摘要 ：
This study fabricated a kind of novel phase change microcapsules with a metal-polymer hybrid capsule shell for applying in gypsum materials to reduce building energy consumption. The microstructure, composition and thermal characteristics of the microcapsules were investigated by using techniques such as the scanning electron microscope, Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy and differential scanning calorimetry. Their impact on the thermal regulation characteristics of gypsum composite materials was also analyzed through the heating plate test and simulated room experiment. Results show the microcapsules with inner organic polymer and outer copper layer were successfully fabricated. And they exhibited a phase change temperature between 22.3 degrees C and 23.3 degrees C and latent heat between 82.2 J/g to 139.5 J/g. Meanwhile, the thermal inertia and thermal storage capacity of gypsum composites were enhanced by incorporating the final microcapsules. After heated for 40 min, the gypsum composite board with MPCM-Cu shows the ability to reduce the room temperature fluctuation. Furthermore, the thermal performance of MPCM-Cu remains stable after 250 thermal cycles. These results indicate that final microcapsules exhibit the potential for building energy conservation.

In this study, the impacts of CO2-absorbed triethanolamine solutions (TEA-CO2) on the mechanical property, phase composition and micro-structure of cement mortars were investigated. The results showed that TEA-CO2 addition increased the 1d, 3d, and 28d compressive strength by 47%, 19%, and 4%, respectively, which suggests a synergistic effect of triethanolamine and absorbed CO2 on strength development of cement mortars. The enhancement is due to TEA-CO2 accelerates hydration of aluminate and silicate phases in early age. TEA-CO2 facilitated CaCO3 formation to increase cement hydration degree and modify the pore structures. However, the hydration of silicate phases was delayed slightly by TEA-CO2 at 28d. The above results provide theoretical support for further utilization of CO2 in cementitious materials.

摘要 ：
Tertiary alkanolamines play an essential role in the hydration of cement-based materials as one of the main components of cement grinding aids and concrete admixtures. Although the field has been well-studied, the significant effects of slight variations in alkanolamine type and dosage make it imperative for researchers to fully understand alkanolamines before using them. Therefore, it is necessary to understand in detail the mechanism of different alkanolamines affecting the hydration of cement-based materials and their effects on setting and hardening. Based on the synthesis and chemical characteristics of alkanolamines, the complexation between alkanolamine and metal ions is discussed in this paper. The influence of alkanolamines on hydration of cementbased materials and the role of complexation in hydration are studied. Various properties of cement-based materials in the presence of alkanolamines are rigorously reviewed. The synergistic effects of alkanolamine and other admixtures are also considered in this review. The research findings prove that the complexation of alkanolamines plays an essential role in hydration and further interferes the microstructure and properties of the cement-based materials. Variations in the molecular structure and dosage of alkanolamines can lead to significant differences in hydration. The modification of alkanolamines at the molecular level and their use in combination with other admixtures are the future research directions. The working mechanism of alkanolamines in the hydration process of cement-based materials still needs to be further explored.

摘要 ：
In this paper, the strength development of a pure steel slag (SS) system with various concentrations of N,N,N ',N '-Tetrakis-(2-hydroxyethyl) ethylenediamine (THEED) was investigated. The hydration kinetics, pore structure and microstructure of SS pastes with and without THEED were characterized to underscore the working mechanism of THEED. Results show that THEED additions significantly increase the 3, 7 and 28 days compressive strength of hardened SS pastes. The enhancement effect increases with the dosage of THEED. At a concentration of 2000 ppm, THEED increased the compressive strength by 733%, 665%, and 545% at 3, 7 and 28 days, respectively. It is confirmed that THEED additions improve the hydration degree of SS by accelerating hydration of the aluminum phase (C3A, PDF-38-1429; C12A7, PDF-48-1882) and C2F,( PDF 38-0408) to generate Mc (PDF-41-0219) and Pa (PDF-30-0222) in the presence of CaCO3. Also, the hydration degree of silicates is increased by THEED. In this way, THEED additions refine the pore structure of hardened SS paste by increasing the pore volume with a diameter below 300 nm to achieve enhancement. The chelating effect of THEED results in promoting dissolution of SS, which provides the driving force for accelerating SS hydration.

摘要 ：
Steel slag (SS) as a supplementary cementitious material has low cementitious activity. Diethanol-isopropanolamine (DEIPA) is an organic admixture that can enhance the cementitious activity of cementitious materials. This work aimed to investigate the hydration characteristics of SS under the complexing of DEIPA. The hydration process of SS, the complexation of DEIPA with metal ions, and the dissolution process of C(3)A and C3S in the presence of DEIPA were systematically investigated. The results showed that DEIPA enhanced the hydration of aluminate (C(3)A and C(12)A(7)), ferrate (C2F) and silicate phases (C3S and C2S), which formed a large amount of monocarboaluminate, paraalumohydrocalcite and C-S-H gels. In the early stages of hydration, the hydration products were mainly C-S-H gels, monocarboaluminate and paraalumohydrocalcite, and in the later stages of hydration, the hydration products were mainly C-S-H gels, paraalumohydrocalcite. The monocarboaluminate may be transformed to paraalumohydrocalcite at a later stage. This hydration-promoting effect was related to the complexation of DEIPA. DEIPA facilitated the dissolution of mineral phases and the precipitation of complexed metal ions by complexing with metal ions. The stronger complexation of Al3+ by DEIPA made it more solubilizing for C(3)A. As a result, more aluminum-containing hydration products were formed. The weaker complexation of Ca2+ by DEIPA made it a weaker solubilizing for C3S, which also led to a weaker promotion of silicate hydration by DEIPA. The solubilization of DEIPA to minerals enhanced the cementitious activity of SS, which ultimately led to the increase in the compressive strength of the hardened SS paste at each age.

摘要 ：
Low-heat Portland cement (LHPC) is an environmentally friendly, low-carbon cementitious material. However, its limited early mechanical properties significantly restricts its applications. This work aimed to improve the early mechanical properties of LHPC through the synergistic effect of diethanol-isopropanolamine (DEIPA) and gypsum (CaSO42 H2O). The research investigated the effects of DEIPA and gypsum on the early mechanical properties, hydration kinetics, pore solution, hydration products, pore structure, and microstructure of LHPC. The results demonstrated that the addition of 0.03 % DEIPA alone (3D group) increased the compressive strength of LHPC at 1d but reduced the compressive strength at 3d and 7d. When 0.03 % DEIPA and 2 % gypsum (3D+2 G group) were co-added, the compressive strength of LHPC was significantly improved. The compressive strength of LHPC at 3d and 7d reached 23.0 MPa and 31.7 MPa, respectively, which were 8.49 % and 12.01 % higher than those of the reference group (REF group). When 0.03 % DEIPA and 3 % gypsum (3D+3 G group) were co-added, the compressive strength of LHPC at 3d and 7d increased to 23.5 MPa and 31.4 MPa, respectively, which were 10.85 % and 10.95 % higher than that of the REF group. After DEIPA and gypsum were co-added, the hydration shoulder peak of LHPC paste appeared later and broader compared with the 3D group, with a significant increase in cumulative heat release over 3d. At 3d and 7d of hydration, after co-adding DEIPA and gypsum, the amount of portlandite (CH) generated increased compared with the 3D group, the content of chemically bound water (CBW) significantly increased, and the degree of hydration significantly improved. The addition of gypsum further enhanced the effect of DEIPA on promoting the hydration of the ferrite phase (C(4)AF) in the LHPC paste. It alleviated the inhibitory effect of DEIPA on C3S hydration, accelerated the formation of hydration product monosulfoaluminate (AFm), optimized pore size distribution, and densified the microstructure, effectively improving the early mechanical properties of LHPC. This study provides a new approach to enhance the early reactivity of LHPC.
