Bonded PC strand with HDPE coating
Brief introduction of bonded prestressed steel strands
I. Definition and core structure
Basic concept: The steel strands are bonded to concrete as a whole through grouting. After tensioning, the channels are filled with cement slurry to form a coordinated force system.
Structural composition: It is composed of 7...
High Strength Unbonded Steel Strand for Construction
This product is suitable for cast-in-place concrete projects, such as cast-in-place slabs, geotechnical projects, foundation piles, slope support, etc. It has the characteristics of no need to reserve holes, easy construction, saving bellows materials, and random bending. Its application in recoverable anchor cables...
I. Product Introduction
1. Structure and Composition
Construction: Made of 7 high-strength steel wires twisted together, the outer layer is wrapped with a high-density polyethylene (HDPE) sheath, and the sheath and the steel strand are filled with grease to form a "non-bonding" state (that is, there is no bonding...
12.7 A brief introduction to unbonded prestressed steel strands
I. Basic concepts
12.7 Unbonded prestressed steel strands are a special type of steel used in prestressed concrete structures. Their "unbonded" characteristics mean that the steel strands are not directly bonded to the concrete, but isolated by a...
