Due to its high coefficient of absorption for gamma radiation and Xradiation, barium sulfate is used in concrete (barite concrete, barite cement) that screens nuclear reactors. It is contained, in addition, in numerous radioopaque substances (radioopaque barite). About 70 % of the blancfixe produced is used in coating compounds.
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 325mesh sieve. Barite additive is effective at bottomhole temperatures (BHTs) between 80°F and 500°F (27°C and 260°C).
In contrast with conventional concrete weighing around 150 pounds per cubic foot, highdensity concretes normally weigh from 200 to 250 pounds per cubic foot. Among the natural aggregates most commonly used are barite, magnetite, limonite, geothite, and ilmenite. These can be used for the lower and medium weight ranges.

Barite (BaSO 4) Barite is not normally used in cementing as a weighting agent because of its high surface area and high water demand. It is a soft, light gray, naturally occurring nonmetallic material. The specific gravity ranges from approximately to, depending on purity, and it has a Mohs hardness of to References See also
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 drillingmud additives.
Properties of heavyweight concrete produced with barite ... The barite mineral that we use in heavyweight concrete production is found widely and abundantly in Turkey. In this case, the use of barite in heavyweight concrete production is thought to be economical. Although the cost of barite is three to four times more than that of normal ...
Sep 27, 2018· Barite is also mixed with cement to make special radioactive storage containers to store radioactive materials. The leaded glasses used in computer monitors and television tubes to minimize radiation effects are made from using barite chemicals. Manufacturing of clutches of cars, trucks, and brake pads also involve the usage of this mineral.
Modern construction uses calcite in the form of limestone and marble to produce cement and concrete. These materials are easily mixed, transported, and placed in the form of a slurry that will harden into a durable construction material. Concrete is used to make .
Nov 20, 2018· Linear attenuation coefficient was significantly increased (up to 19%) by the use of barite, and thus, the attenuation thickness of reactive powder concrete was reduced for certain gammaray transmission. • The linear gammaray attenuation coefficients were increased by decreasing linear neutron attenuation coefficients.
Dec 17, 2015· Cement slurry density can vary from 11 ppg to ppg. The density is controlled by adjusting the amount of mixwater 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.
The coefficient of thermal expansion of barite concrete measured in the range of temperature of 4°C to 38°C is found about twice that of normal concrete. 4. The modulus of elasticity and poisson''s ratio of high density concrete and normal concrete are approximately the same. 5. Shrinkage of high density concrete is about 1/4 to 1/3 of the ...

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 ...
Barite that is used as an aggregate in a "heavy" cement is crushed and screened to a uniform size. Most barite is ground to a small, uniform size before it is used as a filler or extender, an addition to industrial products, or a weighting agent in petroleum well drilling mud specification barite.
