What are the quality check points of geotextiles and geogrids?

Geotextile, also known as geotextile, is a permeable geosynthetic material made from synthetic fibers by needling or weaving. Geogrids are divided into four categories: plastic geogrids, steel-plastic geogrids, fiberglass geogrids, and warp-knit polyester geogrids. The grid is a two-dimensional grid or a three-dimensional grid screen with a certain height, which is made of polypropylene, polyvinyl chloride and other polymers through thermoplastic or molded plastic. When used in civil engineering, it is called geotechnical grid. Geotextiles and geogrids are widely used geotechnical materials. What aspects of performance testing are generally required to ensure their quality? bv7Textile Testing Instruments, Testing Equipment Manufacturer

① Tensile strength: In the tensile test, the maximumThe stress that the sample experiences before it breaks is the tensile strength, which is known in science as the tensile strength. bv7Textile Testing Instruments, Testing Equipment Manufacturer

② Elongation: The elongation is the percentage of the ratio of the total deformation of the gauge section after tensile failure of the specimen to the original gauge length. bv7Textile Testing Instruments, Testing Equipment Manufacturer

③ Tear Strength: This is a term defined in a test method to measure the tear strength of a film or sheet. This procedure involves a tear test, which is carried out on a special testing machine with a test cut with a specified tear. bv7Textile Testing Instruments, Testing Equipment Manufacturer

⑦Infiltration coefficient: The infiltration coefficient is also called hydraulic conductivity. In isotropic media it is expressed as a unit flow rate under ddefined by a unit hydraulic gradient, which indicates the difficulty with which fluid flows through the pore skeleton. bv7Textile Testing Instruments, Testing Equipment Manufacturer

Geogrid routine tests include: appearance, physical properties (including: mass per unit area measurement, amplitude measurement, mesh size measurement); mechanical properties (including: strip tensile test, joint/seam broad strip tensile test, weld). bv7Textile Testing Instruments, Testing Equipment Manufacturer
