Dirt stabilizers have emerged as vital devices in civil design and facilities growth, supplying a scientifically ...

“It’s already a cement-rich material. When that hydrated cement is exposed to CO2, it becomes a new mineral, in this case calcite. It’s almost returning to its original state.” His company is ...

Thus, biomineralization appears to be a promising strategy for repairing concrete construction defects through microbial activity. The most advanced use of this novel approach is ...

This has been observed in concrete from another 2,000-year-old site, the Tomb of Caecilia Metella, where cracks in the concrete have been filled with calcite. It could also explain why Roman concrete ...

Introduction: Microbial-induced calcite precipitation (MICP) involves various microorganisms, such as bacteria, fungi, and algae. This study focuses on producing bio-cement using fungal species and ...

The first mechanism — calcite cement precipitation — dominated on the top surface of slag and on the sea-facing side above the average water level. In this process, the minerals in slag ...

The mineral calcite is a calcium carbonate corresponding to the formula CaCO3 and is one of the most widely distributed minerals on the Earth’s surface. It is a common constituent of sedimentary rocks ...

Studying calcite is important as it has broad relevance in several ways. When calcium carbonate is synthesized, it transforms carbon dioxide (CO 2) into solid carbonate, the final reaction product ...

12. Expansive Cement. Expansive cement expands slightly with time and does not shrink during and after the time of hardening. This cement is mainly used for grouting anchor bolts and prestressed ...
