Concrete Permeability Apparatus

The design of concrete mix aims at maximum durability for the conditions prevailing at the site where it is to be used. ability to resist the flow of water through, is one of the important durability characteristics. The permeability is determined on cement. mortar and concrete specimens, either cast in the laboratory or obtained by cutting out cores from existing structures.Permeability CellConsists of a metal cylinder with a ledge at the bottom for retaining the specimen, a flange at the top, removable cover plate and a funnel. A rubber gasket is seated in matching grooves, between the cell and the cover plate, to render the joint water tight. Internal working size of the cell will be 100mm dia X 100mm hight.Water ReservoirConsists of a length of metal pipe, 50 to 100 mm in diameter and about 500 mm long. The reservoir fitted with a graduated side arm gauge-glass for admitting water and compressed air and a cock for drainage, bleeding and connection to the permeability cell.Pressure LinesHeavy duty armored rubber hose with end fittings. Complete with glass bottles but without compressor. For specimen size 100 X 100 mmConcrete permeability tester for three specimen of (100mm dia x 100mm height) or (150mm dia x 150mm height) or (150mm cube) is also available.
