Vibro stone columns or aggregate piers are an array of crushed stone pillars placed with a vibrating tool into the soil below a proposed structure. This method of ground improvement is also called vibro replacement. Such techniques increase the load bearing capacity and drainage of the soil while reducing settlement and liquefaction potential ...
A slurry wall is a barrier built under ground using a mix of bentonite and water to prevent the flow of groundwater. A trench that would collapse due to the hydraulic pressure in the surrounding soil does not collapse as the slurry balances the hydraulic pressure.
Tensioned stone can consist of a single block of stone, though drill limitations and other considerations mean it is typically an assembly of multiple blocks with grout between pieces. [1] Tensioned stone has been used in both vertical columns (posts), and in horizontal beams (lintels).
Block-making machines may form blocks that have interlocking shapes to reduce the requirement for mortar. The block may have holes or grooves so rods such as bamboo can be inserted to improve earthquake resistance. [36] Suitable earth must be used, with enough clay to hold the block together and resist erosion, but not too much expansive clay. [37]
Enables reuse of rough plum stones from traditional stone masonry. The first documented architectural use of precut cyclopean concrete blocks was in a social housing project on Mallorca in the early 2020s. Tensioned stone. Stone beams and columns can be strengthened by drilling a duct that is threaded with a tension cable.
Bretonstone, also known as vibro-compression under vacuum, is a formerly-patented technology [2] [3] invented in the early-1970s [citation needed] by Breton S.p.A. [4]Nowadays most manufacturers of engineered stone use similar technology, typically involving quartz and a resin binder combined under vacuum, and compressed under heat into a desired form such as a countertop slab.
