The Alkali Aggregate Reaction Bath is used to keep 25x25x285 mm samples in NaOH (Sodium Hydroxide) or in any other solution at a specified temperature. The temperature can be adjusted between ambient to 80°C by using the digital controller.

The chamber of the bath is made of stainless steel and has a a capacity of 27 specimens (25x25x285 mm).

UTA-0880 is supplied complete with 3 pcs. stainless steel alkali specimens cans (UTA-0882). Each can has a stainless steel hanger which can hold 3 pcs. 25x25x285 mm specimens. Additional alkali specimens cans should be ordered separately.

UTCM-0033 is used to determine the potential alkali reactivity of cement-aggregate combinations (mortar-bar method). This mould is also used for determining the length change of hardened cement paste, mortar and concrete.

The test also requires UTCM-0200 or UTCM-0210 or UTC-1170 Length Comparators.

UTA-0880 Aggregate Reaction Bath can also be used as a general purpose water bath.
