Bentonite is also used as a binding agent in the production of iron ore pellets, as well as in the production of cement and concrete. It can improve the strength and durability of these materials. In the cosmetic industry, bentonite is often used in face masks and other skincare products due to its ability to absorb oils and impurities from the ...

The LGPs in this study were designed using a volumetric method. Table 2 describes the mix parameters of the LGPs. Fresh LGP slurry consisted of gypsum paste and bentonite slurry. Prior to the experiment, pre-saturated bentonite slurry (bentonite: water = 1:5, 1:10, 1:15, 1:20) was prepared by mixing tap water and bentonite for 1 h …

This review focuses on the appropriateness of bentonite clay as a binding material in concrete production. The attention of this review is to discuss the physical …

The two main types of conventional backfill materials are bentonite- and cement-based materials. Previous studies (Allan, 2000, 1997, 1996; ... and the continued compaction of the specimen resulted in solid–liquid separation. The thermal conductivity of the backfill material with the same dry density showed a trend of increasing first and ...

2.1 Materials 2.1.1 Bentonite. Bentonite used in this study was provided by China Baowu WISCO Group Co., Ltd. (Wuhan, China). The chemical compositions and physical properties of bentonite are shown in Tables 1 and 2, respectively.The main ingredients of the bentonite are 52.34 wt.% SiO 2 and 18.95 wt.% Al 2 O 3, and the …

Lightweight gypsum plasters (LGPs)were successfully prepared by adding pre-swelled bentonite to gypsum paste. As the content of bentonite slurry increased from 0% to 40%, the excessive water in ...

Based on the traditional cement-gypsum bonded material, bentonite was added to regulate the water sensitivity of the material. Using the orthogonal experiment method, 25 schemes of the material ...

The results of the ABM tests are particularly valuable for the verification of gypsum dissolution and precipitation reactions and their modelling because rather …

Wang et al. [1] used river sand, nanometer-sized calcium carbonate, gypsum, bentonite, and emulsified wax to prepare similar materials for solid-fluid coupling model testing and found that the ...

Bentonite. Gypsum. Trona. Phosphate. Aggregate / Construction. Decorative Stone. Bentonite includes any natural material dominantly composed of clay minerals in the smectite group. Wyoming bentonite consists of hydrous silicate of alumina, commonly referred to as montmorillonite clay. Also known as sodium bentonite, Wyoming …

This paper uses similar theory to configure a kind of expansive soil to carry out indoor model experiments. By selecting sand, gypsum, and bentonite to artificially configure a mixture with similar expansion and contraction characteristics, the expansion characteristics of expansive soil are studied under water immersion conditions.

Comparison of this study, which uses a bentonite-gypsum matrix and Bi2O3 NPs (filler), with El-Sharkawy et al. [31], where nanoscale Bi2O3 was used as filler in a bentonite matrix, at the same ...
