INFLUENCE OF BARITE AGGREGATE FRIABILITY ON MIXING PROCESS AND MECHANICAL PROPERTIES OF CONCRETE,Among other applications, barite is used as an aggregate in concrete or mortar to increase their density [2] and for radiological protection by absorption or diffraction of radiation [3, 4],surficial aspect and X‐Ray diffraction of Barite.

2012-10-23· All the mortars were proportioned with an aggregate-binder ratio of 2.5 (by volume) and water–binder ratio of 0.45. Twenty-five percent of the total binder was fly ash. The mix design parameters of the mortars were kept constant except that different types of fine aggregate were used. The details of the mix proportions are shown in Table 2.

The barite mortar showed the lowest detected dose value, which represented about an 88.3% and 92.2% reduction as compared to red brick and sand mortar, respectively. The results are consistent with others [1,8]. This has proven that the barite aggregate is particularly well-suited for use in cement mortar for radiation shielding applications.

2012-10-23· The barite mortar showed the highest density amongst all the samples examined, followed by FG-U mortar, FG-T mortar, with a density of 3043, 2546 and 2472 kg/m 3, respectively. This can be attributed to the high molecular weight of BaSO 4 in barite and lead oxide metal contained in the CRT funnel glass, which increased the specific gravity of aggregate and consequently increased the mortar

2017-11-01· The measurements of the spectra were checked with the detector placed at 340 cm from the focal point, and the barite mortar plates or a set of them were positioned at 50 cm from the focal point.Reference X-ray qualities were used as recommended by ISO ().By integrating the incident spectrum and the transmitted spectrum over selected width of the photo peak, incident intensity I 0

The optimum mix proportion to produce concrete density of 2300 2400 kg/m3 is 1:2:4. The water The water to cement ratio is maintained between 0.5 and 0.55 to produce moderate slump and workability.

2019-03-01· Five mortar mixtures have been prepared with different proportions of additives ranging from 0% to 30% of the cement mass by weight. Evaluation of gamma-ray attenuation was both measured experimentally and computed by means of a software. The measurements have been carried out for ores and mortar samples using 59.54, 662 and 1332 keV gamma photons. The theoretical values have

2020-01-16· Heavy weight concretes (HWCs) or heavy density concretes are commonly used for radiation shielding in nuclear plant to ensure protection against X-rays and Gamma rays. It can also be required in other structures where a large mass is needed. This experimental study was effected to design a HWC, which can be used in bentonite-bored piles concreting in order to remove as much as

The applications of radiation with X-ray appliances in medical and dental diagnosis are supervised by the sanitation department in both municipal and state levels, in accordance with rules established by the National Agency of Sanitary Supervision in Brazil ANVISA. Moreover, The Ministry of Labour and Employment also inspects the workplaces, with the view to control occupational exposures

The results showed that mortars prepared with barite and lead-laden recycled cathode ray tube funnel glass provided better shielding properties than mortars prepared with natural sand, natural crushed fine stone or crushed beverage glass. This is attributed to the use of dense aggregates being able to interact with X-ray radiation, thus reducing the depth of penetration. Due to the superior

The walls and doors, in an X-ray equipment room, must have their thickness accurately calculated as to assure protection of the public in general as well as the staff occupationally exposed to ionizing radiation. In practice, the dimensioning of the barite mortar and concrete used in building and plastering walls is determined by the principle of

This is attributed to the use of dense aggregates being able to interact with X-ray radiation, thus reducing the depth of penetration. Due to the superior shielding properties of the mortar containing barite, it can be used to replace traditional sand mortar for applications as rendering or plastering materials for the construction of medical diagnostic and CT scanner rooms.Department of Civil
