The use of prestressed concrete has_been_increasing sharply in recent years. This increased use of prestressed concrete is attributed to the significant improvements in the properties of the structure. Using prestressed concrete resulted in considerable enhancement of structure's resistance capacity. Also, prestressing concrete will improve the durability of structures by decreasing or eliminating the service cracks. We will tackle the concept of prestressed concrete. This course is one of the four courses I discussed earlier to assist in understanding the practical side of engineering. This aims to increase your knowledge of how prestressing improve the concrete's properties. Also, you will understand the benefits and types of prestressed concrete systems and the difference between them.
The second part of this course will discuss the following;
1. The component of a prestressed concrete system, the equipment used in performing prestressing of concrete, the procedure of constructing post-tensioning, and pre-tensioning systems.
2. It will discuss the process of tendon grouting and the benefits of grouting prestressing tendons. and,
3. We will discuss the jacking methods, jacking force, elongation of tendons, calibration of equipment, friction loss, and the prestressing force losses.
This course is not limited to the construction of prestressed concrete. It will not only_covers_ the problems associated with prestressing concrete but also to be oriented on how it will be prevented. To cite, what to do when you encounter issues in the grouting process of prestressing tendons and what will be the best way to avoid this.
Furthermore, we will discuss the external prestressing system and the circular prestressing of concrete.
This course will discuss mainly the practical side of prestressed concrete. Prestressed concrete is a big industry. The prestressed concrete can be used almost in every structure, such as buildings, bridges, liquid tanks, pressure pipes, and silos.
