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 petrograp | | 出版日期 | Book 2016 | | 關(guān)鍵詞 | Aggregates; Alkali-Aggregate Reactivity; Concrete and Rock; Concrete damage; RILEM; Thin-section petrogra | | 版次 | 1 | | doi | https://doi.org/10.1007/978-94-017-7383-6 | | isbn_softcover | 978-94-024-1339-7 | | isbn_ebook | 978-94-017-7383-6 | | copyright | RILEM 2016 |
