Coatings | Free Full-Text | Effect of Calcium Carbonate Particle Size

Polymer-based wood coatings are used for aesthetic purposes as well as to protect wood surfaces, especially under external conditions. High-hardness mineral fillers are thought to enhance the resistance of these polymer coatings to wear and scratching. However, recent studies suggest that the relatively low-hardness mineral calcite (CaCO3, …

Evidence of scawtite and tilleyite formation at ambient …

Activated calcium carbonate (a-CaCO 3) is used partially to replace Portland cement. a-CaCO 3 is comprised of nanoscale calcium carbonate, in amorphous and calcite forms, and its enhanced carbonate activity converts calcium carbonate from being an inert filler to a reactive component. Its reaction with the C–S–H phase alters the conventional …
