Composition of cement Introduction Portland cement gets its strength from chemical reactions between the cement and water The process is known as hydrationThis is a complex process that is best understood by first understanding the chemical composition of cement
Geologists often describe bentonite as a clay mineral containing Montmorillonite, which poses a rather curious problem, as Montmorillonite is a name of a particular clay that was discovered in Montmorillon, France, named by Mauduyt in 1847
The clay fraction, because of its high surface area, is the most active part of the soil controlling many of the chemical and physical properties of the soil It is the seat of soil fertility The sand and silt fractions i influence mainly the physical properties of the soil
Montmorillonite Comments: Authigenic smectite (montmorillonite) overgrown on pore spaces and authigenicly-overgrown quartz grains in a sandstone SEM image of a core sample
1 SUMMARY 11 Identity, physical and chemical properties, and analytical methods Bentonite is a rock formed of highly colloidal and plastic clays composed mainly of montmorillonite, a clay mineral of the smectite group, and is produced by in situ devitrification of volcanic ash In addition to montmorillonite, bentonite may contain feldspar, cristobalite, and crystalline quartz
Kaolinite (/ ˈ k eɪ ə l ɪ n aɪ t /) is a clay mineral, part of the group of industrial minerals, with the chemical composition Al 2 Si 2 O 5 4 It is a layered silicate mineral , with one tetrahedral sheet of silica (SiO 4 ) linked through oxygen atoms to one octahedral sheet of alumina (AlO 6 ) octahedra

The physical and chemical properties of a particular clay mineral are dependent on its structure and composition A useful classification of the clay minerals ( Table 1 ) was proposed and used by Grim in his book (1968), which is a basis for outlining the nomenclature and differences between the various clay minerals
“Clay minerals are hydrous aluminium phyllosilicates, sometimes with variable amounts of iron, magnesium, alkali metals, alkaline earths and other cations Clays have structures similar to the micas and therefore form flat hexagonal sheets , These tetrahedral sheets have the chemical composition ,

Clay minerals are layer silicates that are formed usually as products of chemical weathering of other silicate minerals at the earth's surface They are found most often in shales, the most common type of sedimentary rock In cool, dry, or temperate climates, clay minerals are fairly stable and are an important component of soil
These minerals are similar in chemical and structural composition to the primary minerals that originate from the Earth's crust; however, transformations in the , above forms the template for the silicate clay minerals However, the composition varies frequently due to substitution of ions within the mineral structure , Clay Minerals 1:1 .
Clay mineral: Clay mineral, any of a group of important hydrous aluminum silicates with a layer (sheetlike) structure and very small particle size They may contain significant amounts of iron, alkali metals, or alkaline earths The term clay is generally applied to (1) a natural material with plastic
