cement - cement - History of cement: The origin of hydraulic cements goes back to ancient Greece and Rome. The materials used were lime and a volcanic ash that slowly reacted with it in the presence of water to form a hard mass. This formed the cementing material of the Roman mortars and concretes of more than 2,000 years ago and of subsequent construction work in …

The magnesium slag is rich in Ca, Mg, Si elements, in which most of the arable land in China is deficient. Based on this, a new process for producing calcium-magnesium-sulfur-silicon(Ca-Mg-S-Si) fertilizer with magnesium slag is put forward by grinding and acid treatment. It is indicated from the trial production test that the optimum grinding diameter is about 60μm to producing …
