Natural cement found in industrial waste reacts with ocean water to form rocks in just 35 years, instead of millions.

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 ...

Add a description, image, and links to the calcite-demo topic page so that developers can more easily learn about it.

These samples were subjected to large-area scanning electron microscopy, energy-dispersive x-ray spectroscopy ... the Tomb of Caecilia Metella, where cracks in the concrete have been filled with ...

Isolating fungi from alkaline soils and confirming their calcite precipitation through XRD and field emission scanning electron microscopy (FESEM) expands the scope of microorganisms in bio-cement ...

The developed high-speed three-dimensional scanning force microscopy enabled the measurement of 3D force distribution at solid-liquid interfaces at 1.6 s/3D image. With this technique, 3D hydration ...

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 ...

with similar enhancements observed in Flexus-treated concrete. The presence of calcite precipitation, confirmed by X-ray diffraction and scanning electron microscopy, contributes to crack healing, ...

An example of this is Portland cement, an essential element in the mixture of water and aggregates that make concrete, which allows the creation of both load-bearing and decorative elements.

Over geological time, these calcareous deposits compact and cement together, forming extensive limestone beds. Notably, limestones are not just rich in calcite; they are also significant as ...
