AGGREGATE SOUNDNESS TEST SET (Magnesium / Sodium Sulfate Soundness Test)
CODE : R042
The Aggregate Soundness Test Set is used to evaluate the resistance of aggregates to weathering by simulating the effects of freeze-thaw cycles through repeated immersion in magnesium or sodium sulfate solutions, followed by oven drying.
This test is critical for determining the suitability of aggregates for use in concrete, asphalt, and other construction materials, particularly in environments subject to severe weather conditions.
The testing procedure involves immersing aggregate samples in a saturated sulfate solution for a specified period, drying them to induce salt crystallization within the pores, and repeating this cycle multiple times to assess durability.
The apparatus includes a corrosion-resistant density basket, a hydrometer for monitoring solution concentration, and a sealed container to maintain solution integrity throughout the testing cycles.
Optional accessories that should be ordered separately, such as a water bath, are available to regulate solution temperature, ensuring consistent and accurate test conditions in compliance with international standards.
