The "Patch Guard Method" is an effective sacrificial anode material for preventing re-deterioration of repaired sections and suppressing corrosion of reinforcing steel due to the effects of salt damage and carbonation. The sacrificial anode material works by the difference in ionization tendencies between "zinc" and "iron," where zinc (the sacrificial anode material) ionizes (rusts) before iron (the reinforcing steel), thereby suppressing the corrosion of iron. Common materials that utilize this effect include "zinc-coated steel plates." 【Features】 ■ Excellent power generation performance ■ High rust prevention effect ■ Uses titanium with excellent corrosion resistance and durability ■ Easy to install ■ Does not require additional hanging *For more details, please refer to the PDF document or feel free to contact us.

Our company conducts investigations and diagnostics of concrete structures. "Soft Coring" allows for estimating the concrete strength of structures with a precision comparable to that obtained from compressive strength tests of core samples ranging from approximately 20mm in diameter to 100mm in diameter.

The "Table Vibrator (for Wet Screening of Concrete)" is a product developed in-house by New Tech Co., Ltd., which conducts investigations and diagnostics of concrete structures. It is specifically used for wet screening concrete in unit water content estimation tests. When wet screening fresh concrete to estimate the unit water content of the concrete using its mortar, differences arise between the moisture of the mortar adhering to aggregates that remain at 5mm and the moisture of the mortar that is 5mm or smaller, with the moisture of the mortar adhering to the 5mm aggregates being greater. Ultimately, it is necessary to correct that difference, and this device was developed to ensure stable mortar quality when determining that correction factor. Traditionally, this process was mostly done manually, and this device helps reduce the time required for the task. 【Features】 ■ Used for wet screening concrete in unit water content estimation tests ■ Reduces work time *For more details, please feel free to contact us.
