Sandstone is a very hard, resistant, compact, and fine-grained equi-granular homogeneous rock composed primarily of silica. It is highly resistant to acids and thermal impacts. Ancient Egyptian temples and structures used sandstone in massive towers, pillars that experience tension, and beams that experience bending.
