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 Petrographic Atlas: Characterisation of Aggregates Regarding Potential Reactivity to Alkalis written by Isabel Fernandes and published by Springer. This book was released on 2016-03-18 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: This RILEM AAR 1.2 Atlas is complementary to the petrographic method described in RILEM AAR 1.1. It is designed and intended to assist in the identification of alkali-reactive rock types in concrete aggregate by thin-section petrography. Additional issues include: • optical thin-section petrography conforming to RILEM AAR 1.1 is considered the prime assessment method for aggregate materials, being effective regarding cost and time. Unequivocal identification of minerals in very-fine grained rock types may however require use of supplementary methods. • the atlas adheres to internationally adopted schemes for rock classification and nomenclature, as recommended in AAR 1.1. Thus, rock types are classified as igneous, sedimentary or metamorphic based upon mineral content, microstructure and texture/fabric. • in addition, the atlas identifies known alkali-reactive silica types in each rock type presented. It also identifies consistent coincidence between certain lithologies and silica types; however, it refrains from attributing alkali-reactivity to a specific silica property or quality. • operator skill and experience remain essential for reliable assessment by thin-section petrography. • aggregate materials must be classified according to local criteria, based on regional experiences with ASR-damaged field structures and geology. Access to additional data may be relevant for the assessment of imported materials. • mere application of rock nomenclature does not provide any sort of warranty to the development of deleterious alkali-reaction. Such may result in either rejection of a suitable aggregate material, thus wasting a valuable resource, or acceptance of an unsuitable material leading to concrete damage, both of which are undesirable.

Download or read book Laboratory Tests of Concrete Aggregate and Riprap for New Lock and Dam Number 26 written by William O. Tynes and published by . This book was released on 1972 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ledge rock from three commercial sources was tested for suitability for use as riprap, and material from one of the sources of ledge rock plus crushed aggregate were also tested for use as concrete coarse aggregate. Drilled 6-in.-diameter cores from two commercial sources were tested for suitability for use as riprap and concrete coarse aggregate. A coarse sand and a blending sand were tested for use as concrete fine aggregate. Crushed aggregate manufactured from each of the two cores and one of the ledge rocks was tested in combination with blends of the coarse and fine sand for freezing and thawing of concrete aggregate. Results of the petrographic examination and tests on five sources of carbonate rock for riprap are reported. Consideration of the results of the freezing-and-thawing tests conducted according to CRD-C 144 on three sources of carbonate rock, for use in concrete indicate similarity. However, it appears that the material from one company is preferable to the other because it is thicker bedded. Material from a nearby quarry was previously used in the Alton Lock and Dam and it is known to be a reactive carbonate rock. Reaction rims have been observed in the Alton concrete. Considerations of field behavior of the Alton concrete and laboratory testing for length change of the Alton concrete show that this is not an expansive reaction and no precautionary measures are required for its use. Evaluation of rock from the Columbia Quarry and the Riverview Quarry for potential reactivity indicated that the Columbia rock was not reactive. However, some of the ledge 3 Riverview rock is potentially reactive.
