Sulphate resistance
Sulphate resistance is frequently the subject of cement chemistry-related questions. Why do we need to resist sulphate and where? Is there a downside to sulphate-resistant clinker?
Bridge piers in estuaries require a cement that is resistant to sulphate attack
Sulphate is an essential component of Portland cement but, as with all good things, it must be taken in moderation. Excessive sulphate can lead to catastrophic failure of concrete while a shortage can mean that the concrete cannot be placed.
