Download or read book Improving Concrete Quality written by Karthikeyan H Obla and published by CRC Press. This book was released on 2014-06-25 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: Improve the Quality of Concrete, Improve the Quality of Construction Quality measurement is not prevalent in the concrete industry and quality investment is not seen as potentially generating a positive return. Improving Concrete Quality examines how and why concrete quality should be measured, and includes instruction on developing specifications with the aim of improving concrete quality. Reduce Concrete Variability: Reduce Costs and Increase Volume The first part of the book considers the tangible and intangible benefits of improved quality. The later chapters explore concrete strength variability in detail. It provides a greater grasp of the variation in concrete, as well as a deeper understanding of how material variability affects concrete performance. The author discusses the components of variability (material, manufacturing, testing) and provides steps to measuring and reducing variability to improve the quality of concrete. The text also contains a chapter on data analysis for quality monitoring and test results. Come Away with Practices and Tools That Can Be Applied Immediately: Provides techniques and how specifications can improve concrete quality Offers a clear understanding of the link between the materials (cement, SCM, aggregate, water, air), manufacturing, testing variability, and concrete quality Includes information on analyzing test data to improve quality Improving Concrete Quality quantifies the benefits of improved quality, and introduces novel ways of measuring concrete quality. This text is an ideal resource for quality personnel in the concrete industry. It also benefits architects, engineers, contractors, and researchers.

Book excerpt: This volume highlights the latest advances, innovations, and applications in the field of fibre-reinforced concrete (FRC), as presented by scientists and engineers at the RILEM-fib X International Symposium on Fibre Reinforced Concrete (BEFIB), held in Valencia, Spain, on September 20-22, 2021. It discusses a diverse range of topics concerning FRC: technological aspects, nanotechnologies related with FRC, mechanical properties, long-term properties, analytical and numerical models, structural design, codes and standards, quality control, case studies, Textile-Reinforced Concrete, Geopolymers and UHPFRC. After the symposium postponement in 2020, this new volume concludes the publication of the research works and knowledge of FRC in the frame of BEFIB from 2020 to 2021 with the successful celebration of the hybrid symposium BEFIB 2021. The contributions present traditional and new ideas that will open novel research directions and foster multidisciplinary collaboration between different specialists.

Book excerpt: The objective of this research is to establish the technical engineering and cost analysis concepts that will enable WisDOT management to objectively evaluate the feasibility of switching construction specification philosophies for aggregate base. In order to accomplish this goal, field and laboratory testing programs were conducted on existing HMA pavements and on base layers under construction as well as comprehensive survey was conducted on highway agencies practices pertaining to base layer construction in the U.S. and Canada. This research proposed construction specifications for aggregate base course layers.
Download or read book RILEM Recommendations for the Prevention of Damage by Alkali Aggregate Reactions in New Concrete Structures written by Philip J. Nixon and published by Springer. This book was released on 2015-09-30 with total page 181 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains the full set of RILEM Recommendations which have been produced to enable engineers, specifiers and testing houses to design and produce concrete which will not suffer damage arising from alkali reactions in the concrete. There are five recommended test methods for aggregates (designated AAR-1 to AAR-5), and an overall recommendation which describes how these should be used to enable a comprehensive aggregate assessment (AAR-0). Additionally, there are two Recommended International Specifications for concrete (AAR-7.1 & 7.2) and a Preliminary International Specification for dams and other hydro structures (AAR-7.3), which describe how the aggregate assessment can be combined with other measures in the design of the concrete to produce a concrete with a minimised risk of developing damage from alkali-aggregate reactions.

Download or read book Automated Laboratory Testing Methods for Specific Gravity and Absorption Verified to Match the Current Method Results written by Arudi Rajagopal and published by . This book was released on 2009 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: Twenty six coarse aggregate (12 gravel, 10 lime stone, 4 slag) and nine fine aggregate (4 lime stone, 3 natural sand, 2 slag sand) materials were collected from various sources in Ohio. Specific gravity and water absorption of the coarse aggregate samples were determined using CoreLok and ASTM C 127 procedures while testing of fine aggregate samples involved CoreLok, SSDetect and ASTM C 128 procedures. All the tests were performed in a single laboratory and by the same technician. The primary intent of the study was to investigate the ability of CoreLok and SSDetect to obtain faster results while, at the same time, improving the accuracy of results. The results led to the following conclusions: Coarse Aggregates: CoreLok bulk specific gravity (Gsb) values are up to 8% higher than the ASTM C 127 Gsb values. The difference between the corresponding apparent specific gravity (Gsa) values vary from 0 to 12%. The CoreLok absorption values are 1 to 81% lower except for two slag samples. These differences are statistically significant at 95% confidence interval. Fine Aggregates: The SSDetect Gsb results closely follow the ASTM C 128 values. CoreLok Gsb values are moderately higher than ASTM and SSDetect for natural sand, but lower for slag. Gsa results of all the three test procedures follow each other closely. These differences are not statistically significant. The difference in absorption values between CoreLok and ASTM C 128 procedure ranges from 1.5% to 243.7%. In case of SSDetect vs. ASTM, this difference is 0.9% to 124.2%. An in-depth absorption study of coarse aggregates using CoreLok highlighted some inconsistencies in the procedure. The principal recommendation of the study for the Ohio Department of Transportation is to continue specific gravity and absorption tests of coarse and fine aggregates using the traditional ASTM procedures.
