There are five types of cracks that may develop in prestressed concrete beams with openings. These crack types and method of controlling those cracks will be explained in this article. Various kinds of cracks in prestressed concrete beams with openings ...
Mix Design of High Strength Concrete -Methods, Procedure and Example
Mix design of high strength concrete is influenced by properties of cement, sand aggregates & water-cement ratio have compressive strength above 40 MPa. To achieve high strength, it is necessary to use lowest possible water-cement ratio, which invariably affects the ...
Prestressed Concrete Pipes – Types, Uses and Manufacture
Prestressed concrete pipes are widely used around the world and slowly replacing RCC pipes and steel pipes. They have more strength than RCC pipes and economical compared to steel or cast iron pipes. The strength of PSC pipe can be ...
Specifications of Prestressing Steel in Prestressed Concrete
Specifications of Prestressing Steel in Prestressed Concrete For prestressed concrete members, the high-tensile steel, used generally, consists of wires, bars or strands. The high tensile strength of steel is generally achieved by marginally increasing the carbon content in steel in ...
Prestressed Concrete Mix Design Proportions
Prestressed Concrete mix design proportions should be chosen in such a way that strength, durability, workability etc suits the construction. The mix proportions for prestressed concrete are determined based on the recommendations provided by the standard codes of the region. ...
Requirements of Prestressed Concrete
Strength and durability are the basic requirements of prestressed concrete. The prestressing levels are determined such a way that the structural member show desired performance safely and economically. Main requirements of prestressed concrete are explained in the below section. Requirements ...
Types of Prestressing Systems and Anchorages in Prestressed Concrete
In prestressed concrete structures, prestress is introduced by stretching steel wire and anchoring them against concrete. Therefore, the prestressing systems should comprise essentially a method of stretching the steel and a method of anchoring it to the concrete. Different systems ...
