Gypsum had the greatest interaction with bentonite as well but affected the rheological characteristics of bentonite in the opposite way to that observed with illite and Gypsum had the greatest interaction with bentonite as well but affected the rheological characteristics of bentonite in the opposite way to that observed with illite and The interaction of clay minerals with gypsum and its effects
Based on bentonite, two types of samples were prepared. Samples of the first type were obtained by mixing bentonite and gypsum, previously crushed in a mortar. Moreover, bentonite mixed with gypsum is a more economical means of production. Therefore, the investigated bentonite–gypsum materials have potential uses Materials Free Full-Text Investigation of Gamma-Ray
The results of bentonite-gypsum mixtures showed an increment in maximum dry unit weight and decrement in the optimum water content up to 4% inclusion of gypsum. A gradual reduction in the liquid Formation of micron-size pore can improve thermal insulation performance of gypsum. • Swelled bentonite can enhance moisture absorption/desorption of gypsum Preparation and hardened properties of lightweight gypsum plaster
In this study, we develop a new type of similar material to simulate strata separation. The skeleton of this material is made from river sand, while nanosized Abstract. A field experiment was conducted in a semi-arid region in northern China to evaluate the effects of bentonite soil amendment on field water-holding Effect of bentonite as a soil amendment on field water
this study, the basic material was bentonite, which was collected from Suez, Egypt. Here, it was crushed into smaller pieces and then ground into powder form. The second basic material was gypsum.In this study, carbide slag was used as the main material, bentonite was used as the Si/Al source, This separation is the main reason for the increase in loss rate, indicating that theFormation mechanism of carbide slag composite sustained
The investigation aims to check the effect of variation of gypsum and water content on the engineering properties of expansive soil by different experiments, namely, mini compaction test, Atterberg limit’s In this study, the basic material was bentonite, which was collected from Suez, Egypt. Here, it was crushed into smaller pieces and then ground into powder form. The second basic material was gypsum. The chemical compositions of bentonite and gypsum were analyzed using an Energy Dispersive X-ray (EDX), as shown in Table 1.Investigation of Gamma-Ray Shielding Properties of Bismuth
Due to the present industrial world, the risk of radioactivity is notably increasing. Thus, an appropriate shielding material needs to be designed to protect humans and the environment against radiation. In view of this, the present study aims to design new composites of the main matrix of bentonite–gypsum with a low-cost, abundant, With the development of the oil industry and the increasingly complex drilling environment, the performance of drilling fluids has to be constantly improved. In order to solve the problem of bentonite dispersion and hydration in a saline medium, a drilling fluid additive with good performance and acceptable cost was sought. The effects of several Gel Stability of Calcium Bentonite Suspension in Brine and Its
Gypsums played a vital role in the building materials, and gypsum whiskers were fiber-like crystals with small diameters and high aspect ratios, which performed lightweight, high strength, and green.The main variable is the proportion of bentonite (3%, 6%, 9%, 12%, 15%, 18% and 21% by weight of cement) in replacement mode while the amount of cementitious material, water to cementitiousPreparation and hardened properties of lightweight gypsum
Magnesium anodes installed underground are usually surrounded by a backfill material that typically consists of 75 % gypsum (CaSO42H2O), 20 % bentonite clay, and 5 % sodium sulfate (Na2SO4). The calcium sulfate, magnesium hydroxide test electrolyte simulates the long term environment around an anode installed in the gypsum-bentonite-sodiumGypsum deactivates the sodium bentonite for hydration and swelling by providing the Ca 2 + ions required to replace the Na + ions present in the sodium bentonite. The exchange of the Na + for bivalent cations is thermodynamically favourable, and complete replacement of Na + by Ca 2 + and Mg 2 + may happen ( Bradshaw et al., Interactions of clay minerals in copper–gold flotation: Part 2
The gypsum originating from PG fills up the void spaces left out after the rapid reaction of bentonite with lime, resulting in base exchange aggregation and flocculation . The presence of gypsum in lime-stabilized clay provides further Ca 2+ cations in addition to those provided by lime and [SO 4 ] 2− anions.Bentonite is a claystone formed by a complex mineralogical mixture, composed of montmorillonite, illite, and accessory minerals like quartz, cristobalite, feldspars, carbonates, and minor Minerals Free Full-Text Bentonite Powder XRD
Moreover, bentonite mixed with gypsum is a more economical means of production. Therefore, the investigated bentonite–gypsum materials have potential uses in applications such as In this study, zeolite composite with different compounds (minerals containing: gypsum, gypsum–bentonite, bentonite, calcite and pumice, and carboxylates containing: tartrate, citrate and oxalate) was investigated as an adsorbent of zinc ions. The oxalate-loaded zeolite composite was recognized as the best composite to remove zinc. Modification of Natural Zeolite by Carboxylate Compounds

Therefore, we designed a soil column leaching experiment with HA, gypsum and bentonite additions to test the following hypotheses: (1) Mixing HA and gypsum into costal saline soil can reduce the risk of N leaching; (2) The improvement effect of bentonite on saline soil can achieve the same effect as gypsum. 2.

The lower smectite contents of the materials tested in these studies (this study and [47,48]) are closer to the values measured for the Czech bentonite samples (e.g., Rokle-S65: 78 wt.% smectite), which produced a much smaller quantity of colloidal material (153 ± 19 ppm), possibly explaining why a gel was not observed in the tests using MX80The Black Steel slag (Ss) and phosphogypsum (PG) are industrial wastes produced in Morocco. In order to reduce these two wastes and to evaluate their pozzolanic reactivity in the presence of water, they were incorporated into bentonite (B) mixed with lime (L).
