This book was released on 1973 with total page 6 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this study was to determine the effect of certain factors on test results when using ASTM Methods C 348 and C 349. For this purpose, four series of 3 mortar mixes each were made, and companion test specimens were molded using both hand tamping and vibrating methods. The results showed that, (1) Compaction of mortar test prisms by hand tamping produced densities which increased from the center towards both ends of the prism by an average of 2.1 percent; whereas this increase for prisms which were compacted by vibration averaged only 0.3 percent: (2) Compressive strengths by modified cube tests at the end locations averaged 5.6 percent higher than those at the middle of broken halves of the prisms compacted by hand tamping, but there was only 0.7 percent difference in strengths for the prisms compacted by vibration (Series IV): (3) The density of prisms compacted by vibration was, on the average, 3 percent less than that of tamped prisms. However, their flexural strength, on the average, was 8.5 percent higher than that of prisms compacted by tamping. (4) In comparison with standard 2-in. (50 mm) cube strengths, the compressive strengths of modified cube tests at the middle of broken halves and at the end of the prism averaged 96.0 and 101.7 percent, respectively, for tamped or 96.2 and 96.8 percent, respectively, for vibrated test specimens.

Book Synopsis Use of Ruggedness Testing to Develop an Inter-Laboratory Testing Protocol for Mortar-Cement Mortar by : LG. Ponce
Download or read book Use of Ruggedness Testing to Develop an Inter-Laboratory Testing Protocol for Mortar-Cement Mortar written by LG. Ponce and published by . This book was released on 1999 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1996, ASTM approved a specification for a new product, called mortar cement, intended for use in applications requiring masonry with high tensile bond strength. An inter-laboratory testing program is planned; the objectives will include the determination of intra- and inter-laboratory coefficientsof variation of bond-wrench results for that product. Prior to conducting the inter-laboratory testing program, it is necessary to set the test procedures and variables to be used. Some of those procedures (such as the precise control of flow, the use of jigs, templates and drop hammers to construct prisms, and bag curing), have already been found to reduce the variability of bond-wrench results, are included in ASTM C1329-96, Standard Specification for Mortar Cement, and ASTM C1357-96, Standard Test Methods for Evaluating Bond Strength, and will be used in the inter-laboratory study. However, other test procedures must still be established. To do so, and prior to the inter-laboratory study, a pilot "ruggedness study" was conducted; the objective was to determine which additional factors should be controlled during the inter-laboratory study. In this paper, the conduct and results of that ruggedness study are presented and discussed in the light of current bond-wrench testing procedures, and specific changes are recommended to ASTM bond-wrench testing standards.

Book Synopsis Correlation of Strength of Cement Mortar Cured by 28-Day Standard and Accelerated Methods by : S. Chriss
Download or read book Correlation of Strength of Cement Mortar Cured by 28-Day Standard and Accelerated Methods written by S. Chriss and published by . This book was released on 1976 with total page 4 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on the results of an experimental preliminary investigation, two correlations are presented between the standard 28-day strengths of 2-in. (50.8-mm) portland cement mortar cube specimens and the strengths of companion specimens cured under standard conditions for 1 day, and then subjected to accelerated curing for 1, 2, and 3 days in a water bath at 95°C. The proposed correlations, although by no means conclusive, seem to indicate that a unified approach to prediction of standard 28-day strengths may be possible without resorting to development of individual "standard curing-accelerated curing" relationships for each kind of cement of different quality.
