AGGREGATE SOUNDNESS TEST SET (Magnesium / Sodium Sulfate Soundness Test)

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.
