Abstract:

Alkali silica reaction (ASR) in concrete is a deleterious reaction which occurs due to the reaction between alkalis in the pore solution and reactive forms of silica found in some aggregates. ASR results in expansion and cracking which reduce the mechanical properties of the concrete. An ultra-accelerated autoclave test method has been used to test concrete prisms with and without alkali boosting. In this method, expansion and deterioration caused by ASR in concrete was investigated using an autoclave to simulate long-term deterioration. Test parameters such as temperature, pressure, duration of autoclaving and alkali boosting were investigated. Results obtained within a short period, clearly show large expansions and deterioration levels for concrete made with reactive aggregates.
