This guide will teach you how to test air content of concrete with a type b pressure meter.
Concrete air content test equipment.
Concrete air meters and indicators are astm 231 compliant and are part of a complete line of concrete testing equipment available from humboldt.
Myers also supplies cylinder molds and compression machines for testing strength.
The super concrete air meter measures both the air void spacing and air volume of fresh concrete.
Fresh concrete testing equipment ensures that concrete is delivered as specified for high quality pavements and structures.
We have concrete air meters and roller meters for testing air content.
All supported by u s.
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.
It covers the reasons you are performing this test the equipment needed and the procedure of astm c231.
Forney has all the high quality materials science equipment accessories and specialty tools you need to crush crack pull twist and test.
The only ingredient in the concrete that is compressible is the air.
So the pressure change is correlated to the air content of the concrete.
Cementitious material water and aggregates do not respond to the small rise in pressure.
In addition there is a variety of non destructive strength testing equipment including the windsor probe rebar locators crack monitors.
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.
The smaller the bubble the stronger the bubble.
Entrained air is formed in concrete using a surfactant.
Passing ability of self consolidating concrete equipment accessories for consolidation strike off temperature.
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.
Pad cap quick release powder.
Construction materials testing equipment what can we break for you today.
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.
It is intended to be a supplement to reading the astm as well as a study tool for the aci exam.
