Feldspar and mica. Key minerals for fine aggregate quality ...

Dec 01, 1984  Research on the aggregate-concrete interaction has proved feldspar and mica to be key minerals for concrete quality. Feldspars are predominant minerals in most Norwegian aggregates. A relation has been found between the strength of cement mortars and the type and condition of the feldspars present. Especially, the degree of feldspar alteration (saussurite, sericite) appears to be a

Feldspar Cements A Color Guide to the Petrography of ...

Detrital feldspars most commonly undergo dissolution or alteration and replacement in subsurface settings, yet in many sandstones one also can find examples of authigenic feldspar cements. Such cements, in almost all cases, are either albite (the sodic end-member feldspar) or orthoclase (the K-spar end member)—see Chapter 2 for more details.

Feldspar - Wikipedia

Feldspars (K Al Si 3 O 8 – Na Al Si 3 O 8 – Ca Al 2 Si 2 O 8) are a group of rock-forming tectosilicate minerals that make up about 41% of the Earth's continental crust by weight.. Feldspars crystallize from magma as both intrusive and extrusive igneous rocks and are also present in many types of metamorphic rock. Rock formed almost entirely of calcic plagioclase feldspar is known as ...

Feldspar - Digitalfire

Geologists see feldspar as a mineral and classify feldspars as mainly as albite, microcline, orthoclase and anorthite. However, for use in glazes, we can view feldspars as 'warehouses of oxides' (e.g. because they supply K 2 O, Na 2 O, Al 2 O 3 and SiO 2 to the glaze melt). For this reason other materials like cornwall stone and nepheline ...
