Dolomite is a common rockforming mineral. It is a calcium magnesium carbonate with a chemical composition of CaMg (CO 3) 2. It is the primary component of the sedimentary rock known as dolostone and the metamorphic rock known as dolomitic marble. Limestone that contains some dolomite is known as dolomitic limestone.
Naturally occurring radiation can be found all around us. Radiation can be found in soils, in our air and water, and in us. Because it occurs in our natural environment, we encounter it every day through the food we eat, the water we drink, and the air we breathe. It .

Biotite is a name used for a large group of black mica minerals that are commonly found in igneous and metamorphic rocks. These include annite, phlogopite, siderophyllite, fluorophlogopite, fluorannite, eastonite, and many others. These micas vary in chemical composition but are all sheet silie minerals with very similar physical properties.

· Often it is observed, attainment of early compressive strength in concrete is a challenge. Researchers have tried various admixtures to achieve the objective. This work addresses the issue of achieving early compressive strength in concrete using a bacterium called Sporosarcina pasteurii . The bacterium is characterised with the ability to precipitate calcium carbonate in the presence of any ...
Barium sulfate is a soft crystalline solid. It is a rhombic crystal. The pure salt is white but the color of the mineral "barite" can vary between red, yellow, gray or green, depending on impurities. Its density is g/cm 3 and its refractive index is It melts around 1580 °C but decomposes above 1600 °C.
Hydration products. The products of the reaction between cement and water are termed "hydration products." In concrete (or mortar or other cementitious materials) there are typically four main types: Calcium silie hydrate: this is the main reaction product and is the main source of concrete strength. It is often abbreviated, using cement chemists' notation, to "CSH," the dashes indiing ...

Bricklayer Joseph Aspdin of Leeds, England first made portland cement early in the 19th century by burning powdered limestone and clay in his kitchen stove. With this crude method, he laid the foundation for an industry that annually processes literally mountains of limestone, clay, cement rock, and other materials into a powder so fine it will pass through a sieve capable of holding water.

effect. When complete, the evaluation identifies the hazard class(es) and associated hazard egory of the chemical. The HCS defines hazard class as the nature of a physical or health hazard,, flammable solid, carcinogen, and acute toxicity. Hazard egory means the division of criteria within each
Chewing gum is a soft, cohesive substance designed to be chewed without being swallowed. Modern chewing gum is composed of gum base, sweeteners, softeners/plasticizers, flavors, colors, and, typically, a hard or powdered polyol coating. Its texture is reminiscent of rubber because of the physicalchemical properties of its polymer, plasticizer, and resin components, which contribute to its ...
Embodied carbon is the carbon dioxide (CO2) or greenhouse gas (GHG) emissions associated with the manufacture and use of a product or service. For construction products, this means the CO 2 or GHG emission associated with extraction, manufacturing, transporting, installing, maintaining and disposing of construction materials and products.
Calcium is a silverywhite, soft metal that tarnishes rapidly in air and reacts with water. Uses. Calcium metal is used as a reducing agent in preparing other metals such as thorium and uranium. It is also used as an alloying agent for aluminium, beryllium, copper, lead and magnesium alloys.
