tensile stresses,and protection of the strand or wire in unbonded systems.It did not include specific require-ments for the protection system,other than that the prestressing steel be coated with a gr ease,wax,or asphalt-impregnated material and enclosed in aBonded PC Strand - pt-concrete1.Bonded PC Strand are mainly used for prestressed steel structure,a variety of rail and road bridges,factory plant,high-rise building,prestressed construction and a variety of building foundation columns and the transformation of reinforcement,the city's overpass,Shell safety of nuclear power stations,television tower,water towers,concrete silo,sewage treatment,anchoring the rock China Mono Strand Anchorage Plate for Unbonded Steel Mono strand anchorage plate for unbonded steel strand cable .Definition of Parts Anchor head is the key part of bearing the prestressing tension,The round anchor head is made by 45# high-quality carbon construction steel,and the flat anchorage is made by 40Cr steel.

published a new Standard,Specification for Unbonded Single-Strand Tendon Materials (ACI 423.7-141). This is an extremely important document with major ramifications for the post-tensioning (PT) industry.It is a referenced standard in Section 3.2.2 of the ACI Building Code (ACI 318-142).As a referenced part of the Code,the Specifica-Post TensioningThese days post tensioning uses low relaxation 7-wire high tensile steel PC strand as prestressing tendons.By using these high tensile steel strand,we can greatly reduce the usage of non-prestressed reinforcement steel,typically with a ratio of 1 3 or 4.This allows us to have a better utilisation of materials in the course of construction.Some results are removed in response to a notice of local law requirement.For more information,please see here.12345Next
