See astm c173 air content by volumetric method.

Air content test concrete.

The only ingredient in the concrete that is compressible is the air. A sample of concrete is placed in the cylinder of an air meter in three layers each being fully compacted by hand or by vibration. Air entrained concrete is typically specified in areas of the country where frost related damage can occur. The method of testing is given in bs en 12350 7 which replaces bs 1881.

Method a outlines the principle of the test. Air entrained concrete is typically specified in areas of the country where frost related damage can occur. Entrapped naturally occurring in the mix entrained intentionally added to the mix. Cementitious material water and aggregates do not respond to the small rise in pressure.

Super air meter sam is a modified type b concrete air meter invented by tyler ley phd pe who promises the sam will change the way we view concrete s freeze thaw durability to read more about tyler see our tyler ley interview blog post with dr. It is intended to be a supplement to reading the astm as well as a study tool for the aci exam. This guide will teach you how to test air content of concrete with a type b pressure meter. 3 2 this test method and test method c138 c138m and c173 c173m provide pressure gravimetric and volumetric procedures respectively for determining the air content of freshly mixed concrete.

Entrained air is formed in concrete using a surfactant. So the pressure change is correlated to the air content of the concrete. It covers the reasons you are performing this test the equipment needed and the procedure of astm c231. This test method cannot be used for testing lightweight concrete because the aggregate in lightweight is too porous.

The measurement of air content in fresh concrete of normal density is typically performed using the pressure method another useful test is astm c 173 however the pressure method is frequently preferred because it is relatively fast. Pkf construction on turnpike i 95 concrete technician. The sam uses an extended test procedure to determine air content and characterize the size and distribution of air bubbles in. The smaller the bubble the stronger the bubble.

Two types of air.
