Abstract:

Alkaline silic reactivity (ASR) is a one-way complex reaction that significantly affects the resilience of concrete structures. In this study, the characteristics of the trakat and pomza aggregates located in the north of the Van Valley are studied in relation to the alkaline silic reactivity (ASR). The accelerated test on samples for the purpose of determining the ASR, chemical method experiments have been carried out. For the accelerated shell bar experiment, the shell bar was prepared 16 pieces, with weight of 10%, 20% and 30% pumping, respectively, instead of the tracket. According to the accelerated bar test, 3, 7, 14, 28 and 56 day size changes were measured. For the purpose of determining the ASR by chemical method, a sample of 25 gr 3 of the remaining material from the aggregates was taken from the 0.250 mm and the 0.125 mm range of elephants. SEM analyses were made on samples in order to see the differences between the pre- and post-experimental samples. Certain differences have been observed in the SEM images obtained before and after the accelerated bar.
