Concrete Air Content Test Equipment

The h 2783 concrete air meter this easy to use meter features humboldt s all brass super pump the most reliable and highest quality pump available.

Concrete air content test equipment.

This guide will teach you how to test air content of concrete with a type b pressure meter. Rebar electronic metal detector. Fresh concrete testing equipment ensures that concrete is delivered as specified for high quality pavements and structures. The super concrete air meter measures both the air void spacing and air volume of fresh concrete.

Concrete air meters and indicators for air entrainment are used for determination of air content specific gravity and free moisture test of aggregates. Concrete air meters measure the air content of fresh concrete in accordance with astm and aashto standards test methods. Equipment includes tools for measuring slump air content and unit weight of conventional concrete mixes. The super air meter uses two sequential pressurizations to test the concrete air content.

The h 2784 super air meter this high quality air meter measures air void spacing and air volume of fresh concrete to help users better understand the freeze thaw durability of fresh concrete. Pad cap quick release powder. It is intended to be a supplement to reading the astm as well as a study tool for the aci exam. Gilson offers a selection of air meters for use in testing fresh concrete specimens or concrete mixes lightweight aggregate concrete or other lightweight mixes.

The smaller the bubble the stronger the bubble. Passing ability of self consolidating concrete equipment accessories for consolidation strike off temperature. Entrained air is formed in concrete using a surfactant. We have concrete air meters and roller meters for testing air content.

So the pressure change is correlated to the air content of the concrete. The air meter investigates the deformation of the concrete at 14 5 30 and 45 psi. Myers also supplies cylinder molds and compression machines for testing strength. The only ingredient in the concrete that is compressible is the air.

Concrete air meters and indicators are astm 231 compliant and are part of a complete line of concrete testing equipment available from humboldt. Cementitious material water and aggregates do not respond to the small rise in pressure. All supported by u s. In addition there is a variety of non destructive strength testing equipment including the windsor probe rebar locators crack monitors.
