Sulphate Content Test
The Sulphate Content Test determines the presence of sulphates in aggregates using protocols such as ASTM C1580 or BS 812-118. Excessive sulphates can trigger chemical interactions with cement hydration products, resulting in expansive compounds such as ettringite, which can cause cracking, expansion, and a loss of concrete strength. This test is especially important when aggregates are made from recycled, industrial, or marine materials. Knowing the sulfate content enables engineers to choose suitable mix designs, cement types, and mitigation techniques. It is a critical protection when building long-lasting infrastructure exposed to damp or chemically harsh conditions.

Advantages of Sulphate Content Test:

• Identifies potentially dangerous sulfate levels.
• Prevents extensive chemical reactions in concrete.
• Provides compatibility with cementitious materials.
• Prevents long-term structural deterioration.
• Essential for aggressive and sulfur-prone conditions.
