducted using X-ray diffraction (XRD) and energy-dispersive X-ray spectroscopy (EDS). Additionally, water vapor sorption isotherms and proton nuclear magnetic resonance (1H NMR) relaxometry were used to determine specific surface area and pore structure. By analyzing these results in conjunction with the C-A-S-H model, we attributed the reduced and more reversible drying shrinkage in fly ash cement to lower Ca ion amounts in the interlayer space and fewer trapped larger pores.

    To understand the microstructural changes in the hardened cement paste during the drying, hardened white Portland cement pastes were D-dried or dried under 11, 33, 40, and 75% relative humidity, and then, pastes were impregnated with 2-propanol or water under vacuum. Measurement of 1H NMR relaxometry was employed for the pastes before and after impregnation, and the full-scale microstructural changes of the hardened cement paste after drying were successfully visualized. It was observed that the volume of the coarse pores outside the agglomeration of calcium-silicate-hydrate (C-S-H) increased, and the volume of the C-S-H interlayer spaces and gel pores decreased as the drying relative humidity decreased. Thus, it was evidenced that interlayer space is decreasing during drying. It was also confirmed that 2-propanol can enter some of the interlayer space of C-S-H after harsh drying.

    Interfacial transition zone (ITZ) is a weak part around aggregate in concrete, which could threaten the macroscopic properties of concrete such as strength, stiffness, deformation, and durability. However, it is difficult to quantify the ITZ effect on the macroscopic behavior of concrete only by experimental methods due to the tiny thickness of ITZ. This study employed finite element (FE) method to investigate the ITZ effect on the elastic modulus, creep, and shrinkage. A mesoscale three-phase FE model consisting of homogeneous matrix phase, aggregates and ITZ around them was developed for concrete in this study. The influences of the FE model dimension and the meshing size on the calculated results were first discussed. Then the influence of the thickness, viscoelasticity and shrinkage of ITZ on the macroscopic properties of concrete were evaluated based on the FE calculation and grey relation analysis. Finally, the measured elastic modulus, creep and shrinkage of concrete with different contents of clay on coarse aggregates were used to validate the FE model. It is found that the calculated results of the two-dimensional (2D) FE model are in good agreement with those of the three-dimensional (3D) FE model under the linear viscoelastic assumption. The meshing size has a minor effect on the calculated results when it is 0.2–2 times of the ITZ thickness. The influence of ITZ properties on the macroscopic properties of concrete will become more significant as the ITZ thickness increases. Moreover, the elastic modulus of ITZ has a greater impact on the effective properties of concrete than the thickness, creep, and shrinkage of ITZ. The findings in study can contribute to a better understanding of ITZ effect on the macroscopic properties of concrete and provide references to the reasonable consideration of ITZ in numerical studies.

    In structures where prestressing plays a vital role, predicting stress losses is essential to demonstrate their robustness. After presenting the equations of the next-generation Eurocode 2 (EC2), the delayed deformations of the containment vessels of EDF nuclear power plants are predicted. In the first step, the parameters of the laws are recalibrated based on the measurements of the containments, considering a temperature higher than 20 °C. The application to 17 containments allows for the definition of a safety coefficient to be applied to shrinkage and creep to ensure that the delayed deformations evaluated for the design will be conservative. In the second step, the parameters of the equations of creep and shrinkage are calibrated on laboratory results, and an analytical model using these parameters is applied to 5 containments. All the results show that it is possible to predict the behavior of prestressed structures provided that the parameters of the equations controlling the delayed deformations are calibrated either on measurements of these structures or laboratory tests. Considering the variability of concretes, safety coefficients are proposed to guarantee that the predicted deformations cover 95% of the deformations of concrete of a given strength.

    The prediction of the long-term behavior of prestressed concrete structures is important in order to assess and/or extend the service life of such structures. Here, a modelling of the delayed strains (creep and shrinkage of concrete and relaxation of steel), based on the relations of the next Eurocode 2 (EC2), is used to predict the behavior of the internal vessel of the VERCORS mock-up of a French NPP. This modelling considers the influence of the temperature and of the relative humidity (varying under service conditions). The predicted delayed strains are compared with the measurements and different hypotheses are tested to improve the prediction of the delayed strains.

    <p>セメントと水が反応してできるものはセメントペーストと呼ばれ、カルシウムシリケート水和物を主成分とし、コンクリートの結合剤の役割を果たしている。セメントの主成分のCaOは、CaCO3の分解から得られており、この時にCO2が発生する。一方、コンクリートは大気中のCO2と反応して炭酸カルシウムが生成する(炭酸化反応)。このことを利用し、コンクリート関連分野では、大気中のCO2を無機炭酸塩の形でセメント系材料に固定化し、カーボンニュートラルの達成を目指している。Wang et al. (2023)は、セメントペーストを空気中に暴露し、その前後のペースト中の放射性炭素(14C)濃度を求めることによって、大気CO2を固定した量が評価できることを明らかにした。この評価方法を今後、実際のコンクリートに適用するためには、コンクリート全体の14C初期値が明らかになっている必要がある。そこで、本研究では、コンクリートに含まれるセメント、骨材、混和剤などの原材料の14C測定を行ったので、その結果を報告する。</p>
