1. Introduction. Calcium carbonate produced by biological activity (mainly by bacteria) is commonly named as biocement. This mineral is precipitated after the hydrolysis of urea by microorganisms. The precipitation of calcium carbonate occurs at high pH and is called microbially induced calcite precipitation, MICP.

Calcium carbonate is one of the most common and profuse bio mineral present all around the world. Calcium carbonate is a chemical compound having a chemical formula CaCO 3 that is extensively present in rocks, pearls, shells of microorganism and eggs .CaCO 3 is the most abundantly found mineral that is also present in the natural hard tissues like teeth and bones.

This paper discusses the advantages of the use of a novel construction nanocomposite material such as polyvinyl chloride/calcium carbonate (PVC/CaCO 3) used for the structural retrofit of building structures.The research herein compares its mechanical (tension and flexure) and blast resistance properties to typical cementitious composites and polymer …

Evolutions in the mechanical and hydraulic properties of sand samples treated are examined through the unconfined compression and permeability tests, respectively. The grout is composed mainly of urease that bio-catalyzes the hydrolysis of urea into carbon dioxide and ammonia, urea, and calcium chloride solution.

Abstract. The calcium carbonate content of 73 beach and 9 wind-blown sands was estimated by means of leaching with hydrochloric acid. The results of these analyses are tabulated and it is pointed out that north of northern North Carolina calcareous beach sands are the exception, while south of this point they are the rule.
