Portland Cement Grades and Uses

Portland cement comes in several grades with different properties and uses. Its chemical composition and hydration behavior help determine how it performs in concrete. These differences matter in general construction, fast repairs, large structures, and places where sulfate exposure is a concern.

Consider a section of a busy highway that is damaged and requires urgent repair to minimize traffic disruption.

Such repair work uses rapid hardening cement, also known as Type III, as it develops its strength quickly.

While constructing large concrete sections, using cement with a high heat of hydration can lead to temperature dif...
