Concrete Air Content Test Equipment
Cementitious material water and aggregates do not respond to the small rise in pressure.
Concrete air content test equipment. It is intended to be a supplement to reading the astm as well as a study tool for the aci exam. The super concrete air meter measures both the air void spacing and air volume of fresh concrete. 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. The super air meter uses two sequential pressurizations to test the concrete air content.
In addition there is a variety of non destructive strength testing equipment including the windsor probe rebar locators crack monitors. The smaller the bubble the stronger the bubble. Passing ability of self consolidating concrete equipment accessories for consolidation strike off temperature. Concrete air meters and indicators for air entrainment are used for determination of air content specific gravity and free moisture test of aggregates.
It covers the reasons you are performing this test the equipment needed and the procedure of astm c231. 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. So the pressure change is correlated to the air content of the concrete. The only ingredient in the concrete that is compressible is the air.
All supported by u s. Fresh concrete testing equipment ensures that concrete is delivered as specified for high quality pavements and structures. Construction materials testing equipment what can we break for you today. This guide will teach you how to test air content of concrete with a type b pressure meter.
Concrete air meters measure the air content of fresh concrete in accordance with astm and aashto standards test methods. Rebar electronic metal detector. We have concrete air meters and roller meters for testing air content. Pad cap quick release powder.
Myers also supplies cylinder molds and compression machines for testing strength. 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 air meter investigates the deformation of the concrete at 14 5 30 and 45 psi. Equipment includes tools for measuring slump air content and unit weight of conventional concrete mixes.
