La description
Portland cement (often referred to as OPC, from Ordinary Portland
Cement) is the most common type of cement in general use around the
world because it is a basic ingredient of concrete, mortar, stucco
and most non-specialty grout. It usually originates from limestone.
It is a fine powder produced by grinding Portland cement (more than
*0%), a limited amount of calcium sulfate (which controls the set
time) and up to 5% minor constituents as allowed by various
standards such as the European Standard.
In order to achieve the desired setting qualities in the finished
product, a quantity (**8%, but typically 5%) of calcium sulfate
(usually gypsum or anhydrite) is added to the clinker and the
mixture is finely ground to form the finished cement powder. This
is achieved in a cement mill. The grinding process is controlled to
obtain a powder with a broad particle size range, in which
typically *5% by mass consists of particles below 5 μm diameter,
and 5% of particles above *5 μm. The measure of fineness usually
used is the "specific surface area", which is the total particle
surface area of a unit mass of cement. The rate of initial reaction
(up to *4 hours) of the cement on addition of water is directly
proportional to the specific surface area. Typical values are
*****0 m2·kg−1 for general purpose cements, and *****0
m2·kg−1 for "rapid hardening" cements.
