However, shotcrete may also sometimes be used to distinguish wet-mix from the dry-mix method. The term shotcrete was first defined by the American Railway Engineers Association (AREA) in the early 1930s. [6] By 1951, shotcrete had become the official generic name of the sprayed concrete process—whether it utilizes the wet or dry process. [6]
Conco provides concrete services for the Western U.S. that include professional concrete building design, formwork, reinforcement, shotcrete, pumping, and place and finish. In addition, Conco is one of the largest independent reinforcing steel and post tension contractors on the West Coast, with state-of-the-art rebar fabrication facilities in ...
Traditional rebars are generally used to improve the tensile strength of the concrete in a particular direction, whereas steel fibers are useful for multidirectional reinforcement. This is one of the reasons why steel fiber reinforced (shotcrete form) concrete successfully replaced weldmesh in lining tunnels. Less labour is required.
Bars installed using drilling techniques are usually fully grouted and installed at a slight downward inclination with bars installed at regularly spaced points across the slope face. A rigid facing (often pneumatically applied concrete, otherwise known as shotcrete) or isolated soil nail head plates may be used at the surface. [1]
Banthia has developed a number of novel methodologies for fibers use in concrete and shotcrete reinforcement, developed a family of fibres for reinforcing Portland cement-based materials, pioneered research in microfiber-reinforced cement composites for civil applications, demonstrated use of fiber-reinforced polymers (FRPs) in new construction ...
The Operative Plasterers' and Cement Masons' International Association of the United States and Canada (OPCMIA) is a trade union of plasterers and cement masons in the construction industry in the United States and Canada. Members of the union finish interior walls and ceilings of buildings and apply plaster on masonry, metal, and wire lath or ...
Stamped concrete is an architectural concrete that has a superior surface finish. After a concrete floor has been laid, floor hardeners (can be pigmented) are impregnated on the surface and a mold that may be textured to replicate a stone / brick or even wood is stamped on to give an attractive textured surface finish.
Today The Concrete Society is an independent concrete advisory company, providing information to industry clients, architects, engineers, specifiers, suppliers, contractors and users of concrete. [2] The society is an individual membership body, without trade affiliations, which exists to provide information to exchange information and ...
