Calcite even has medicinal value as both a supplemental source of calcium and as an antacid. Calcite's ready reaction with dilute acids not only serves to identify its presence in geological samples, but can neutralize excess stomach acids that cause discomfort! Even the schoolroom is not devoid of calcite.
powder can be used as a filler in concrete and paving materials and helps to reduce total void content in concrete. Marble powder can be used as an admixture in concrete, so that strength of the concrete can be increased. Marble dust is mixed with concrete, .
Creating concrete . If a concrete powder block comes into contact with water or lava, it will solidify into a block of concrete. Specifically, the block has to be placed into, next to, or fall into flowing water/lava or a water/lava source block. It will not solidify in midair falling past water/lava.

limestone is heated nearly to its fusion temperature to drive off carbon dioxide from the calcite according to the simple reaction CaCO. 3 =CO. 2 + CaO. Lime is an alkaline, white powder that is employed in the manufacture of glass, paper, masonry mortar, whitewash, and many other products.
Jun 02, 2014· Portland-limestone cement (PLC) has comparable performance properties to ordinary portland cement but improves the environmental performance of concrete. PLC has been used in the United States on a limited scale in accordance with ASTM C1157 for several years, but it is still considered a relatively new technology.
High-grade optical calcite was used in World War II for gun sights, specifically in bomb sights and anti-aircraft weaponry. Also, experiments have been conducted to use calcite for a cloak of invisibility. Microbiologically precipitated calcite has a wide range of applications, such as soil remediation, soil stabilization and concrete repair.
Limestone, mainly consisting of calcite, is a permitted additive to Portland cements often up to a 5 wt.% limit. It is shown by experiment and calculation that much, if not all, of this calcite is reactive and affects the distribution of lime, alumina and sulfate and thereby alters the mineralogy of hydrated cement pastes.

mechanical properties of concrete. Dolomite powder has some similar characteristics of cement. The replacement percentages tried were 0%, 5%, 10%, 15% and 20% by weight of cement. The compressive, split tensile and flexural strengths of concrete with dolomite powder were compared with those of the reference specimens.
Calcite Powder is a natural form of Calcium Carbonate with extremely high whiteness, purity and free flowing in nature. White Calcite Powder is widely used in plastics as filler, due to its high dispersibility, low oil absorption, high impact resistance, smooth surface finish, easy processing, compatibility with polymers and other organic additives and excellent dimensional stability.
