Abstract. Cements, in a general sense, are adhesive materials which are capable of bonding together fragments or particles of solid matter into a compact whole. This definition covers a wide variety of materials, but for engineering purposes it is generally restricted to ‘calcareous cements’, i.e. those which contain compounds of lime as

The chemical composition of sediments and sedimentary rocks is extremely diverse, reflecting the variability of the mineralogical composition. Sediments may be classified according to the origin of the minerals composing the bulk sediment. End members are designated as terrigenous (siliciclastic), biogenic, and metalliferous. Terrigenous
characterized by a low K as well as high Al and Fe. The shales are seen enriched with Ti. The mineralogical analysis suggests the composition of the shales, predominated by main clay minerals aolinite and as k chlorite in addition to variable ratio of montmorillonite, while the non clay minerals include q- uartz, calcite and siderite.
So, chemical and mineralogical investigations were carried out on these inorganic materials. The glass phase which was formed by quenching is difficult to characterize by X-ray analysis by every CCP, and discussed only how percentage of glass phases, without not …
The characterization and comparison of sludge ashes at various ashing temperatures were carried out to study the relationship between the ashing fusibility, physicochemical properties, and thermogravimetric characteristics. The low temperature ashes were black gray and had the characteristic of the coexistence of irregular and rounded particles, which contained a certain proportion of residual
paper is to review the chemical, mineralogical, and physical properties of the martian dust and soil. Chemical Properties: A host of lander and orbital missions have characterize the chemical composition of dust and soil.

Igneous rock - Igneous rock - Mineralogical components: The major mineralogical components of igneous rocks can be divided into two groups: felsic (from feldspar and silica) and mafic (from magnesium and ferrous iron). The felsic minerals include quartz, tridymite, cristobalite, feldspars (plagioclase and alkali feldspar), feldspathoids (nepheline and leucite), muscovite, and corundum.
Initially those chemical components which characterize the composition of minerals in the assemblages under consideration must be identified. In addition, the reaction relationships among components must be systematically characterized. or write Mineralogical Society of America, 3635 Concorde Pkwy Ste 500, Chantilly, VA 20151-1110 United

Mineral - Mineral - Classification of minerals: Since the middle of the 19th century, minerals have been classified on the basis of their chemical composition. Under this scheme, they are divided into classes according to their dominant anion or anionic group (e.g., halides, oxides, and sulfides). Several reasons justify use of this criterion as the distinguishing factor at the highest level
