Available in PDF, EPUB and Kindle. Book excerpt: A high-pressure test apparatus and method developed from one originated by the Illinois Division of Highways was studied at the WATERWAYs Experiment Station using concrete cylinders 6 in. in diameter and 12 in. in eight. In this method a specimen is submerged in water in a strong sealed container and subjected to 4000-psi hydraulic pressure. The ensuing apparent volume change is used to determine the amount of air present in the specimen. (Author).

Download or read book Plastic Air Content Versus Hardened Air Content by High Pressure Air Meter written by Todd Hanson and published by . This book was released on 2001 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plastic air content is typically tested by the pressure method, ASTM C138. Loss of air content through the paver has been shown to exceed 2 percent at times. Research has shown that early deterioration of pavements in Iowa may be directly or indirectly related to low or inadequate air content. Hardened air content is typically checked using the linear traverse method, ASTM C457. The linear traverse method is very time consuming and could not be used on a production scale. A quick and effective method of testing in place air content is needed. Research has shown a high degree of correlation with the high-pressure method of determining air content of hardened concrete versus plastic air content in laboratory conditions. This research indicated that air contents are more variable when comparing core results to plastic air content, although the overall average for the air content was comparable. Perhaps, the location of the plastic air content test, obtained from construction records, versus location of the cores was not as accurate as needed.
