A concrete spacer with a plastic clip in use Concrete spacers in a precast element Diaphragm wall block on rebar for a Diaphragm wall A rebar spacer is a short, rod-like device used to secure reinforcing steel bars, or rebar , within cast assemblies for reinforced concrete structures.
The rebars are placed by steel fixers ("rodbusters" or concrete reinforcing iron workers), with bar supports and concrete or plastic rebar spacers separating the rebar from the concrete formwork to establish concrete cover and ensure that proper embedment is achieved.
Steel casing pipe is often specified as ASTM A-252 which is a structural grade material that does not require hydrostatic testing and the inspection requirements are not stringent and it usually costs less than other grades such as A-53, [2] A-139 or API 5L. Used natural gas line pipe is also used as casing on many projects because it is often ...
In general, a spacer is a solid material used to separate two parts in an assembly. Spacers can vary in size from microns to centimeters. They can be made of metal, plastic, glass, and other materials. Shapes include flat sheet, cylindrical and spherical. Two sizes of metal standoffs and one plastic standoff.
Polymer concrete, also known as Epoxy Granite, is a type of concrete that uses a polymer to replace lime -type cements as a binder. In some cases the polymer is used in addition to Portland cement to form Polymer Cement Concrete (PCC) or Polymer Modified Concrete (PMC). [1] Polymers in concrete have been overseen by Committee 548 of the ...
Expansion joint on a bridge. A expansion joint, or movement joint, is an assembly designed to hold parts together while safely absorbing temperature-induced expansion and contraction of building materials. They are commonly found between sections of buildings, bridges, sidewalks, railway tracks, piping systems, ships, and other structures.
Filler materials are particles added to resin or binders (plastics, composites, concrete) that can improve specific properties, make the product cheaper, or a mixture of both. [1] The two largest segments for filler material use is elastomers and plastics. [2] Worldwide, more than 53 million tons of fillers (with a total sum of approximately US ...
Poly (methyl methacrylate) (PMMA) is the synthetic polymer derived from methyl methacrylate. It is used as an engineering plastic, and it is a transparent thermoplastic. PMMA is also known as acrylic, acrylic glass, as well as by the trade names and brands Crylux, Hesalite, Plexiglas, Acrylite, Lucite, and Perspex, among several others (see below).
