    LC-546 Type Mortar Air Content Tester

    LC-546 Type Mortar Air Content Tester

    According to the gas law, when a pressure‑equalizing valve is opened or closed between a gas chamber maintained at a constant pressure and a container filled with the test specimen, the pressure in both containers eventually reaches equilibrium. The reduction in pressure of the gas chamber corresponds to the percentage of air content in the mortar, and this value is indicated on the pressure gauge as the air content of the specimen.

    JLD-8538 Pressure-Selection Method Mortar Strength Tester

    JLD-8538 Pressure-Selection Method Mortar Strength Tester

    This instrument is used to determine the compressive strength of masonry mortar. It operates by selecting representative horizontal mortar joints in a masonry structure, extracting mortar core samples to fabricate test specimens, and then subjecting these specimens to a compression test using a compression tester. The measured compressive load is subsequently used to estimate the compressive strength of the masonry mortar. The device complies with the standard requirements of JGJ/T 234-2011, “Technical Code for Determining the Compressive Strength of Masonry Mortar by the Compression Method.” It provides real-time force readings, automatically records peak values, supports data storage and retrieval, and is portable with a rechargeable battery.
