Why is marble stronger than limestone?
Answers
Limestone is a rock that is formed when mud, sand, and shells are deposited in oceans and lakes and develop into a sedimentary rock. Since it is made up of fossilized particles, it is porous and is soluble in water. It is composed of silica, clay, silt, and sand. It also has many colors and may be crystalline, clastic, granular, or massive.
Although it is a heavy material and is not suitable for use in tall buildings, the great pyramid is made with limestone. It lasts long and is easy to cut and carve although it is more expensive than other materials. It has many uses such as:
Raw material for cement, mortar, and lime.
The manufacturing of cosmetics, medicines, glass, paper, plastic, tiles, and toothpaste.
Building material, artwork, pollution control, and soil neutralizer.
Source of calcium and water treatment.
Petroleum reservoir.
Marble, on the other hand, is a rock formed when limestone recrystallizes into marble during the mountain-building process. When rocks are formed, limestone is heated and squeezed which causes the grains to recrystallize.
It is metamorphic and is usually used as building material and in sculptures. Marble has many colors because of the mineral impurities in the limestone. Those that are used in sculptures are usually white. Light-colored marbles are used in various industries, and polished calcite, dolomite, and serpentine marble are used in construction.
