Engineering properties of clay minerals 1. Montomonolite 2.kaolinite 3.illite 4.halloysite 5.allophone 6.gibbsite

Answer 1

1. Montomonolite

Montmorillonite is a very soft phyllosilicate group of minerals that form when they precipitate from water solution as microscopic crystals, known as clay.

2. kaolinite

Kaolinite is a layered silicate clay mineral which forms from the chemical weathering of feldspar or other aluminum silicate minerals. It is usually white, with occasionally a red color impurity due to iron oxide, or blue or brown from other minerals.

3.illite

Illite is a group of closely related non-expanding clay minerals. Illite is a secondary mineral precipitate, and an example of a phyllosilicate, or layered alumino-silicate.

4.halloysite

Halloysite is an aluminosilicate clay mineral with the empirical formula Al₂Si₂O₅(OH)₄. Its main constituents are oxygen, silicon, aluminium, and hydrogen. Halloysite typically forms by hydrothermal alteration of alumino-silicate minerals.

5.allophone

In phonology, an allophone (/ˈæləfoʊn/; from the Greek ἄλλος, állos, "other" and φωνή, phōnē, "voice, sound") is one of a set of multiple possible spoken sounds, or phones, or signs used to pronounce a single phoneme in a particular language.

6.gibbsite

Gibbsite, Al(OH)₃, is one of the mineral forms of aluminium hydroxide. It is often designated as γ-Al(OH)₃. It is also sometimes called hydrargillite. Gibbsite is an important ore of aluminium in that it is one of three main phases that make up the rock bauxite.
