Book Synopsis Bubblepoint Testing of Geotextiles by : DJ. Elton
Download or read book Bubblepoint Testing of Geotextiles written by DJ. Elton and published by . This book was released on 2007 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: A simple, inexpensive device for measuring geotextile pore sizes, using ASTM D 6767, is described and its operation is outlined with guidance for correct operation. The accuracy and consistency of the test are shown. The test appears to have better consistency than the apparent opening size (AOS) test, avoids the inherent and operator-dependent problems of theAOS test, and further, describes the entire pore size distribution of a geotextile, making it useful for developing a more complete filter criterion. Suggestions are made for improving ASTM D 6767.
Book Synopsis Comparative Evaluation of Geotextile Pore Sizes Using Bubble Point Test and Image Analysis by : AH. Aydilek

This book was released on 2007 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: Analysis of the filtration performance of a geotextile filter necessitates accurate information about the size distribution of geotextile pore openings. The effectiveness of the bubble point test in determining the pore and constriction sizes of geotextiles was evaluated. The characteristic woven geotextile pore and nonwoven geotextile constriction sizes, O95, were determined for a variety of specimens and compared with both the manufacturers' reported AOS values, and with those determined from the two previously developed image-based procedures and theoretical equations. The results indicated that the O95 sizes of woven mono and multifilament geotextiles determined by image analyses compared well with the AOS values, whereas the same observations were not made for the bubble point-based O95 sizes. The O95 constriction sizes of various nonwoven geotextiles obtained by the bubble point test were not comparable to the manufacturers' reported AOS values, indicating the limitation of ASTM D 4751 in determining constriction sizes. A direct method, such as image analysis, may be a better approach for determining the pore sizes of woven geotextiles, whereas the bubble point method should be preferred to determine constriction sizes in a nonwoven geotextile. Recommendations are made in regard to improvements in the current ASTM standard on bubble point testing.

Book Synopsis Residual Fluid as a Source of Error in Bubble Point Testing by : David Elton
Download or read book Residual Fluid as a Source of Error in Bubble Point Testing written by David Elton and published by . This book was released on 2009 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: The bubble point test (ASTM D6767) is a method of calculating the pore size distribution of geotextiles. ASTM D6767 allows a variety of wetting fluids to be used in the test. However, different fluids are found to produce different pore size distributions, even though relevant fluid properties are supposedly accounted for in the data reduction (Elton, D. J., Hayes, D. W., Adanur, S., Geotech. Test. J., Vol. 30, No. 1, 2007, pp. 9-16). The ASTM D6767 data reduction is found to be theoretically incorrect. The effect of residual wetting fluid on the pore size distribution is examined. Residual fluid is defined as fluid that remains on the walls of a previously saturated pore after the critical pressure for the fluid in the pore has been reached (after the bubble point pressure is reached). Since the phenomenon of residual fluid is not considered in ASTM D6767, it presents a source of error. Bretherton's law suggests residual fluid errors will be reduced by using fluids with a small viscosity to surface tension ratio.
Book Synopsis Application of the Bubble Point Method to the Characterization of the Pore-Size Distribution of Geotextiles by : SK. Bhatia
Download or read book Application of the Bubble Point Method to the Characterization of the Pore-Size Distribution of Geotextiles written by SK. Bhatia and published by . This book was released on 1995 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: For the design of a geotextile as a filter, reliable information about the pore-size distribution of the geotextile is needed. The bubble point method is one technique that is able to provide this information for a geotextile. The bubble point method is a simple and rapid technique for evaluating pore-size distributions of virgin, clogged, and stretched geotextiles. In addition, the bubble point equipment is also capable of providing information as to the degree of clogging within a geotextile and the permeability of a geotextile. The geotextile pore-size distribution results obtained by the bubble point method showed good repeatability. However, the bubble point method was only able to distinguish between geotextiles that had significantly different cross sections. Pore-size distribution results for geotextiles with similar cross sections, but of increasing thickness, were very similar. The dry sieving (ASTM D 4751), hydrodynamic sieving (CAN/CGSB-148.1-10), AND WET SIEVING (sw-640550-83) METHODS ARE GENERALLY only useful for evaluating the larger pore openings (O95, O90) of the geotextiles. In addition, the methods are time consuming. The mercury intrusion porosimetry method (ASTM D 4404) was also performed; however, there was little difference in pore-size distribution results for any of the 28 different geotextiles tested (Smith 1993). There are also environmental concerns with using mercury. The bubble point method showed potential for characterizing the pore-size distribution of geotextiles.

Book Synopsis Evaluating Geotextile Pore Structure by : BR. Christopher
Download or read book Evaluating Geotextile Pore Structure written by BR. Christopher and published by . This book was released on 1996 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are many test methods available to determine the pore sizes of geotextile filters. Often overlooked is the fact that each method provides a different interpretation of a geotextile's pore structure. A survey of the available test methods, indicates that four categories of pores can be measured. Pore characteristics are identified by one of the following methodologies: sieving, theoretical, volumetric, and numerical. A critical review of the data produced by these methods shows that the actual pore structure as related to flow-through behavior can only be determined by the bubble point method, which provides a volumetric pore size. This test identifies the constriction size of each pore channel in a geotextile, where retention and clogging are most critical. The bubble point test method is advantageous because it provides for the complete pore size distribution of the geotextile, can be performed more efficiently than sieving methods, and provides an accurate estimate of the permeability of the geotextile.
