Bridge Prestressing Material

 


Bridge Prestressing Material

We SCON INFRASTRUCTURE are Leading Manufacturers, Suppliers, Providers, Contractors and Services of Bridge Prestressing material. Because the yield strength of ordinary mild steel and deformed bars used in R.C.C. is not particularly high, they are not employed in PSC (Prestressed concrete). Many factors contribute to the decrease of prestress (about 20%) in the PSC. If mild steel or HYSD bars are utilized, there will be very little prestressed remaining after losses, and it will be useless to us. As a result, for prestressing, high tensile strength steel is employed. The steel used in prestressing must have a greater ultimate elongation in addition to its high strength. Tendons are high-strength tensile wires with diameters ranging from 1.5 to 8 millimeters. The ultimate tensile strength of steel wires used for prestressing is shown in the table. A strand or cable is made up of a group of wires that have been twisted together.


A cable or stand's total diameter ranges from 7 to 17mm. Post-tensioning systems make use of them. In prestressed concrete, high tensile steel bars with a diameter of 10mm or greater are also utilised. Because PSC uses high-tensile steel, the concrete utilized should be of excellent quality and strength. As a result, according to IS regulation, a minimum mix of M40 for pretension systems and M30 for post-tensioned systems is recommended. These concrete mixes have great strength and a high modulus of elasticity, resulting in minimal deflection. Smaller portions come from the use of high-strength concrete. High-strength concrete is resistant to strain, shear, bonding, and bearing forces. With greater strength concrete, there is less prestress loss. We SCON INFRASTRUCTURE are deeply engaged in offering a wide array of Bridge Prestressing material to our valuable Clients located in Mumbai, Navi Mumbai, Thane, and all over India.

Architectural Expansion Joints

  Architectural Expansion Joints We  SCON INFRASTRUCTURE   are Leading Manufacturers, Suppliers, Providers, Contractors, and Services of  Architectural Expansion Joints . An expansion joint is a mid-structure separation in building construction that is meant to alleviate stress on building materials produced by building movement caused by: - thermal expansion and contraction caused by temperature variations, - wind sway, - seismic occurrences, and so on. Leave a gap between your floor and the baseboard or wall when putting laminate or hardwood flooring. The expansion gap is a space that allows the laminate or wood floor to expand or shrink. EXPANSION is a word that has a lot of different meanings. Building faces, concrete slabs, expand and contract due to seasonal variation or other heat sources. JOINT or movement joint an assembly designed to safely absorb the heat-induced expansion and contraction of construction materials, to absorb vibration, to hold parts togeth...

Rock Anchoring

  Rock Anchoring We  SCON INFRASTRUCTURE   are Leading Manufacturers, Suppliers, Providers, Contractors and Services of  Rock Anchoring . To comprehend the notion of rock anchoring, one must first understand what rock anchors are. A rock anchor is a high-strength steel tendon with a stressing anchoring on one end and a method of transmitting force to the grout and rock on the other. A hole of the correct length and diameter is bored, and the rock anchor tendon is inserted and secured to the rock. To perform a successful rock anchoring, certain factors must be considered, such as the service life of an anchor, the design load per anchor, the type of soil and rock encountered with respect to depth, undrained shear strength and bulk density at various depths, and rock permeability, among others. The primary goal of rock anchoring is to strengthen the foundation of a building and prevent it from shifting. Several variables, including hydrostatic pressure, wind loads, and...
