Distribution of calcium carbonate in the self-healing process of microbial concrete is studied in detail, with the help of a variety of analytical techniques. The results show that carbonate deposits along the x-axis direction of the cracks. The farther from the crack surfaces of concrete matrix...
(mainly CaCO3); these include calcif-erous algae, many mollusks, echinoderms, corals, and rhizopods. Deposits of the skeletons of marine animals and plants lead to the accumulation of colossal masses of algal, coral, and other limestones, which, buried deep within the earth and mineralized, ...
mostcave deposits, many marbles and carbonatites, and some ore-bearing veins. Calcite is the stable form of calcium carbonate at most temperatures and pressures.Aragoniteis the orthorhombic (i.e., having three unequal crystallineaxesat right angles to one another) form of calcium carbonate. Though...

Whitish deposits of calcium carbonate, CaCO 3, frequently develop on Portland cement concrete and on masonry units, including brick and tile, which have been bonded with Portland cement. These surface deposits are termed efflorescence and are most frequently encountered in new or recent construction....
