7 On the other hand, the cost of grinding (บด) to a higher fineness is considerable, and also the finer the cement, the more rapidly it deteriorates (เส อมลง) on exposure to the atmosphere. Finer cement leads to a stronger reaction with alkali-reactive aggregate (มวลรวม), and makes a paste, though not necessarily concrete, exhibiting a higher shrinkage and a greater

Although the process for cement manufacture is relatively similar across North America and much of the globe, the reference to cement specifications can be different depending on the jurisdiction. In addition, test methods can vary as well, so that compressive strength requirements (for example) in Europe don't 'translate' directly to those in North America.
