Gypsum - Vasuki Mines & Minerals

Gypsum (CaSO4.2H2O) is very similar to Anhydrite (CaSO4). The chemical difference is that gypsum contains two waters and anhydrite is without water. A massive fine-grained white or lightly tinted variety of gypsum, called alabaster, has been used for sculpture by many cultures. Gypsum also crystallizes as translucent crystals of selenite.

Bentonite Properties/ Specification - Arij Trading

Bentonite is an industrial rock which is occurred naturally, identified by the feature of water-absorbing and by the capacity for Base Exchange; both features are considerably greater than that of kaolin and plastic clays. In some bentonites, water absorption is supplemented by a significant increase in volume, size, and formation of gelatinous mass. Bentonite is […]

Effect Of Coir Fibres On The Compaction And Unconfined ...

This paper presents the effect of coir fibres on the compaction and unconfined compressive strength of a bentonite-lime-gypsum mixture. The coir fiber content varied from 0.5 to 2 %. The results indicated that the dry unit weight and the optimum moisture content of a bentonite - lime mix increased with the addition of gypsum. The unconfined compressive strength of the …

The end-time of primary swelling of bentonite + 8 % BENTONITE (AFTER TILAK ET AL., 2014) lime + 4 % gypsum + 1 % sisal fibres in duration of 40 days was 80 % less than that reached by bentonite. This accelerated reduction in Property Value swelling of bentonite brings new hope for the construction activities on such problematic areas.

Limestone – Algyr

Limestone. Limestone (CaCo3) is a sedimentary rock of chemical or biochemical origin that is composed mostly of calcium carbonate. This rock is mostly found in the form of clay limestone, sandy lime and dolomite. Pure lime is white, but the presence of impurities can change its color to some extent. If the impurities of limestone are magnesium ...
