General Glossary Questions
Below are some questions that we are asked on a regular basis.
Reinforced concrete is a composite material in which concrete’s relatively low tensile strength and ductility are counteracted by the inclusion of reinforcement having higher tensile strength and/or ductility. Reinforced concrete may also be permanently stressed (in compression), so as to improve the behaviour of the final structure under working loads.
Reinforced concrete is:
- An extra strong material especially in highly corrosive or stressed environments
- Highly tolerant to tensile strain
- Creates a good bond to the concrete, irrespective of pH and moisture
- Is thermally stable against changing temperatures or and is durable thermally hostile climates
Concrete has a proven record for strength, durability and cost effectiveness for a variety of applications so much so that engineers and architects are creating
Prestressed concrete is concrete in which internal stresses of such magnitude and distribution are introduced that the tensile stresses resulting from the service loads are counteracted to a desired degree; in reinforced concrete the pre-stress is commonly introduced by tensioning the tendons.
Post tensioning is the pre-stressing of a concrete member by tensioning the reinforcing tendons after the concrete has set
Precast concrete is a construction product produced by casting concrete in a reusable mould or “form” which is then cured in a controlled environment, transported to the construction site and lifted into place.
Fibre reinforced concrete (FRC) is concrete containing fibrous material which increases its structural integrity. It contains short discrete fibres that are uniformly distributed and randomly oriented.
A composite material, glass reinforced concrete (GRC) is a matrix of cement and fine aggregate reinforced with alkali resistant glass fibres which add flexural, tensile and impact strength to the finished product.
Concrete reinforcement is structural concrete with reinforcement having higher tensile strength and ductility to counteract concrete’s relatively low tensile strength and ductility.
Eurocodes are a set of harmonized technical rules developed by the European Committee for Standardisation for the structural design of construction works in the European Union.
Eurocode 2 and EC2 are both abbreviations for BS EN 1992, Eurocode 2: Design of concrete structures. There are four parts to BS EN 1992:
- BS EN 1992-1-1:2004 Design of concrete structures. General rules and rules for buildings
- BS EN 1992-1-2:2004 Design of concrete structures. General rules. Structural fire design
- BS EN 1992-2:2005 Design of concrete structures. Concrete bridges. Design and detailing rules
- BS EN 1992-3:2006 Design of concrete structures. Liquid retaining and containing structures
Civil engineering is a professional engineering discipline that deals with the design, construction and maintenance of the physical and naturally built environment, including works such as bridges, roads, canals, dams and buildings specifically built using concrete
Prestressed bridges are bridges built with prestressed concrete, overcoming concrete’s natural weakness in tension. Prestressed bridges have a longer span than with ordinary reinforced concrete.
