Description
Product Introduction:
The mortar push‑out tester complies with the requirements of GB/T 50315, “Technical Standard for On‑Site Testing of Masonry Works,” and is suitable for estimating the compressive strength of masonry mortar in walls constructed with 240 mm‑thick sintered common bricks, sintered porous bricks, autoclaved aerated concrete bricks, or autoclaved fly ash bricks. The instrument uses a worm‑gear transmission to apply force through a cover plate onto the masonry units, thereby assessing masonry strength. It consists of a strain‑gauge pressure sensor and a display circuit. When subjected to load, the pressure sensor generates an electrical voltage signal, which is converted into a digital signal by a 24‑bit A/D converter and processed by an MCU before being displayed on an LCD. The test results are highly intuitive, though the testing process may cause localized damage to the specimen.
Product Features:
① This instrument features a novel design, a compact size, lightweight construction, and user-friendly operation.
② Manual loading is employed, making operation simple and convenient.
③ Liquid crystal display pressure gauge, enabling direct reading of the peak shear force.
