Chongqing: Sharing Knowledge on Bidirectional Plastic Geogrid Testing
Release date:
2020-12-14
Chongqing Bidirectional Plastic Geogrid Quality testing is a matter of concern for all relevant parties—such as manufacturers, distributors, procurement units, and government regulatory agencies—all of whom require a qualified test report for Chongqing’s bidirectional plastic geogrids. For engineering applications, the quality of the geogrid must meet the specific mechanical performance criteria required by the project, particularly in terms of stress-strain relationships. Meanwhile, factors like the product’s raw material formulation, manufacturing processes, processing equipment, and quality control methods can all potentially influence its final performance. Chongqing Bidirectional Plastic Geogrid Quality makes a difference. This is precisely when we need to rely on testing—and, based on the extensive scientific data we gather—to make informed judgments about its performance.
In our country, Chongqing Bidirectional Plastic Geogrid The testing standard is GB/T 17689-2008 "Geosynthetics – Chongqing Bidirectional Plastic Geogrids," as specified in GB/T 17689-2008. Chongqing Bidirectional Plastic Geogrid The products are primarily used as soil reinforcement or stabilization materials in engineering construction. They are mainly categorized into uniaxial tensile types. Chongqing Bidirectional Plastic Geogrid Two types: bidirectional stretch and bidirectional plastic geogrids from Chongqing. Chongqing Bidirectional Plastic Geogrid Geogrid products are typically made using high-density polyethylene or polypropylene as the primary raw material. Notably, GB/T 17689-2008 does not apply to the testing of plastic-reinforced geogrids produced by welding reinforcing strips, as well as chemical fiber geogrids and glass fiber geogrids.
In addition to the standard size deviation assessment and sensory evaluation. Chongqing Bidirectional Plastic Geogrid The carbon black content must be no less than 2.0 percent. In terms of creep performance, the measured creep conversion factor *bi* must meet the service life requirements specified in the engineering design. Meanwhile, for the most critical mechanical properties, GB/T 17689-2008 mandates testing of key indicators, including tensile strength, tensile strength at 2% elongation, tensile strength at 5% elongation, and nominal elongation. Additionally, if the material is a biaxially oriented polypropylene plastic geogrid, both longitudinal and transverse tensile tests are required.
Chongqing Bidirectional Plastic Geogrid In addition to the national standard GB/T 17689-2008, there is also QB/T 5303-2018, "Geosynthetic Materials—Four-Directional Tensile Strength." Chongqing Bidirectional Plastic Geogrid 》industry standard. This standard primarily focuses on Chongqing’s bidirectional plastic geogrids with a planar, four-way grid structure made from polypropylene as the raw material. The testing procedures for the four-way stretched Chongqing bidirectional plastic geogrids are essentially identical to those specified in GB/T 17689-2008—except that an additional secant modulus indicator is required when measuring the 2% and 5% elongation rates. Additionally, if you wish to evaluate the creep performance of Chongqing’s bidirectional plastic geogrids, you can also conduct the tests according to QB/T 2854-2007, "Method for Creep Testing and Evaluation of Bidirectional Plastic Geogrids."
