Concrete as a Building Material: Issues and Practiced Solutions Concrete is a construction material which consists of a binding material, a filler material and water. The commonly used binding material is cement and the filler material consists of aggregates coarse as well as fine aggregates.
Water is essential component of concrete because it gives the concrete the required fluidity which helps in pouring concrete in the various forms of constructional shapes and for fabricating structural members of various sizes, more importantly water is required for the hydration of cement. The cement and thus the concrete gets the desired strength after the process of hydration in which the cement react chemically with water and physically with the aggregates to form a strong and homogeneous stone-like mass of concrete. Concrete has a very high compressive strength due to the presence of crushed stones and aggregates of high strength; however its brittle nature makes it a very weak material in tension. This is the reason concrete has to be reinforced by using other materials which are strong in tension in situations where the structural members is also subjected to tension in addition to compression. The most widely practiced reinforcement is done by steel bars embedded in concrete for resisting tension. Sometimes it is also reinforced with bricks and reinforcement of concrete with fibers is the most modern method of reinforcement. ...
