Advantages of Prestressed Concrete 1.Durability As this technique eliminates weakness of concrete in tension, such members remain free from cracks; hence can resist the effects of impact, shock, and reversal of stresses more efficiently than R.C.C. The disadvantages of concrete are: 1. Moreover, these aggregates are not robust, which leads to lowering concrete strength. Different Special types of concrete : Light Weight Concrete Plum. Not only will properly adding a concrete sealer slow down aging and weathering, it can also protect against staining, and add aesthetic visual appeal which can only bring more value to your property. Damaged plaster must be cut and scraped out without damaging the intact wall material. It can be used to support large spans. Reinforced concrete members require additional shear reinforcements to resist shear forces. 021 69113328. Zippe Industrieanlagen received an order for a new batch plant in Ayutthaya from Osotspa (Siam Glass) in 2017. Disadvantages of Prestressed concrete It is economical for large-span structures only. to feed, water and feed additives, transmission and storage stirred their workflow shown in Figure 1. , the mixer control system power, into the human - machine dialogue operation interface, system initialization process, including recipe . More modest areas can be utilized for longer span by reducing the segment of members. 2. Bolt, Refined Rolled Thread
