Title: Linking New Australian Alkali Silica Reactivity Tests to World-Wide Performance Data
Author(s): Paul Rocker, James Mohammadi, Vute Sirivivatnanon, Warren South
Appears on pages(s): 502-513
Keywords: AMBT, ASR, CPT, ASR performance limits
Abstract:The long awaited Australian Standard test methods to detect alkali-silica reactivity (ASR) of aggregates - AS 1141.60.1 accelerated mortar bar test (AMBT) and AS 1141.60.2 concrete prism test (CPT) - were published in September 2014. Both test methods were adopted correspondently from the ASTM 1260 and ASTM C1294 test methods but with different performance limits leading to a new class of slowly reactive aggregates. This paper reviews international and Australian research which supported these new performance limits. It also reviews and examines the value of these testing methods in predicting the ASR of aggregates in field-exposed large concrete blocks and a limited number of concrete structures. The outcomes may lead to a consideration of the hierarchy of these two test methods.
