Bentonite (/ ˈ b ɛ n. t ə ˌ n aɪ t /) is an absorbent swelling clay consisting mostly of montmorillonite.It usually forms from weathering of volcanic ash in seawater, which converts the volcanic glass present in the ash to clay minerals. Bentonite beds are white or pale blue or green in fresh exposures, turning to a cream color and then yellow, red, or brown as the exposure is weathered ...

In this study, ordinary Portland cement (OPC) and calcium-bentonite were used as the S/S for local sewage sludge from the Nanjing Wastewater Treatment Plant in China. Geotechnical properties of the solidified sludge were studied in terms of unconfined compressive strength (UCS) and durability after the wet and dry cycles.

The sodium form of bentonite clay is generally used for its swelling and sealing properties which mimic the function of cement. The calcium form of bentonite clay is used for its non-swelling, soil conditioning properties to improve water retention and increase nutrients in sandy soils.

Granular Sodium Bentonite Clay, when used appropriately, can be one of the most effective pond soil sealers available. There are two significantly different types of bentonite clay - Sodium Bentonite and Calcium Bentonite. Sodium bentonite clay is known as "high-swell" clay.

The Saudi calcium bentonite chips were crushed, ground, passed through a 90 μm sieve and then calcined in a prewarmed oven at 830 °C for 3 h, Fig. 1.

Bentonite continues to rank second in quantity only to barite as a mud additive, as shown in Fig. 11-2.14 In spite of the partial replacement of bentonite by polymers in some muds, about 1,160,000 short tons (1,050,000 tonnes) of swelling-type bentonite, with a well-site cost of roughly $120,000,000, was used in 1978.

Dry bentonite's specific gravity is around 2.4 - 2.8. Bentonites tend to break quickly into very small particles when in water dispersions. Wyoming Sodium bentonite provides 60-65% particles smaller than 0.1pm, around 90% particles are finer than 0.5 pm and around 97% will pass a 44 pm screen. Calcium bentonites are spread in water but ...

In this study, bentonite clay and lime were used as a partial replacement of Portland cement in mortar. The clay was calcined at 800, 850, 900 and 1000°C. Particle size distribution, chemical analysis, X-Ray diffraction, SEM analysis, and DSC analysis were completed as a high-level effort to characterize the chemical makeup of the bentonite clay. The Portland cement control mix had the ...

Furthermore, calcium bentonite (CB) is a natural pozzo-lanic material and contains more than 60% of SiO 2 [22]. According to the assessment of the strength activity in-dex (SAI) of concrete containing CB, the addition of up to 25% CB by weight of cement can provide a satisfactory SAI (more than 75%). Likewise, the compressive strength

The effects of bentonite on the pore structure and permeability of cement mortar were investigated in this paper.

Clay is a type of fine-grained natural soil material containing clay minerals. Clays develop plasticity when wet, due to a molecular film of water surrounding the clay particles, but become hard, brittle and non–plastic upon drying or firing. Most pure clay minerals are white or light-coloured, but natural clays show a variety of colours from impurities, such as a reddish or brownish colour ...
