Summary: This study evaluated the physical and chemical effects of calcium carbonate limestone filler in mortar pastes subjected to accelerated carbonation. Results showed that a 25% filler substitution at a water/cement ratio of 0.42 achieved the best performance in terms of compression strength and water absorption. Carbonation primarily affected by the water/cement ratio rather than substitution level, consuming portlandite and forming calcite. Further studies identified additional calcium carbonate polymorphs after 28 days of accelerated carbonation.

Summary: Selenium can become toxic due to its bioaccumulation potential, but can be immobilized by the mineral calcite. The incorporation of Se into calcite can be influenced by the presence of foreign ions in aqueous solution, affecting the precipitation of different phases such as vaterite and aragonite. The aging process of calcium carbonates precipitated from solutions highly supersaturated with respect to CaCO3 and slightly supersaturated with respect to CaSeO3 & BULL;H2O showed that vaterite hosting Se had low crystallinity and the transformation to calcite was inhibited.

Summary: In this study, printable gamma-C2S slurries were developed based on the carbonation of calcium silicate, and their printability was demonstrated using extrusion-based layer deposition. The rheology of the slurry was controlled by three modifying agents, including CMC, HPMC, and PAM. The printed samples exhibited high compressive strength and inter-layer bonding strength, which can be attributed to the diffusion of carbonation reaction and densification by carbonation products. The proposed printing-carbonation synergistic enhancement technique allows for independent design and expands the diversity of geometrical designs in 3D printing structures.

Summary: The extensive use of Portland cement with a large carbon footprint has caused a significant climate crisis. The proportions of β-C2S and γ-C2S in C2S paste are positively correlated with compressive strength and carbonation degree. An optimum value of compressive strength (54.4 MPa) and carbonation degree (36.7%) can be achieved when β-C2S is 60 wt% and γ-C2S is 40 wt%.

Summary: This article presents a two-step synthesis method for synthesizing calcium carbonate using ammonium carbonate and calcium chloride as raw materials. The pH of the mineralized solution was studied under different factors, such as temperature and ammonium carbonate concentration. The results showed that increasing the temperature promoted the formation of submicron calcite type calcium carbonate, while changing the concentration of ammonium carbonate had little effect on the crystal phase and size of the product.

Summary: This study investigated the application of amino acids in controlling CaCO3 crystallization in carbonation cured wollastonite composites. The use of amino acids resulted in the formation of stable ACC, vaterite, and aragonite, as well as enhanced flexural and compressive strength of the composites. These improvements were attributed to the reduced critical pore size and the formation of organic-inorganic hybrid phases in the matrix.

Summary: Calcium looping (CaL)-based solar to thermochemical energy storage is a promising option for long-term thermal energy storage in concentrated solar power generation. In this study, multi-doping of transition metals and CaCl2 was investigated to enhance the optical absorption and carbonation reactivity of synthetic CaO-based materials. The proposed materials exhibited significantly enhanced optical absorption and maintained high performance throughout multiple cycles of CaL reactions. The reaction mechanism was studied, and a salt-promoted carbonation mechanism was proposed to improve the mass transfer of Ca2+O2- to adsorbed CO2. Based on the findings, the synergistic use of CaCl2 multi-doping method for synthetic CaO designs is suggested.

Summary: This study developed a method to explore the evolution of carbonation-hydration heat using a modified isothermal calorimeter. It was found that the intensity of carbonation heat was much higher than hydration heat, and the main carbonation and hydration peak flows overlapped. However, it was possible to achieve independent carbonation-hydration flow by adjusting the prior-hydration time, water-to-cement ratio, and superplasticizer. Furthermore, prior-hydration promoted CO2 uptake by the paste and the formation of irregular graininess and rhombohedral-like calcium carbonate crystals.

Summary: Cement production emits a significant amount of CO2, contributing to global warming. However, cement's main mineral component can solidify CO2 and convert it into stable calcium carbonate, leading to the production of low-carbon building materials. This study proposes a thermodynamic model to simulate the formation of different calcium carbonate polymorphs during the carbonation of Portland cement with the addition of common stabilizer MgCl2. The developed model accurately predicts the proportion of calcium carbonate polymorphs and suggests the optimal conditions for their formation.

Summary: The corrosion inhibitory potency of two new pyrimidine-pyrazole derivatives, PPA and PPC, was evaluated for mild steel in 1 M HCl. The results showed enhanced inhibition activities with increased concentration, reaching maximal values of 91.15% and 92.39% for PPA and PPC, respectively. However, the mitigation potency decreased with increasing temperature. SEM and XPS analysis revealed that PPA and PPC adsorbed on the mild steel surface, forming a shielding layer that prevented the dissolution of the steel in the acidic solution.
