Following are the disadvantages of precast concrete: If not properly handled, the precast units may be damaged during transport. GRC has the compressive strength of 70mpa concrete which therefore makes it a perfect material for an exposed application and has a durability far better than reinforced concrete because it has no steel which is the general cause of concrete cancer. 5cm【デジコレクション】7f5. According to the concrete reinforcement theory, the concrete strength is increased with the increase in the fiber content. Disadvantages of Geopolymer Concrete While geopolymer concrete appears to be the super concrete to take the place of traditional Portland concrete, there are some disadvantages such as:. Other projects where precast concrete is suitable are large stadiums, halls, factories, awrehouses, airports and hangars. Concrete on its own has one major downfall and that is that it is extremely strong in compression but has little to no strength when there is tension. To produce textile reinforcements, continuous yarns or rovings are processed in a planar structure by a textile technique to produce an optimal alignment and arrangement of fibres in structural members (Figure 1).
Advantages / Disadvantages. Reinforced concrete can be cast in-situ concreted or can be precast concrete. Carbon fiber reinforced polymer (CFRP) may be used to retrofit existing reinforced concrete beams and provide the missing continuity needed to resist progressive collapse.
