About Permeability Apparatus

Permeability Apparatus-Are used 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.

Specifications: The concrete permeability apparatus comprises of a 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 selves packed valve and rubber hose pipe with end connections. The cell assembly consists of one base plate, one metal funnel and one top plate. The pressure chamber is fitted with a pressure regulator which helps in regulating the pressure from 0-15kg/cm sq. gauge is for indicating the pressure in the cell. A foot pump and a pressure tube is supplied to develop pressure in the chamber. The apparatus is supplied with a measuring cylinder 500 cc to measure percolated quantity of water.

Versatile Testing for Varied Soils

This permeability apparatus is uniquely designed to test different soil typesincluding clay, sand, and silt. Its dual falling head and constant head test methods allow for versatile application in academic research, professional geotechnical analysis, and construction material testing labs, ensuring reliable results across a broad range of soil conditions.

Precision and Durability Combined

With a 7.5 cm diameter sample holder and a transparent borosilicate glass tube, the device offers high-visibility measurements and 0.5 mm water head reading accuracy. The sturdy powder-coated mild steel frame and polished stainless steel components ensure corrosion resistance and a long service life, making it a robust choice for everyday lab environments.

FAQs of Permeability Apparatus:

Q: How does the Falling Head Permeability Apparatus operate for soil testing?

A: The apparatus uses falling head and constant head methods to measure soil permeability. Water flows through a soil sample held in a cylindrical chamber; changes in water level or constant flow rate are recorded via a graduated borosilicate glass tube, delivering highly accurate results for different soil types as per IS: 2720 Part XVII and ASTM D2434.

Q: What features ensure durability and precision in this permeability apparatus?

A: Manufactured with a powder-coated mild steel frame, polished stainless steel fittings, and borosilicate glass tubes, the apparatus is corrosion-resistant and temperature-tolerant. The transparent measuring tubes, brass valves, and accurate scale (0.5 mm) guarantee both longevity and dependable measurements in laboratory settings.

Q: When should I use the falling head method versus the constant head method?

A: The falling head method is ideal for low-permeability soils like clays, while the constant head method is suited for high-permeability soils such as sands. Choosing the appropriate test method allows for accurate permeability calculations based on the soils drainage characteristics.

Q: Where is this permeability apparatus commonly utilized?

A: This apparatus is widely used in soil mechanics, geotechnical engineering labs, construction quality control, and academic research institutions in India and internationally. Its compliance with recognized standards ensures its applicability worldwide wherever rigorous soil permeability testing is needed.

Q: What is included with the permeability apparatus for setup and operation?

A: Accessories include a measuring jar, connection tubing, valve set, and all necessary brass connectors. The stainless steel stand and borosilicate glass canister are included for reliable experimental arrangement. The unit is manual by default, with the option to use an electric water pump if desired.

Q: How does this equipment benefit laboratory testing and research?

A: By enabling precise, repeatable soil permeability measurements in compliance with industry standards, this apparatus supports sound geotechnical analysis, construction site investigation, and academic study. Its robust construction and transparent scale increase both the accuracy and efficiency of laboratory operations.
