Pre stressed concrete PSC is concrete in which internal stresses are developed in a predetermined manner such that the stresses induced due to external loading gets balanced with these internal stresses of concrete.

Knowing the ways and the extent to which problems can occur helps us implement the most cost-effective and long-lasting repairs possible. And most importantly, it helps us anticipate and avoid mistakes in our own work to create stronger, longer-lasting structures. PT beams and slabs have an inherent advantage over non-PT members when it comes to deflection. But it is still critical to check and correct for long-term deflection at the design stage. It is especially critical where drainage can be an issue in cases such as roofs, parking garages, and balconies, and with flat plates where long term deflections may affect window installation.

Slabs are one of the most basic components concerning the cost of the structure, because of the number of building materials utilized. It is of incentive to think about the current technologies available, meaning to make these slabs cost less or even improve its behaviour. Cobiax and post-tension slabs systems show up as an appropriate alternative. In light of this reason, this paper focuses on demonstrating the advantages and disadvantages of both Cobiax and post-tension systems. Nowadays, these systems are very popular all around the world. It is very necessary to have a wide understanding of the differences in cost and the construction duration between these two systems and have good knowledge about the advantages and disadvantages of both types. Firstly, the properties of these types of slabs have been reported and the advantages and disadvantages for both systems and then the cost and time has been compared, which are the most important factors for the owners.

Prestressed Concrete- Advantages and Disadvantages

In ordinary reinforced concrete , tensile stresses by steel alone and compressive stresses are taken up by concrete. Although steel takes up to the tensile stresses, the concrete at the tensile zone develops minute cracks. Th e load-carrying capacity of such concrete sections can be increased if steel and concrete both are stressed before the application of external loads. This is the concept of prestressed concrete. As per the ACI committee , prestressed concrete is that concrete in which internal stresses of suitable magnitude are introduced so that these stresses resulting from the external loadings can be counteracted to a desired degree. In RCC members, prestress induced is of compressive nature so that it balances the tensile stresses produced due to external load. It makes the whole section effective the concrete area in the tension zone also!

Pre-Stressed Concrete: Advantages, Disadvantages & Types of Tensioning

Thank you for sharing your thoughts and knowledge on this topic. This is really helpful and informative, as this gave me more insight to create more ideas and solutions for my plan. I would love to see more updates from you. Elcometer You there, this is a really good post here.

Prestressed Concrete is simply concrete that is stressed before concrete is poured in from work with the help of jack and tension embed in it. As we generally know that concrete is the mixture of three main ingredients which are cement fine mixture of clay, limestone, and small amount of gypsum ground up to the desired degree of fineness , sand only river sand or obtained through pit and aggregate Made form blasting and grinding from rocky soil and when we add water free from impurities in this mixture it creates concrete which we use for various civil work. Engineers come with the solution to introducing High strength steel bars into concrete members. Using this method they have overcome the problem of tensile stress which has allowed the engineer to achieve various possibilities such as reducing the size of member increasing span length etc.

Here are a few disadvantages of post tension slabs: 1. Since there are a number of tendons and wires spread inside the post tension slab, it can result in corrosion​.
