1. introduction to concrete chapter 1

  1. 1. Chapter-1Chapter-1 Introduction of Concrete
  2. 2. Aims and ObjectivesAims and Objectives Understanding concrete as a structural material, its application and appreciation of its complexity, performance and reliability.
  3. 3. Aims and ObjectivesAims and Objectives Able to define properties of constituent materials – origins and uses. Understand the concepts of hydraulicity. Able to define types of Portland cement, production methods and application. Know the properties of materials for concrete, and the test methods. Able to carry out mix design, mix process and tests for workability. Understand the importance of curing. Able to carry out strength testing including non- destructive testing.

  9. 9. Concrete FutureConcrete Future It is estimated that by 2025 about 66 per cent of the world population will live in urban areas on 7 per cent of the land. That means that urbanization will be on a small portion of land. This will need taller buildings and use of high strength concrete. Also good infrastructure such as water supply, drainage, better quality roads (concrete should be the obvious choice) etc. will be required. This will boost the construction industry and that will boost cement production.
  10. 10. Concrete FutureConcrete Future The pace of construction will be fast which will require high strength cement. Concrete will have to be durable and of good quality, therefore, with high strength cements, the materials like silica fume, processed fly ash and ground granulated blast furnace slag will be used. Cement with chemical and mineral admixtures will be used to produce concrete of desired strength, workability and durability.
  11. 11. Facts and FiguresFacts and Figures Concrete’s versatility, durability, and economy have made it the world’s most used construction material. The U.S. uses about 340 million cubic yards (260 million cubic meters) of ready-mixed concrete each year. It is used in highways, streets, parking lots, parking garages, bridges, high-rise buildings, dams, homes, floors, sidewalks, driveways, and numerous other applications.
