It is composed of quartz and feldspar and found in different colors such as white, grey, red, buff, brown, yellow, and dark gray. The compressive strength ranges between 20MPa and 170MPa, and specify gravity varies from 1.85 to 2.7. It should be known that weathering sandstone makes it unsuitable for building construction.
Plagioclase Feldspar | Physical-Optical Properties,
This decrease is partly because quartz is more physically and chemically durable than feldspar and persists in greater relative quantities downstream in eroded sediments. Plagioclase Uses Area. Plagioclase minerals are important constituents of some building stone and crushed stone such as granite and trap rock.

What Is Granite?
Jan 13, 2019· Stone dealers have a third, much-different set of criteria for granite. Granite is a strong stone because its mineral grains have grown tightly together during a very slow cooling period. Additionally, the quartz and feldspar that compose it are harder than steel. This makes granite desirable for buildings and ornamental purposes, such as,

Decomposed granite - Wikipedia
Decomposed granite is rock of granitic origin that has weathered to the point that it readily fractures into smaller pieces of weak rock. Further weathering produces rock that easily crumbles into mixtures of gravel-sized particles, sand, and silt-sized particles with some clay.Eventually, the gravel may break down to produce a mixture of silica sand, silt particles, and clay.

Also called “arkosic sandstone” and “feldspathic sandstone.” Arris A slight, although measurable, chamfer where two surfaces meet Artificial Stone A manmade product attempting to
Quartz – Unique Stone Concepts
Quartz Quartz is a man-made engineered stone surface formed by combining 90% ground quartz (a natural hard mineral) with 8-10% resins, polymers, and pigments. This forms a very hard granite-like surface. How it looks depends on how the quartz is ground: coarsely-ground quartz produces a flecked appearance while finely-ground quartz produces a smooth look.
What is clay? — Science Learning Hub
Clay is a soft, loose, earthy material containing particles with a grain size of less than 4 micrometres (μm). It forms as a result of the weathering and erosion of rocks containing the mineral group feldspar (known as the ‘mother of clay’) over vast spans of time.
Slate - Wikipedia
Slate is a fine-grained, foliated, homogeneous metamorphic rock derived from an original shale-type sedimentary rock composed of clay or volcanic ash through low-grade regional metamorphism.It is the finest grained foliated metamorphic rock. Foliation may not correspond to the original sedimentary layering, but instead is in planes perpendicular to the direction of
