In some cases, a precast cylinder of concrete may be fitted in the core hole by using cement grout or epoxy resin. Minimum core diameter is usually 100 mm but 75 mm and 50mm diameters may be used in special cases. The number of 50 mm diameter cores must be three times the number of 100 mm diameter cores to get the same accuracy.

Cement Production - The Concrete PortalDeze pagina vertalen

Modern day cement is an unusual industrial product produced in huge quantities in special plants that can produce nothing else. It is produced by a combination of unusual unit operations involving mining, very fine scale blending of raw materials, very high temperature clinkering reactions, controlled cooling, grinding, blending, and finally shipping under controlled conditions.

Cement Grinding in Ball Mills and Vortex Layer .Deze pagina vertalen

The use of ball mills in cement grinding is due to several factors, among which are relatively simple design and high processing rate. However, these machines have certain limitations as well. It is known that only 2 to 20% of the energy is consumed by the grinding proper, while the rest is expanded on overcoming friction, on vibrations and is dissipated as heat.

Manufacturing of Portland Cement – Process and .Deze pagina vertalen

The manufacture of Portland cement is a complex process and done in the following steps: grinding the raw materials, mixing them in certain proportions depending upon their purity and composition, and burning them to sintering in a kiln at a temperature of about 1350 to 1500 ⁰C. During this process, these materials partially fuse to form nodular shaped clinker by broking of chemical bonds of ...
