5 Top Kind Of Stones Used In Building Construction

Landscape Pebbles and rocks are usually used in decorating homes and garden areas, whereas stones are being used for building construction. There are many types of stones naturally available such as marble, limestone, basalt, quartzite, gneiss, granite, and laterite or slate. Because of making heavy building structures, the stones should be hard, tough, and durable and bear heat and cold. They must be free from cracks, defects, and patches because they can reduce strength and affect durability. Stones from massive solid rocks are used for construction purposes.

1. Granite—for bridge piers

Granite is a heavy stone with durability and strength to bear tons of weight used to construct bridge piers, dams, stone columns, and ballast for railways, coarse aggregate in concrete, retaining walls, curbs, monumental utilization, and damp-proof course. The granite structure is crystalline, fine to coarse grain, and considered hard and durable as its strength comprises 100MPa to 250 MPa.

Granite has good resistance ability to frost and weathering, least porosity, low absorption value but poor resistance to fire. The finishing of this stone is well with grey color to pink and can be used as tabletops, walls, and cladding for columns.

2. Marble—for flooring

Marble is a well-known stone and works in the construction of flooring, steps, ornamental designing for columns, and varies strength quality from 70MPa to 75MPa. These stones are uniform in texture, take an excellent polish, least porous, and strong but easy to cut and carved into shapes. It is available in pink, white and other colors.

3. Quartzite—for slabs

This stone is used in building blocks, aggregate for concrete, and slabs because of its fine to coarse grain and mostly granular. It comes as branded and composed of feldspar and mica in small quantities with the strength 50MPa to 300MPa.White, gray, yellowish, and other colors are available.

4. Basalt—for road construction

It is known as traps and used for road construction, as aggregate in concrete production, river walls, rubble masonry works for bridge pier and dams. Its formation is medium to fine-grained and compact with a strength of 200MPa to 350Mpa, and its weight is between 18KN/m3 and 29KN/m3. It is difficult to dress in fine shapes but good resistance capacity, hard, strong, impervious to moisture, and color from dark grey to black.

5. Sandstone—for heavy structures

It helps build dams, masonry work, bridge pier, river walls, and other heavy structures with silica cement. It is available in many colors like yellow, red, dark grey, white, and grey as it's composed of feldspar and quartz. Strength ranges between 20MPa and 170MPa, and specific gravity varies from 1.85 to 2.7 make it suitable for building construction.

polished black pebbles landscaping, rocks, and stones are used in building, decorating, and constructing heavy structures. Some stones are combined with cement and other stones to increase the strength of the structure, like dams, piers, and other monuments.
