Book Synopsis In-Place Estimation of Concrete Compressive Strength Using Postinstalled Pullout Test - A Case Study by : Zhengqi Li
Download or read book In-Place Estimation of Concrete Compressive Strength Using Postinstalled Pullout Test - A Case Study written by Zhengqi Li and published by . This book was released on 2020 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: It was proposed that a 16-story steel framing structure be built on top of an existing 12-year-old 1-story reinforced-concrete structure. The in-place concrete compressive strength of 3 footings and 29 plinths was estimated using a postinstalled pullout test and a core compressive strength test. The influence of different length-to-diameter ratios of the cores and different diameters of cores and the correlation between maximum pullout force and core compressive strength were investigated. The results of the pullout test and core strength test indicate that the concrete compressive strength of footings and plinths was considered structurally adequate as per the acceptance criteria for tested core strength and estimated core strength given by ACI 318, Building Code Requirements for Structural Concrete and Commentary , and ACI 228.1R, In-Place Methods to Estimate Concrete Strength , respectively. Maximum pullout force had a strong correlation with the core compressive strength. The influence of the different length-to-diameter ratio of cores on the strength correlation was not significant if the raw results of the compressive strength tests were corrected by multiplying the corresponding correction factors for the length-to-diameter ratio given by ASTM C42, Standard Test Method for Obtaining and Testing Drilled Cores and Sawed Beams of Concrete . The mixed use of the test results of 3.20 and 3.74-in. (81-mm and 95-mm) cores resulted in a decrease in the R 2 of the correlation model, compared to that of the correlation model based on 3.74-in. (95-mm) cores. This was attributed to the potentially increased testing error as the diameter of the cores decreased. Recommendations for successfully performing postinstalled pullout tests in the field were proposed. With the use of pullout tests, the project team was able to determine that the existing structural members had sufficient capacity. A delay in the project schedule was avoided.

Available in PDF, EPUB and Kindle. Book excerpt: Why Buy This Book? Because the content in this book may prevent you from wasting hours of your life and possibly thousands of dollars due to misunderstanding concrete reports and submittals. The concrete industry has a variety of concrete reports. If not careful, these reports can waste a significant amount of time, energy, and possibly money. This book provides clear, concise, and practical information about different concrete reports such as the core report, the cement mill certification report, and the petrographer's report.

Book Synopsis Non-Destructive In Situ Strength Assessment of Concrete by : Denys Breysse
Download or read book Non-Destructive In Situ Strength Assessment of Concrete written by Denys Breysse and published by Springer Nature. This book was released on 2021-04-27 with total page 397 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book presents the work of the RILEM Technical Committee 249-ISC. Addressing the effective application of new recommendations for non-destructive in situ strength assessment of concrete, it provides information about the different steps of the investigation and processing of test results, until the delivery of strength estimates, and includes tables giving the minimum required number of cores in a variety of situations as well as several examples of how the recommendations can be used in practice. The book explores a topic which is of major importance, i.e. the assessment of concrete compressive strength in existing structures. This property (both mean and standard deviation) is a key input in many cases, such as the reinforcement of structures, the safety checking, the extension of service life. As the new RILEM recommendations imply a deep revision (and improvement) of field practice, the book is intended for managers of structures, structural engineers and specialists of NDT that have to answer these issues. More widely, it will benefit engineers and students who are interested in NDT and in the safety analysis of structures.
Book Synopsis ACI Manual of Concrete Inspection by :
Download or read book ACI Manual of Concrete Inspection written by and published by American Concrete Institute. This book was released on 2008 with total page 203 pages. Available in PDF, EPUB and Kindle. Book excerpt: This manual is intended to guide, assist, and instruct concrete inspectors and others engaged in concrete construction and testing, including field engineers, construction superintendents, supervisors, laboratory and field technicians, and workers. Designers may also find the manual to be a valuable reference by using the information to better adapt their designs to the realities of field construction. Because of the diverse possible uses of the manual and the varied backgrounds of the readers, it includes the reasoning behind the technical instructions. The field of concrete construction has expanded dramatically over the years to reflect the many advances that have taken place in the concrete industry. Although many of the fundamentals presented in previous editions of this manual remain relevant and technically correct, this eleventh edition incorporates new material to address these advances in technology

Book Synopsis Non-Destructive Evaluation of Reinforced Concrete Structures by : Christiane Maierhofer
Download or read book Non-Destructive Evaluation of Reinforced Concrete Structures written by Christiane Maierhofer and published by Elsevier. This book was released on 2010-06-04 with total page 265 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many concrete structures and elements of concrete infrastructure have exceeded their original design lives and are deteriorating to an extent where they are becoming dangerous. The deterioration can be internal or not obvious and therefore only shows up with detailed testing. Non-destructive evaluation of reinforced concrete structures, Volume 1: Deterioration processes and standard test methods reviews the processes of deterioration and classical and standard test methods.Part one discusses deterioration of reinforced concrete and testing problems with chapters on topics such as key issues in the non-destructive testing of concrete structures, when to use non-destructive testing of reinforced concrete structures, deterioration processes in reinforced concrete, modelling ageing and corrosion processes in reinforced concrete structures, components in concrete and their impact on quality, and predicting the service life of reinforced concrete structures. Part two reviews classical and standard testing methods including microscopic examination of deteriorated concrete, the analysis of solid components and their ratios in reinforced concrete structures, the determination of chlorides in concrete structures, and investigating the original water content of reinforced concrete structures.With its distinguished editors and international team of contributors, Non-destructive evaluation of reinforced concrete structures, Volume 1: Deterioration processes and standard test methods will be a standard reference for civil and structural engineers as well as those concerned with making decisions regarding the safety of reinforced concrete structures. - Provides a comprehensive discussion from examination of the components in concrete and their affect on quality through to the role of and tools required for lifetime management - Experts in the field identify the testing problems associated with infrastructure considering design, build and maintenance stages - Presents a guide for when to use non-destructive testing of reinforced concrete structures including the role of time in testing
