Gray Cement

The most common cement is the so-called Portland cement. The name was invented by Joseph Aspdin in his patent in 1824. It refers to the lime stone (Portland stone) from the Isle of Portland, a peninsula at the English Channel. Gray cement is most commonly used for producing mortar and concrete and is one of the most important binders for building materials worldwide.

It’s the mixture

Gray cement meets different applications. In view of ecological and economic aspects, nowadays, Portland cement components are increasingly substituted by e.g. blast-furnace slags, puzzolana, fly ashes or lime stone powders. They influence the parameters of the cement e.g. workability, strength development and durability. Thus, the cement can be optimally tailored to the requirements on the construction site. And, there is more to it than that: Carbon dioxide emissions are reduced, too.
