The Mortar Permeability Apparatus comprises brass / Gun Metal Cells mounted on a stand and a pressure chamber with a pressure regulator. The cell can accommodate 100mm Dia x 50mm High Specimen. Each Cell assembly consists of one base plate. The base plate has one outlet for water and recessed to hold the specimen in place with ring washer in between. The top plate has an inlet for water and a suitable connector for the application of pressurized water in the cell. The mould and collar are clamped between the base plate and the top plate with the help of four tension rods and nuts. The cells are mounted on a stand. The pressure chamber is fitted with a pressure regulator, which helps in regulating the pressure from 0-7 kg / cmÂ². The regulator has two pressure gauges, one for indicating the pressure in the chamber (0-10.5kg / cmÂ²) and the other for indicating the testing pressure (0-7kg / cmÂ²). The Pressure Chamber is connected to the cells with pressure hoses and with couplings. This pressure chamber is fitted with Schrader valve.
