HSP-355 Type Concrete Shrinkage and Expansion Compensator
This is a specialized testing instrument primarily used to determine the longitudinal restrained expansion and longitudinal restrained drying shrinkage of compensating concrete. It complies with the requirements of GB 50119-2003, “Technical Specification for the Application of Concrete Admixtures.”
KENTc-6 Type Concrete Permeability Electrical Tester (Electrical Flux)
The KENTC series concrete permeability electrical meter complies with China’s port engineering standard JTJ 257‑2000 and the U.S. ASTM C1202 standard. It is commonly referred to as the electrical‑charge method, which is also the method specified in China’s port engineering standard JTJ 275‑2000. In this method, a 60‑V DC voltage is applied across the two ends of a φ95 × 50 mm concrete specimen, and the concrete’s permeability is assessed by measuring the total electric charge that flows through the specimen over a 60‑hour period.
HPC-001S Fresh Concrete Comprehensive Performance Tester
It is possible to determine slump, water‑cement ratio, compressive strength, and temperature on site within minutes, and to estimate the 28‑day strength.
SR-9 Concrete Thickness Tester
It is based on the principle of impact‑echo and is used to measure the thickness of single‑sided concrete. It is primarily employed for measuring the thickness of floor slabs, wall panels, tunnel concrete, pavement concrete, and various other types of concrete.
