Alkali Silica Reaction Bath
Product Overview
Alkali Reactivity Reaction Container is used for the chemical determination of the potential reactivity of aggregates with alkalis in Portland cement concrete in accordance with ASTM C289, UNI 8520-22, NF P94-048 standards.
Technical Specifications
Standards Compliance :
- Complied as per CANADA CSA-A23.2-25A
Application :
- Alkali-Silica Reaction Bath is used to keep 25 25 285 mm concrete samples in NaOH (sodium hydroxide) at a specified temperature.
Temperature Control :
- The temperature can be adjusted from ambient to 100 C using a digital thermostat with 1 C accuracy.
- Temperature can also be monitored by an external thermometer.
Construction :
- The bath is completely made of stainless steel and has a glass cover.
Sample Placement :
- Samples are placed on a special rack where each sample stays independent from each other in a vertical position.
Safety & Monitoring :
- The bath is also equipped with an electronic water level indicator which gives an alarm when the water level is lower than required.
- The device 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.
Additional Use :
- By removing the special rack, Aggregate Reaction Bath can also be used as a general-purpose water bath.
Ordering Information :
- Alkali Reactivity Reaction Container, Alkali Specimens Can, Length Comparator, Analog or Digital Dial Gauge or Heidenhain Digital Readout Unit with 30 0.0001 mm Length Measuring Sensor, Two-Gang Prism Shrinkage Mould, Steel Inserts and Reference Rod should be ordered separately.
