cement, but is also influenced by watercement ratio, fineness and curing temperature. As each one of these factors is increased, heat of hydration increases. For usual range of Portland cements, about onehalf of the total heat is liberated between 1 and 3 days, about threequarters in 7 days, and nearly 90 percent in 6 months.

We first discuss cement production and special nomenclature used by cement industrialists in expressing the composition of their cement products. We reveal different types of cement products, their compositions, properties, and typical uses. Wherever possible, we tend to give reasons as to why a particular cement type is more suitable for a given purpose than other types.

Cement Silo. Common Issue Coating in cement Silo. It happens due to storage of cement in silos at high temperature 70 o C, and improper water spray system in cement mill. Strategy to fix the issue Use cement coolers if cement temperature is higher than specified. Do not store cement for long time in silo.
