Stones used in construction should be hard, durable, and free of cracks and other defects. Here are some stones used in construction: Marble A metamorphic rock that is naturally hard and compact, with a compressive strength of about 70 MPa. Marble is easily cut and carved into different shapes. Granite A commonly used stone for construction due to its hardness, strength, and durability. Granite has a compressive strength of 100–250 MPa.

Stones used in construction should be hard, durable, and free of cracks and other defects. Here are some stones used in construction:

Marble
A metamorphic rock that is naturally hard and compact, with a compressive strength of about 70 MPa. Marble is easily cut and carved into different shapes.

Granite
A commonly used stone for construction due to its hardness, strength, and durability. Granite has a compressive strength of 100–250 MPa.

Limestone
A commonly used stone in construction, often cut into blocks or slabs for stair treads. Limestone is strong and durable.

Sandstone
Used as a construction material since prehistoric times, sandstone is easy to work with and carve due to its grain structure, uniformity, and hardness.

Basalt
Used as a construction material due to its durability, hardness, and resistance to weathering. Basalt is used as crushed stone for road construction, railroad ballast, concrete aggregates, and building stones.

Quartzite
A metamorphic rock that is primarily used to cover walls as a decorative material. Quartzite is hard, textured, and strong.

Slate
A common stone used in construction, slate is sharp and can be cut into thin sheets for roofing. Slate is also used for grave markers
