This book was released on 1981 with total page 25 pages. Available in PDF, EPUB and Kindle. Book excerpt: Evaluated was an approach to controlling the consolidation of in-place portland cement concrete on the basis of densities obtained with a Troxler 3411 nuclear gage. The gage was used in the backscatter mode on low-slump concrete bridge deck overlays and in both the backscatter and the direct transmission modes on continuously reinforced concrete pavements. The nuclear gage readings were compared to rodded unit weight determinations by ASTM C138. It was found that the nuclear readings compared favorably with the unit weight values. However, a petrographic examination of the cores taken from the deck and pavement indicated the presence of coarse voids in amounts exceeding those found in adequately consolidated concretes. It is concluded that the variability in density resulting from acceptable variations in the grading and amounts of individual ingredients of concrete, including the air content, is of the same order of magnitude or greater than the variability resulting from small but detrimental amounts of large air voids. Consequently, matching nuclear densities with densities obtained by weight per volume measurements does not assure the absence of small but detrimental excesses of large voids. However, the presence of an appreciable amount of honeycombing or excessive air entrainment would be detected by nuclear density measurements.

Available in PDF, EPUB and Kindle. Book excerpt: A study was made of the influence of consolidation on properties of portland cement concrete. A model acceptance sampling plan for concrete consolidation is proposed. The plan is of the inspection by variables type and requires a sample size of eight per lot. The plan provides for buyer's and seller's risks of 5 percent. The plan was field tested in Idaho and Iowa. Field testing indicated that monitoring concrete pavement consolidation is practical and economically feasible.

Download or read book Study of Nuclear Density Gauge for Compaction Measure written by Tripathi Bishnukumar and published by LAP Lambert Academic Publishing. This book was released on 2015-08-04 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book deals about applications of Nuclear Density Gauge tool and also significant comparison with conventional method such as a sand replacement method, core cutter and LWD for compaction measure. It is helpful for site engineer as well as students; whom are researching in Pavement field and Geo-technical field and also for contractor for rapid QA/QC work. To measure in-situ densities is a time consuming job, Nuclear Density Gauge tool measure within minutes and also evaluate moisture content. Nuclear Density Gauge tool significantly correlate with convention method, therefore it is recommended for QA/ QC work. This book helps researchers as well as student and site engineers.
