Contact SupplierAlkali-Silica Reaction (ASR) is a reaction in concrete between the alkali hydroxides and certain types of aggregate. Expansion processes due to ASR are of high importance in regards on cracking formation and thus on durability of infrastructure. For ensuring durable construction accelerated testing at 60 °C
 In this test chamber concrete specimen are stored at a temperature between 20 C and 65 C at nearly 100% rel. Humidity for testing aggregate combinations using concrete prisms. The temperature is displayed.
ASR machine :
Stainless steel inside resistant to corrosion inner bath welded in protective gasPerfect insulation to ensure that the outside temperature does not exceed 30 C
Very small temperature deviation
