(VI) Anti-rays cement, mortar and concrete: the use of barite having an X-ray absorption properties, making Barium cement, barite mortar and Barite Concrete by barite, can replace metal grid for shielding nuclear reactor and build research, hospital etc buildings of X-ray proof.
The key difference between lightweight and heavyweight concrete is the density of the aggregate. Lightweight concrete is made using aggregate whose density is less than 2,100 kilograms per cubic yard (or 131 pounds per per cubic foot), while aggregates with greater densities give rise to so-called heavyweight concrete.
Barite or baryte is a mineral containing barium sulfate. Its name is originally derived from the Greek word "barys" meaning "heavy". This mineral belongs to the Barite Mineral Group along with anglesite, celestine and anhydrite. It has quite a beautiful appearance.

Barite is commonly used to add weight to drilling fluid. ... Contaminants in barite, such as cement, siderite, pyrrhotite, gypsum and anhydrite, can cause problems in certain mud systems and should be evaluated in any quality assurance program for drilling-mud additives.
An outgrowth of the development of nuclear energy, high-density concrete is gaining wide spread use as a shielding material to provide protection against radiation hazards. In contrast with conventional concrete weighing around 150 pounds per cubic foot, high-density concretes normally weigh from 200 to 250 pounds per cubic foot.
Hole near gauges, use proper hole cleaning techniques, pumping sweeps at TD, and perform wiper trip to shoe. Mud low viscosity, mud parameters should be tolerant of formations being drilled, and drilling fluid composition, turbulent flow - low viscosity high pump rate, laminar flow - …
Barite heavyweight additive is a barium sulfate material used to weight drilling muds and cement slurries. Typically, 85 to 90% of barite additive will pass through a 325-mesh sieve. Barite additive is effective at bottomhole temperatures (BHTs) between 80°F and 500°F (27°C and 260°C).

Dec 17, 2015· Cement slurry density can vary from 11 ppg to 18.5 ppg. The density is controlled by adjusting the amount of mix-water or additives. The cement slurry density is relatively higher than the density of drilling fluids which has to be considered when planning for cement job especially when formations with normal pore pressure trend.
Barite aggregate behaves in concrete similarly to an ordinary crushed aggregate such as limestone or basalt, and no special problems were encountered in selecting and proportioning the constituents of the concretes. Exceptionally high compressive strengths were developed by conventional barite concrete.
Portland cement's chemistry comes to life in the presence of water. Cement and water form a paste that surrounds and binds each particle of sand and stone. Through a chemical reaction of cement and water called hydration, the paste hardens and gains strength. The character of concrete is determined by the quality of the paste.
Oct 24, 2015· In applications of concrete for shielding against hazardous radiation or for being used as counterweight, as well as in various other applications that involve the use of heavyweight concrete, the most significant method of mix design involves the use of heavyweight aggregates. Concrete mixes that were produced for this work contained iron ore ...
Aggregates for Concrete bination of gravels or crushed stone with particles predominantly larger than 5 mm (0.2 in.) and generally between 9.5 mm and 37.5 mm (3⁄ 8 in. and 11⁄ 2 in.). Some natural aggregate deposits, called pit-run gravel, consist of gravel and sand that can be readily used in concrete after minimal processing. Natural ...
