Our Concrete Permeability Tester is a state-of-the-art device designed to measure the permeability of concrete accurately and efficiently. This essential tool helps ensure the durability and longevity of concrete structures by providing precise data on how well concrete can resist water penetration. Key Features:The Perma2™ permeability tester has completely re-engineered lab tests devices for the measurement of the electrical resistance of concrete. The data estimates the chloride diffusion coefficient of concrete for the service life prediction and design of concrete structures. As well as the durability based quality control of concrete.
The European standard AT 315 apparatus determines concrete water permeability. Custom tests force water under pressure through concrete, with 25mm as the maximum allowable depth of water penetration. The constant head test directly measures the permeability coefficient of concrete. The transport of liquids, gasses, and aggressive agents into concrete is responsible for a variety of durability issues. To obtain the low-permeability concrete required for long-lasting .This fully automatic apparatus is designed to perform water permeability tests on cubic concrete specimens max 150 mm side and cylinder specimens max 160 mm diameter.. The specimens are submitted to hydrostatic stress for a pre-set period. The water permeated through the test specimen is directly collected and measured into a graduated cylinder.The permeability of concrete is a critical property that governs the rate at which fluids penetrate into a porous solid. It is primarily determined by the size and connectivity of pores within the concrete matrix, as well as the complexity of the pathways through which fluids travel. . Selecting and employing appropriate compaction equipment .
