What is structural concrete used for?
It is an important construction material used extensively in buildings, bridges, roads and dams. Its uses range from structural applications, to paviours, kerbs, pipes and drains.
Who developed the structural use of concrete?
600 BC – Rome: Although the Ancient Romans weren’t the first to create concrete, they were first to utilize this material widespread. By 200 BC, the Romans successfully implemented the use of concrete in the majority of their construction.
What is cp110?
CP 110 (1972) Code of Practice for Structural Use of Concrete: Part I—Design, Materials and Workmanship. Both destructive and non-destructive methods were used to determine the structure’s concrete strength. The number of reinforcements in each structural element was determined by exposing them.
How is concrete used in structures?
In the construction industry, concrete is most commonly used as the foundation for most structures. Concrete is used for many applications, including basic foundations, superstructures, wastewater treatment facilities, water treatment facilities, parking structures, floor construction, and exterior surfaces.
What is a concrete structure?
Concrete structures are usually inhomogeneous, containing a variety of materials (including cement, aggregates, pores, plaster, rebars, and steel fibres) with various thermal properties.
How is concrete used in construction?
How old is concrete construction?
Concrete is the most used building material and it has been used for many years. More than 5,000 years ago, Egyptians mixed mud and straw to form bricks and used gypsum and lime to make mortars.
Why concrete is used in construction?
Concrete Hardens at Ambient Temperature Concrete sets, hardens, gain its strength at regular room temperature or ambient temperature. This is because cement is a low-temperature bonded inorganic material. Thus concrete can be used irrespective of ambient weather conditions and optimized with admixtures if required.
Is concrete structural?
concrete, in construction, structural material consisting of a hard, chemically inert particulate substance, known as aggregate (usually sand and gravel), that is bonded together by cement and water.
Why is concrete used in construction?

What is the oldest concrete structure?
Alvord Lake Bridge
Five years later Ransome built the Alvord Lake Bridge in Golden Gate Park – the world’s first reinforced concrete bridge. The warehouse was demolished in 1930 but the bridge remains the world’s oldest surviving reinforced concrete structure.
What are the properties of concrete?
Hardened concrete has a number of properties, including:
- Mechanical strength, in particular compressive strength. The strength of normal concrete varies between 25 and 40 MPa.
- Porosity and density.
- Fire resistance.
- Thermal and acoustic insulation properties.
- Impact resistance.
When did CP110 come into use in the UK?
The recent history of Codes of Practice for structural concrete work in the UK has hardly been happy. For evidence of this, one need look no further than the sorry case of CP110 , which was introduced as a new Code in 1972 and withdrawn in 1985, while the predecessor it was meant to replace, CP114 , is still in use today.
Are there codes of practice for structural concrete in the UK?
The recent history of Codes of Practice for structural concrete work in conrcete UK has hardly been happy. Also according to a recent paper  the recommendations for designing shear reinforcement in flat slabs could result in insufficient links in some situations.
What are the different types of concrete codes?
1. CP110 The structural use of concrete, London, British Standards Institution, 1972. 2. CP114 The structural use of reinforced concrete in buildings, London, British Standards Institution, 1969. 3. BS8110 Structural use of concrete, London, British Standards Institution, 1985.
