National Building Materials Testing Center is one of the national comprehensive analysis and testing center in 1984 10 menstrual former State Science and Technology Commission approved the establishment of 13. After years of continuous development and improvement efforts, has developed into a center for the entire building materials industry, engaged in building materials and inorganic non-metallic materials analysis and testing research and testing, arbitration services. Center is the only comprehensive testing capability with the building materials testing organization, is one of the National Certification and Accreditation Administration first approved by the 29 decoration materials harmful substances testing agency, the state commission designated mandatory certification porcelain tile testing laboratory, is the Ministry of Science and the State Administration of Quality Supervision, Inspection and Quarantine approved by the detection and identification of scientific and technological achievements of national testing agencies. Building structure testing room as a national building materials testing center and one of the professional building materials testing room National Quality Supervision and Inspection Center, with complete reinforced concrete structure, masonry structure test research capacity, steel engineering testing assessment. With advanced engineering test equipment more than 100 sets of: non-metallic ultrasonic testing analyzers, radar detector concrete structure, reinforced concrete detector, floor thickness, crack width gauge, multi-functional strength tester, concrete Hammer, mortar Hammer, Hammer brick measured in situ presses, bolt tension meter, ultrasonic and magnetic detectors, high-strength composite torque bolt axial force detector, high-strength bolts axial force intelligent detector, coating thickness gauge, Rockwell hardness, fasteners torsional strength testing machine, testing machine and other types of mechanical fasteners reinforced concrete structure, masonry and steel structure detection equipment; Infrared heat flow and temperature data logging devices, FlowHood , according to meter, temperature recorder, ultrasonic flowmeter testing instruments and other energy projects. Building structure detection chamber has strong technical strength, to provide accurate, scientific and impartial testing services advanced engineering test equipment and rich experience for customers. Test items: 1, the main structural engineering field testing of concrete, mortar, masonry strength field test; concrete strength by rebound method, ultrasonic synthesis methods, drill core assay; reinforced concrete structure location, diameter, thickness of the protective layer, reinforced corrosion is detected; concrete and reinforced internal defects (holes, not dense areas, cracks, embedded pipeline technology) non-destructive testing; rebound method, penetration method mortar compressive strength of masonry structural engineering field testing; situ axial compression assay masonry strength; concrete surface permeability testing; massive concrete temperature - stress and strain monitoring. 2, steel works special testing of welding quality (ultrasonic method, MT, PT) non-destructive testing; steel corrosion coating and fire detection; deformation detection steel truss structure; truss rod and the mechanical properties of the ball node detection; Steel node, mechanical connection performance testing using standard mechanical fastening; steel with high-strength bolts mechanical properties testing (tensile strength, hardness, torque coefficient, anti-slip coefficient); National Building Materials Test Center Address: Chaoyang District, Beijing Bones in One Tube
