Explain dry and wet process of cement manufacturing

The flowsheet diagram of the wet process for manufacturing Portland cement is given in Figure 3.3. The limestone is disintegrated in crushers. The crushed limestone is fed to a tube mill, where the limestone and the clay, introduced as a slurry from a clay mixer, are simultaneously subjected to fine grinding.

Effect of Using Micropalm Oil Fuel Ash as Partial …

This study investigates the effects of micropalm oil fuel ash (mPOFA) on compressive strength and pore structure of cement mortar. Various experimental techniques, such as compression test, isothermal calorimetry, mercury intrusion porosimetry, and X-ray diffraction, are performed to figure out the effect of using mPOFA as partial replacement of cement on the hydration of cement and determine ...
