HOW GREEN ISLAND CEMENT IS MADE

Green Island Cement is manufactured from hard limestone and clay. It is necessary that these materials should be finely ground in order that they may come into intimate contact with one another in the burning process.

The finely pulverised materials are mixed in a certain definite proportion, roughly one part of clay, to three of limestone, and are fed to the Rotary Kilns.

In these kilns they meet the hot gases and flames generated by pulverised coal blown in at the other end of the kilns, and after various chemical actions have taken place, they combine to form Portland Cement Clinker.

The Clinkeris ground down with a small percentage of gypsum to regulate the setting time, and Green Island Portland Cement is thus produced.

Although sounding so simple, in reality the process is an intricate combination of mechanical, physical and chemical operations, needing great skill and care.

Nothing but constant and accurate supervision will yield the results so well-known with Green Island Cement, namely, strength, uniformity and reliability.

This Journal seems to be greatly appreciated not only by our own students, past and present, but by engineers generally in China. It is a matter for regret that it is not possible at present to publish more often than once a year.

In 1831 there occurred the death of William Symington, probably the greatest pioneer in marine engineer- ing.
