Cylindrical specimens of magnesium phosphate cement were molded and varying amounts (0 to 30% weight) of grinding dust were added to the ceramic matrices. The influence of the addition of grinding dust on the characteristics of the mortars in terms of microstructure (SEM), mechanical strength and capillary water absorption was verified.


Cement manufacturing - brief description of a cement mill. Cement clinker is usually ground using a ball mill. This is essentially a large rotating drum containing grinding media - normally steel balls. As the drum rotates, the motion of the balls crushes the clinker. The drum rotates approximately once every couple of seconds.

I. Introduction. In 1824, Joseph Aspdin received a patent 2 for what he called "portland cement," and thereby transformed the way modern infrastructure would be constructed to the present day. Various construction cements had been used, possibly for as many as ten thousand years 3.None of them, however, were destined to rival Aspdin's cement, which would become the ubiquitous fabric of ...

Cement manufacture is a three-stage process: raw material preparation, clinker production and clinker grinding with other components to produce cement. Different raw materials are mixed and milled into a homogeneous powder, from which clinker is produced in high-temperature kilns where direct emissions of CO 2 occur.
