Alkali – Silica Reaction emerges through alkali in the cement, active silica and moisture in the aggregate. Active silica, alkali and moisture reacts together and than they emerge into a jell form which is a compound of alkali and silica. These compound swell in the concrete and starts cracking the concrete. Alkali – silica reaction is a long continuous process and there is no remedy when once the cracks in cement starts. The remedies must be undertaken at the design stage of the concrete.
ASR Test Cabin contains the samples in an environment of %100 relative moisture
between 20° C – 70° C with the accuracy of 0.5K .
Temperture is saved continuously and displayed as a graphic.
ASR Sample Pot made out of 2 mm thick stainless steel and internal size is 280 x 130 x 400
