What is concrete?

Concrete is a composite material used widely in the construction industry. Concrete is basically a mixture of cement, water, aggregates and admixture (sometimes). Cement is a fine gray powder that consists of oxidizes calcium, silicon and aluminum. The aggregate used is normally gravel, crushed stone or sand. Admixture is a solid or liquid substance that gives a certain characteristics of the concrete. The cement reacts with water chemically and binds the aggregates together through a process called hydration during hardening or curing of concrete. It means that water helps in the hardening of the concrete while the cement bind the aggregate and also react with water to form a solid mass.
Concrete is one of the most widely used construction material in the world. The reason for this is because concrete is strong, easy to make and can be molded into various shapes and sizes. Besides that, concrete is cheap, affordable and is readily mix.
Concrete also has its advantages. Concrete does not corrode, therefore concrete structures require less maintenance. Besides that, concrete has resistance to fire, therefore it is safer compare to the timber structure. Concrete has also resistance to cyclic loading.
In this report, we will introduce and illustrate on precast concrete, pre-stressed concrete, ready-mix concrete, reinforced concrete, terrazzo and Urbanite in details.
In this introduction, we will briefly introduce the sub-topic or types of concrete.
Reinforced concrete is stronger than basic concrete. Steel reinforcing bars known as rebar is incorporated in the concrete structure to act together in resisting the force. The steel reinforcing bars absorbs tensile and compression because plain conc...

In this essay, the author

  • Introduces and illustrates precast, pre-stressed, ready-mix, reinforced, terrazzo, and urbanite in this report.
  • Explains reinforced concrete is a type of concrete in which metal bars or wire is embedded to increase its tensile strength.
  • Explains that mixing, casting, and curing affect the final strength of concrete.
  • Explains that fibre is added to reinforced concrete to improve the characteristic of construction materials.
  • Explains pre-stressed concrete is a form of reinforced concrete that builds in compressive stresses during construction to oppose those found when in use.
  • Explains that the tendons are tensioned before the concrete is placed, and the tension force is released after it hardens. this method produces a strong bonding between the joints, protecting the tendon from rusting.
  • Explains post-tensioning is a method of strengthening concrete or other materials with high-strength steel strands (tendons).
  • Describes bridges, slabs in buildings, water tank, concrete pile, thin shell structure, offshore platform, nuclear power plant, repair and rehabilitations.
  • Explains that concrete is made up in industrial plants that contain storage facilities and equipment designed for the purpose of blending the raw material in desired proportion. the quality of concrete can be maintained only if the foundation is carefully administered.
  • Opines that special placing and formwork arrangements are required due to the large quantity of concrete available in short pan.
  • Explains the speed of construction can be very fast if rmc is used.
  • Explains precast concrete is a type of construction material which is cast and cured in factories, then transported to the construction site.
  • Explains residential (floors), infrastructure, prisons, medium and high rise buildings, hospitals, and commercial and industrial buildings.
  • Explains that precast concrete frames, walls, and floors are widely used in the building system.
  • Explains that precast concrete frame saves lots of time, not affected by weather or labour shortages, and improves build ability. it produces a high standard of workmanship in factory conditions.
  • Explains the advantages of precast walls, such as speed of construction, smooth surface finishing, acoustic insulation, and fire resistance.
  • Explains that precast floors can be classified according to their manufacture into totally and partially pre cast floors. the units are totally cast at the plant and the longitudinal joints are grouted.
  • Explains that it does not require an extensive footing like a real masonry wall and can be reset should it ever shift.
  • Explains that maintenance-free fences are maintenance free (no need to paint or periodically replace slats).
  • Describes bricks and blocks, floor and roofing elements, facade and wall elements and columns, infrastructure products.
  • Explains allen, e., iano, j. fundamentals of building construction: materials and methods. 5th edition.
  • Explains nawy, e. g., prestressed concrete: a fundamental approach. upper saddle river, n.j.
  • Explains marotta, theodore w., basic construction materials, upper saddle river, n.j.
  • Narrates prabhakara bhatt's prestressed concrete design to eurocodes. london; new york: spon press, 2011.
  • Explains that david a. fanella's reinforced concrete structures: analysis and design. new york: mcgraw-hill.
  • Describes levitt's precast concrete: materials, manufacture, properties and usage.
  • States that bachmann, h., & steinle, a. (2011). precast concrete structures.
  • Explains that concrete is a composite material used widely in the construction industry. concrete is strong, easy to make and can be molded into various shapes and sizes.
  • Explains that reinforced concrete is stronger than basic concrete. steel reinforcing bars are incorporated in the concrete structure to resist tensile and compression.
  • Explains that ready mixed concrete is a mixture of cement, sand, water and aggregate. too much water may cause the concrete weak or unworkable.
