types of stone for building houses: types of Building Stones

types of stone for building houses

types of stone for building houses; The following Eight types of stones are the sum of commonly used stones in civil engineering works.

  1. Basalt and trap
  2. Granite
  3. Sandstone
  4. Slate
  5. Laterite
  6. Marble
  7. Gneiss
  8. Quartzite

Basalt and Trap

  • Basalt and Trap are the structure is average to fine-grained and compact. Their shade differs from dark gray to black. breakage and joints are common.
  • Their weight differs from 18kN/m3 to 29kN/m3. The compressive strength differs from 200 to 350 N/milimeters2. These are igneous rocks. They are worn as road metals, aggregates for concrete.
  • They are also worn for rubble masonry works for bridge pillars, river walls, and dams. They are worn as pavement.

Granite

  • Granites are as well igneous rocks. The color differs from light gray to pink. The structure is transparent, fine to coarse-grained. They lay hold of polish well.
  •  They are firm durable. Specific gravity is from 2.6 – 2.7 and compressive strength is 100 – 250 N/mm2. They are worn primarily for bridge pillars, river walls, and dams.
  •  They are worn as kerns and Architecture. The use of granite for huge and institutional buildings as usual.
  •  Polished granites are worn as tabletops, cladding for columns, and constructed walls. They are worn as coarse aggregates in concrete.

Sandstone

  • These are sedimentary rocks and therefore stratified. They comprise quartz and feldspar. They are established in several colors such as white, grey, red, buff, brown, yellow, and even dark gray.
  • The specific gravity differs from 1.85 kg m-3 to 2.7 kg m-3 and compressive strength differs from 20 to 170 N/mm2. Its porosity differs from 5 to 25 percent. Weathering of rocks provides it unsuitable as building stone.
  •  It is advantageous to worn sandstones with silica cement for heavy structures, if required. They are worn for masonry work, dams, bridge pillars, and river walls.

Slate

  • These are metamorphic rocks (slate rock). They are collected of quartz, mica, and clay minerals. The structure is fine-grained. They cleave along the planes of original bed linen easily.
  • The color differs from dark gray, greenish-gray, purple-gray to dark black. The peculiar gravity is 2.6 – 2.7. Compressive strength differs from 100 to 200 N/mm2. They are worn as roofing tiles, slabs, pavements, etc.

Laterite

  • It is a metamorphic rock (Laterite). It is having a penetrable and sponges structure. It accommodates a high percentage (%) of iron oxide ( Fe2O3). Its cast may be brownish, red, yellow, brown, and grey.
  • Its specific gravity is 1.85 kg m-3 and compressive strength differs from 1.9 to 2.3 N/mm2. It can be easily dissension in blocks.
  •  With seasoning, it procures strength. When worn as building stone, its outer area should be plastered.

Marble

  • This is a metamorphic rock (Marble). It can rest hold of a good polish. It is accessible in different pleasing shades like white and pink. Its specific gravity is 2.65 and compressive strength is 70 to 75 N/ mm2.
  •  It is worn for facing and decorative works. It is worn for columns, flooring, steps, etc.

Gneiss

  • It is a metamorphic rock (Gneiss). It possesses fine to coarse grains. substitute dark and white bands are common. Light grey, pink, purple, greenish-gray, and dark grey shade varieties are accessible.
  • These stones are not favored because of the deleterious ingredient present in them. They may be worn in minor constructions. However hard differences may be worn for buildings.
  • The specific gravity differs from 2.5 to 3.0 and crushing strength differs from 50 to 200 N/mm2.

Quartzite

  • The Quartzites are metamorphic rocks. The structure is great to coarse-grained and frequently granular and branded. They are available in contrasting colors like white, gray, yellowish. Quartz is the primary constituent with feldspar and mica in mini quantities.
  •  The specific gravity differs from 2.55 to 2.65. Crushing strength differs from 50 to 300 N/mm2. They are worn as building blocks and slabs. They are also worn as aggregates for concrete.
