Carrara marble

A series of slurries of high solids, dispersed ground calcium carbonate were prepared. Firstly, a sample of Carrara marble was ground without dispersant to a mean size of 0.5 fim. This was then filtered to a solids level of 76% (volume fraction 46%), before being thoroughly mixed with the required dose of sodium polyacrylate dispersant and adjusted to a constant solids level of 70%. Doses ranged from zero to 25mgg (2.5%) of calcium carbonate. Samples were then left for two days to reach a steady-state adsorption level. After this they were sheared and their viscosity (Brookfield RV, 100 rpm, spindle 3) was measured. 

Prepared by igniting carefully picked Carrara marble in a crucible and hydrating with distilled water.

Marble is a type of recrystallized limestone. The recrystallization process probably occurred about 2000 million years ago in connection with volcanic activity. The carbonates were heated to a high temperature and simultaneously at such a high pressure that decomposition was avoided. Under these circumstances calcite and dolomite were recrystallized to marble. Marble is a fine-grained rock, although the grains may be very small, almost invisible, as in statuario, the completely white Carrara marble. The white semi-transparent Greek marble from the island of Paros was the material for many famous statues.
