The primary materials used for inducing prestress in a pre-stressed concrete (PSC) framework comprise prestressed concrete wire and PC strands.

Low relaxation PC stranded wire refers to the principle that pre-stress steel strands embedded within concrete gradually diminish the applied tension over time in a predictable mathematical ratio. The PC strand, or prestressed concrete strand, is characterized as a high-quality, low-relaxation material.

Applications:

PC strands are extensively utilized in precast concrete structures for both pre-tensioning and post-tensioning. Their widespread application makes them almost indispensable in prestressed concrete construction.

Manufacturing Process:

Pre-stressing involves incorporating high tensile strength steel strands or bars, often called tendons, to enhance concrete or similar construction materials. The process of imparting pre-stress to the tendons can be executed using one of the following methods:

• 1) Stretching the tendons;
• 2) Applying force to the tendons against the concrete; or
• 3) Simultaneous extension and compression.

Advantages of Launching a Low Relaxation Pre-Stressed Concrete Steel Strand (LRPC) Business:

Launching your own venture in the Low Relaxation Pre-Stressed Concrete Steel Strand (LRPC) market offers numerous advantages. Not only will you be your own boss, but you will also have complete control over your operations. There is a substantial potential for financial gain, as LRPC businesses can be remarkably profitable.

PC Strand, also known as prestressed concrete steel strand, is a twisted assembly of high-strength steel wires, which typically come in configurations of 2, 3, 7, or 19 strands, all designed for use in prestressed concrete applications.

Classification

PC strands can be categorized based on the number of steel wires they contain: such as 2-wire strand, 3-wire strand, 7-wire strand, and 19-wire strand. Additionally, classifications can be made regarding the surface characteristics, resulting in smooth steel strands, scoring strands, mold pulling strands (compact), and those coated with epoxy resin.

Specifications

In technical documentation, you may encounter specifications such as 15-7φ5, 12-7φ5, and 9-7φ5 for prestressed steel strands. For instance, in the case of 15-7φ5, the '5' denotes a wire diameter of 5.0mm, while '7φ5' indicates a strand made up of seven steel wires, and '15' represents the total diameter of each strand at 15mm, summing to a total of 'seven strands of 15 mm diameter', which equals approximately 15.24 mm when dimensions are considered with tolerances.

Materials

The strands are produced from high-carbon steel wire rod, which undergoes surface treatment before being cold drawn into wires. These wires are then combined to form strands. A stabilization process alleviates stresses to enhance longevity, while wire coatings (metallic or non-metallic, such as galvanized and epoxy resin) may be applied. Surface texturing can further enhance adhesion to the concrete, and the manufacture of unbonded prestressed steel strands typically involves coating ordinary prestressed steel wire, wrapping it in high-density polyethylene (HDPE) bags.

Features

The notable characteristic of prestressed steel strands lies in their superior strength and relaxation performance. Common tensile strengths range widely, with yield strengths being especially high.

Applications

Smooth steel strand finds extensive usage in both post-tensioned and pre-tensioned prestressed projects. Its applications reach into nuclear facilities and similar projects. Additionally, galvanizing is typical for strands functioning as tie rods in bridges and for external prestressing projects, whereas epoxy-coated wire serves a role akin to galvanized prestressed steel wire.

Standards

Various countries have established standards for prestressed strands, including China's GB / T, the American ASTM A416, British BS standards, Japan's JIS G, Australia's AS / NZS, and Brazil's NBR.
