From prehistoric times there have been examples of graves covered with a stone slab, in its natural state or carved. This use of slabs as tombstone has extended the concept of natural slab to the tombstone variant: flat, thin and polished. An instance is the slab in the tomb of King Pere el Gran of Aragon, which weighs 900 kg. [8]
A metate (or mealing stone) is a type or variety of quern, a ground stone tool used for processing grain and seeds. In traditional Mesoamerican cultures, metates are typically used by women who would grind nixtamalized maize and other organic materials during food preparation (e.g., making tortillas ).
Slate is a fine-grained, metamorphic rock that shows no obvious compositional layering but can easily be split into thin slabs and plates. [2] [3] It is usually formed by low-grade regional metamorphism of mudrock.
PT stone has been used in both vertical columns (posts), and in horizontal beams (lintels). It has also been used in more unusual engineering applications: arch stabilization, flexible foot bridges, and cantilevered sculptures. Tensioned stone has a close affiliation with massive precut stone as two central techniques of modern stonemasonry.
Slab pull force, the tectonic plate force due to subduction; Slab suction, one of the major plate tectonic driving forces; Slab window, a gap that forms in a subducted oceanic plate; Slab (fossil) and counter slab, the two counterparts of a fossil impression; Slab hut, a kind of dwelling made from slabs of split or sawn timber; Slab of beer, a ...
Bonded terrazzo is applied over a sand-cement mortar underbed which sits on top of a concrete slab. The sand-cement layer allows for variations in the finished concrete slab that it sits on. Monolithic terrazzo is applied directly over an extremely flat and high quality concrete sub-floor. Thin-set terrazzo does not require a concrete sub-floor.
Stone slab in east-central California used to grind acorns. In archaeology, a grinding slab is a ground stone artifact generally used to grind plant materials into usable size, though some slabs were used to shape other ground stone artifacts. [1] Some grinding stones are portable; others are not and, in fact, may be part of a stone outcropping.
Close-up of granolithic sidewalk. Granolithic screed, also known as granolithic paving [1] and granolithic concrete, [2] is a type of construction material composed of cement and fine aggregate such as granite or other hard-wearing rock. [3]
