The processing includes proper burning and grinding of the materials under carefully controlled conditions to form the amorphous form of silica which is important to their pozzolanic activity. However, the types of cement have a significant effect on resistivity. Although most authors agree that these long, strikingly regular, cuspate-lobate structures formed during layer-parallel shortening, there is less agreement about the origin of the arrays of quartz veins, which are always present between individual mullions. We propose a two-phase development of these structures. There is developing concern all over the world about the raw materials assets utilized in the creation of concrete, and most of them are limited and exhaustible. Bleeding on probing was significantly more frequent on implants cemented with PIC (100% with and 94% without excess cement) than on implants cemented with TB (46%). It was found that w/b ratios have no significant influence on the electrical resistivity values of the concrete for a same type of cement. There are two types of pozzolana, natural and artificial.
