Strontium Retention of Calcium Zirconium Aluminate Cement Paste Studied by NMR, XRD and SEM-EDS

, 2020
This work concerns the hydration mechanism of calcium zirconium aluminate as a ternary compound appearing in the CaO-Al2O3-ZrO2 diagram besides the calcium aluminates commonly used as the main constitutes of calcium aluminate cements (CACs).

Temporal effects on the micro- and nano-structural cement-slag pastes subjected to microwave curing over 7 years

Case Studies in Construction Materials
This study examines the changes in the micro- and nano-structures of microwave-cured cement and slag pastes over 7 years. The properties of aged samples were compared with those of young pastes made from the same mixtures.

Toward Stable Multivalent Metal Batteries: Understanding the Interfacial Chemistry for Magnesium and Calcium Metal Anodes

Advanced Functional Materials, Volume 36, Issue 45, 5 June 2026.
Interphase chemistry governs the stability of multivalent metal batteries. We summarize state‐of‐the‐art developments in calcium and magnesium metal batteries by focusing on the correlation among electrolytes, interphase layers, and the electrochemical performance of corresponding metal anodes.

Modifying admixtures to cement compositions produced from local raw materials

MATEC Web of Conferences, 2018
Durability of hardened cement paste depends on chemical and mineralogical composition of Portland cement. The main factor for hardened cement paste is higher content of calcium aluminate and free calcium hydroxide, binding of which into water-insoluble ...

In Vitro Evaluation of Novel Calcium Silicate‐Based and Resin‐Modified Calcium Silicate Materials: Cytocompatibility and Mineralization Potential on Human Dental Pulp Stem Cells for Pulp Repair

Microscopy Research and Technique, Volume 89, Issue 6, Page 932-947, June 2026.
This study demonstrates that Biodentine XP exhibits superior cytocompatibility, promotes odontogenic differentiation, and enhances mineralization in human dental pulp stem cells, supporting its use in regenerative endodontics. Resin‐modified materials showed lower bioactivity, highlighting the importance of material composition in pulp therapy outcomes.

Physicochemical and remineralisation properties of calcium silicate and glass ionomer cements applied in simulated caries‐affected dentine

European Journal of Oral Sciences, Volume 134, Issue 3, June 2026.
Abstract Calcium silicate‐based and glass ionomer cements are often used in caries‐affected dentine. This study investigated the remineralising and physicochemical properties of two calcium silicates and a glass ionomer cement. Human molars with Class I cavities were subjected to pH cycling to simulate caries lesions.

Co‐Calcination of Silicate or Aluminosilicate Network of Clay and Non‐Clay Minerals With NaOH: Physicochemical Insights

Journal of the American Ceramic Society, Volume 109, Issue 6, June 2026.
Effects of co‐calcination with alkali hydroxide on pure clay minerals (kaolinite, montmorillonite) and typical impure minerals (quartz, feldspar) are presented. Co‐calcining montmorillonite and quartz with sodium hydroxide improves their reactivity. Co‐calcining kaolinite with sodium hydroxide reduces its reactivity.

Superhydrophobic Calcium Aluminate Cement with Super Mechanical Stability

, 2019
In the present study, a simple and cost-effective method for the preparation of a superhydrophobic calcium aluminate cement (SCAC) with superstable mechanical stability is reported. Room-temperature vulcanized silicone rubber (RTV) is used as an internal
