https://civilsnapshot.com/disadvantages-reinforced-concrete Advantages of Reinforced Concrete Reinforced concrete has a high compressive strength compared to other building materials. Due to the provided reinforcement, reinforced concrete can also withstand a good amount tensile stress. Fibre reinforced concrete has a higher flexural strength than that of unreinforced concrete and concrete reinforced with welded wire fabric. Followings are the disadvantages of prestressed concrete: It requires high strength concrete and high tensile strength steel wires. Along with many advantages, reinforced concrete also poses some disadvantages also. Disadvantages of Concrete & Limitations. Better finishing of placed concrete. Disadvantages of Concrete are as follows: Concrete has a very low tensile strength and requires the use of reinforcing bars in concrete tensile zone. Fire and weather resistance of reinforced concrete is fair. ; Expensive formwork is required for casting and molding and to hold the concrete in place until it hardens sufficiently. The main steps of using reinforced concrete are mixing, casting, and curing. Reinforced concrete, as an economic building material, is very popular nowadays. But unlike conventional reinforcement – which strengthens in one or possibly two directions – Steel fibres reinforce iso tropically, greatly improving the concrete… One of the major disadvantages of reinforced concrete is the lack of tensile strength. Perhaps the greatest advantage of reinforced concrete construction is continuity. The durability of prestressed concrete is higher than the conventional reinforced concrete. 2. The tensile strength of reinforced concrete is about one-tenth of its compressive strength. Builders can make cast-in-place concrete even stronger by using steel reinforcement bars, or rebar, which is inserted in the form before the concrete is poured in. Disadvantages of Reinforced Concrete 1. Reinforced concrete has some characteristics that enhance its ability to resist earthquake forces, and others that are detrimental. Advantages of reinforced concrete 1. Though the concrete is strong in compression, it is very weak in tension. The prestressed concrete is much more usable in the construction of bridges, railway sleepers, and dams. It resists stresses are higher than normal RCC structures and is free from cracks. It requires a smaller amount of construction materials. It is widely used in many types building around the world. ADVANTAGES AND DISADVANTAGES OF REINFORCED CONCRETE. Therefore, usually, except on special occasions, the contribution of the tensile strength of concrete is not considered in the design. Advantages and Disadvantages of Reinforced Concrete Reinforced concrete is an amalgamation of conventional cement concrete along with reinforcements [steel bar]. Disadvantages of Prestressed Concrete. The dead load of the structure will be reduced by using prestressed concrete, and it indirectly reduces the usage of steel and project cost.
