Plant fibers are a promising area but they are subjected to degradation in the alkaline environment and elevated temperatures during cement hydration. [3] [4] In international literature, FRCMs are also called textile-reinforced concrete (TRC), textile reinforced mortars (TRM), fabric-reinforced mortar (FRM), or inorganic matrix-grid composites ...
The following are several international standards for fiber-reinforced concrete: [35] BS EN 14889-1:2006 – Fibres for Concrete. Steel Fibres. Definitions, specifications & conformity; BS EN 14845-1:2007 – Test methods for fibres in concrete; ASTM A820-16 – Standard Specification for Fiber-Reinforced Concrete (superseded)
A silt fence on a construction site.. Geotextiles and related products have many applications and currently support many civil engineering applications including roads, airfields, railroads, embankments, retaining structures, reservoirs, canals, dams, bank protection, coastal engineering and construction site silt fences or to form a geotextile tube.
Concrete roofing is composed of concrete reinforced with fibers of some sort. Structural concrete can also be used for flat roof constructions. There are three main categories, precast/prestressed, cast-in-place and shell. There are many types of precast/prestressed concrete roofing. The following are the most common types. [8]
However, most HPFRCCs include at least the following ingredients: fine aggregates, a superplasticizer, polymeric or metallic fibers, cement, and water. Thus the principal difference between HPFRCC and typical concrete composition lies in HPFRCCs' lack of coarse aggregates. Typically, a fine aggregate such as silica sand is used in HPFRCCs.
The first artificial fibre reinforced plastic was a combination of fiber glass and bakelite, performed in 1935 by Al Simison and Arthur D Little in Owens Corning Company [15] One of the most common and familiar composite is fibreglass , in which small glass fibre are embedded within a polymeric material (normally an epoxy or polyester).

Concrete reinforced with fibers (which are usually steel, glass, plastic fibers) or cellulose polymer fiber is less expensive than hand-tied rebar. [citation needed] The shape, dimension, and length of the fiber are important. A thin and short fiber, for example short, hair-shaped glass fiber, is only effective during the first hours after ...
