This book was released on 1984 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: Three generations of the procedure were considered: Generation I: the original Kelly-Vail (KV) method developed by R.T. Kelly and J.W. Vail of the Greater London Council. Generation II: the CERL/KV method, developed by the U.S. Army Construction Engineering Research Laboratory (CERL). Generation III: the Corps of Engineers Concrete Quality Monitor (CE/CQM), also developed by CERL. The abilities of Generation II and III methods to help predict cement and water contents of a variety of concrete mixtures were determined in an extensive series of side-by-side laboratory tests. The tests evaluated the effects of sampling techniques and aggregate type. Variance techniques were analyzed to help establish accuracy statements and to compare the two methods and the utility of these methods as bases for predicting concrete compressive and flexure strength was assessed. Also, field and additional laboratory tests of the Generation III method were conducted to determine (1) how the Generation III method performed under field conditions and (2) the effects of selected common admixtures on the output of the chloride meter used in the Generation III method. The results demonstrated that the accuracies of Generations II and III were equivalent for identical test conditions and that aggregate characteristics affect the results of both cement content tests and both water content tests. It was also determined that actual water/cement ratios and water/cement ratios predicted on the bases of these methods may be used with equal accuracy for estimating 28-day concrete strength.

Download or read book Rapid Test Methods for Field Control of Highway Construction written by John D. Antrim and published by National Academy Press. This book was released on 1970 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research was conducted to determine the state of the art in the development, need, and use of rapid test methods. The first phase comprises a literature survey of current practices in quality control and acceptance testing, along with a study using statistical methods to assess the time limits for rapid tests. The second phase is concerned with the development and evaluation of new rapid test methods or principles to select those worthy of further investigation. thirty-eight state highway departments participated in the study, and interviews were conducted when appropriate. The second phase of the study applied to rapid test methods for asphalt content determination, compaction control, gradation of several types of aggregate, density of base course materials and soils, and moisture content. The results of all tests are appended.

Available in PDF, EPUB and Kindle. Book excerpt: Presented in this paper are results of a program to evaluate procedures for the rapid determination of both cement and water contents of fresh concrete. Three generations of a general method were considered. The abilities of the current (Generation II-Construction Engineering Research Laboratory/Kelly Vail [CERL/KV]) and recently evolved (Generation III-Construction Engineering Research Laboratory/Concrete Quality Monitor [CERL/CQM]) procedures to aid in predicting cement and water contents of a variety of concrete mixtures were determined in an extensive series of side-by-side laboratory tests. Evaluated in the tests were effects of sampling techniques and aggregate type. Analysis of variance techniques were used as aids in establishing accuracy statements and comparing the two procedures. Results demonstrated that accuracies of the CERL/KV and CERL/CQM methods were equivalent for identical test conditions. Further, it was determined that aggregate characteristics affect results of both cement-content tests and both water-content tests.
