calcareous raw material) and clay, mudstone or shale as the source of most of the silica and alumina. Finished cement is produced by finely grinding together around 95% cement clinker with 5% gypsum (or anhydrite) which helps to retard the setting time of the cement.
The other main strategy for achieving a bulkier or smoother sheet, opaque sheet using clay, has involved the use of composite-type fillers, such as scalenohedral PCC (Gill 1990; Bown 1996). Before the emergence of scalenohedral PCC as a major papermaking filler, calcined clay filled a similar niche in various paper products (Bauch 1992 ...
Figure 11.25-4 illustrates the process flow for fire clay processing. Mined fire clay first is transported to the processing plant and stockpiled. In some cases, the crude clay is weathered for 6 to 12 months, depending on the type of fire clay. Freezing and thawing break the material up, resulting in smaller particles and improved plasticity.
Step 2. Grind the clay soil into a fine powder or paste using large, fat stones as "grinding stones." This will assist in the bonding process. Some clay soil is already at the right consistency, but grinding will generally improve the end result of your brick building.
There are many types of pottery clay that can be used for a clay body or a specific composition of clay. Clay bodies are grouped into three categories: earthenware, stoneware, and porcelain. Each group represents different characteristics, such as workability, firing (or maturity) temperature, and porosity.
A good rule of thumb is the more yellow the clay looks the higher the alumina content. And the less likely it will shrink a lot when you dry and Fire.
