One of the durability tests of concrete is to determine permeability of water through specimen. Permeability apparatus is used for determining the permeability of cement mortar and concrete specimens of 15cm cubes cast in the laboratory
Specification:
The concrete permeability apparatus comprises of a brass/ gunmetal cell of squares cross section mounted on a stand and a pressure chamber is connected to the cell through copper tubing and T-connector mounted on the stand with sleeve packed valve and rubber hose pipe with end connections. The cell assembly consists of one base plate, one metal funnel and one top plate, and a pressure tube is supplied to develop pressure in the chamber. The apparatus is supplied with a measuring cylinder 500cc to measure percolated quantity of water. Pressure can also be applied by a pressure air line or by a compressor. This is supplied with three individual cells with stand. Three pressure gauges for indicating pressure in each cell are supplied apart from the main pressure gauge which indicates pressure in chamber.
Available for three samples of size 150mm dia X 150mm high.
Available for three samples of size 100mm dia X 100mm high.
