The special plates illustrate Venetian Terrazzo and Rustic Terrazzo, and are not covered under the Standard plate classification. Palladiana and Venetian Terrazzo are considered to be a highly decorative form of Terrazzo and are eminently suitable for high traffic areas. Palladiana and Venetian Terrazzo normally have Portland cement as a matrix. Rustic Terrazzo is a safe, non-slip, cementitious surfacing suitable for outdoor paving. The texture varies in accordance with the chip sizes and with a great variety of suitable hard, colorful aggregates.

The main characteristics of these special plates are as follows:

• PALLADIANA
  A form of Terrazzo in which 1/2 inch thick random fractured slabs of marble are set in an underbed and the joints between these slabs are filled with Terrazzo, or a low shrinkage white or tinted jointing material.
  
  
• VENETIAN TERRAZZO
  Same as standard Terrazzo, except that large chip sizes [#3 through #8] are utilized. Venetian Terrazzo, therefore, requires an increased thickness to accommodate the larger chip sizes.
  
  
• RUSTIC TERRAZZO
  A form of Terrazzo in which no grinding is required. Instead, the topping is washed or treated in such a way that the chips are exposed, creating a uniform textured surface. In exterior work where the Rustic Terrazzo will be exposed to freezing conditions, it is recommended that a dense chip be used, and that the matrix contain a suitable air-entraining agent.
