Abstract
Cement industry consumes annually around 5% of total industrial energy and results in about 8% of the total global carbon dioxide emissions. Therefore, there is a burgeoning interest in finding alternative binders with lower environmental impacts. Among several promising alternatives, alkali-activated materials (AAMs) are attractive for many researchers. However, there are many concerns about the suitability and accuracy of conventional testing methods for evaluating AAM performance. One of the common concrete degradation mechanism in Quebec is the alkali-silica reaction. Many tests are available for evaluating aggregate reactivity. However, the accelerated mortar bar test is being used extensively due to its short testing duration. Therefore, this paper provides a review of the history of the mortar bar test, highlighting concerns about its feasibility for testing AAM.
