Next, we made sure the excess cement was completely removed from the proximal aspect adjacent to the other central incisor preparation. Then, the adjacent restoration was seated on the preparation (without cement) to hold the correct position of the cemented unit during the gel set. (Note: Finger pressure was maintained on the incisal edges of the restorations.) It is important that the
The original process at the Ramla cement plant to produce cement from limestone, which is the base material of cement, was a socalled wet line process. The original wet line had a capacity of 1,800 TPD (Tons Per Day). The first new production line producing cement through a socalled dry line process was commissioned in 1994. This line has a capacity of 5,000 TPD and is very successful

Portland cement, the kind most often used in concrete, is made from a combination of a calcareous material (usually limestone) and of silica and alumina found as clay or shale. In lesser amounts, it can also contain iron oxide and magnesia. Aggregates, which comprise 75 percent of concrete by volume, improve the formation and flow of cement paste and enhance the structural performance of
