Abstract

This paper mentions the alkali reactivity determination and reactivity degree classification for concrete aggregates in view of the work conducted by RILEM 219-ACS Technical Committee of which the author is a member between the years 2007-2014. Thus, it is aimed to introduce national researchers the latest developments on the way to internationally accepted test and aggregate evaluation methods in order to raise their awareness and disseminate the results of the committee work. In light of the technical committee reports from the past to present, state of the art recommendations and test methodologies are described, their comparative evaluation as well as possible further research topics on this area are presented

BETON AGREGALARINDA ALKALİ REAKTİVİTE YATKINLIĞININ TESPİTİ İÇİN RILEM YAKLAŞIMI

Abstract

Bu çalışma, yazarın 2007-2014 yılları arasında üyesi bulunduğu RILEM 219-ACS Teknik Komitesi çalışmalarının çıktıları ışığında beton agregaları için betonda zararlı genleşmeler ve çatlamalara sebebiyet veren alkali reaktivitesi tespiti ve sınıflandırılmasını anlatmaktadır. Bu sayede, uluslararası kabul görmüş standartların ve agrega değerlendirme metodolojilerine giden yolda ülkemiz araştırmacılarına son gelişmeler aktarılarak RILEM yaklaşımının tanıtımı ve yaygınlaştırılması amaçlanmaktadır. Geçmişten günümüze alkali agrega reaktivitesi konusunda çalışmalar yapmış olan teknik komitelerin bilgileri ışığında, güncel öneri ve test metotları tanıtılmış, karşılaştırılmalı değerlendirmeleri gerçekleştirilerek geliştirilmeye açık konular vurgulanmıştır
