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 100°C by using the digital controller with 1°C accuracy.

Temperature can also be monitored by an external 1°C accuracy PT 100 sensor placed in the water. The bath is completely made of stainless steel and has glass cover and a chamber with a capacity of holding 36 samples. The chamber has a cover made of stainless steel.

Samples are placed on a special rack made of polyamide where each sample stays independent from each other in a vertical position. The bath is also equipped with an electronic water level indicator which gives an alarm when the water level is lower than required.

GEN0033 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 Digital Length Comparators. By removing the special rack, GEN0880 Aggregate Reaction Bath can also be used as a general purpose water bath.
