The basic soil, along with calcium carbonate from the caliche, can prevent plants from getting enough nutrients, especially iron. An iron deficiency makes the youngest leaves turn yellow. Soil saturation above the caliche bed can make the condition worse. [22] Its hardness can also make digging for projects such as canals more difficult.

Those advantages include: (1) many types of stone are stronger than concrete in compression; (2) stone uses much less energy to produce, and hence its production emits less carbon dioxide than either brick or concrete, and (3) stone is widely considered aesthetically pleasing, while concrete is often painted or clad.
Monument of laterite brickstones at Angadipuram, Kerala, India, which commemorates where laterite was first described and discussed by Buchanan-Hamilton in 1807. Laterite is a soil type rich in iron and aluminium and is commonly considered to have formed in hot and wet tropical areas. Nearly all laterites are of rusty-red coloration, because of ...
Pumice is widely used to make lightweight concrete and insulative low-density cinder blocks. The air-filled vesicles in this porous rock serve as a good insulator. [ 18 ] A fine-grained version of pumice called pozzolan is used as an additive in cement and is mixed with lime to form a light-weight, smooth, plaster-like concrete.
Cobblestone is a natural building material based on cobble-sized stones, and is used for pavement roads, streets, and buildings. Setts, also called Belgian blocks, are often referred to as "cobbles", [1] although a sett is distinct from a cobblestone by being quarried and shaped into a regular form, while cobblestones are naturally occurring forms less uniform in size.
Roman concrete, like any concrete, consists of an aggregate and hydraulic mortar, a binder mixed with water that hardens over time. The composition of the aggregate varied, and included pieces of rock, ceramic tile, lime clasts, and brick rubble from the remains of previously demolished buildings. In Rome, readily available tuff was often used ...
