The Edgar Plastic Kaolin (EPK) Company, reputedly the oldest continuous mining operation in Florida, was founded in 1892 by Charles S. Edgar. Until the 1870s, the Edgars were farmers in Middlesex County, N. J., near the town of Metuchen. After discovering clay on the farm, Charles S. Edgar with his two brothers, formed the Edgar Brothers Clay ...
The first calcined clay contained more metakaolin than the second one. In addition to ordinary Portland cement, four binders were analysed: two binary blends with 25% of cement substitution by the two calcined clays. Two ternary binders, composed of 30% of calcined clay and 15% of limestone filler, were also studied, using both calcined …
Clays containing about 40% kaolin or above give strengths comparable to plain Portland cement when used in LC 3-50 (50% clinker, 30% calcined clay, 15% limestone and 5% gypsum). Such clays are widely distributed and, as clay is often one of the raw materials for cement production, may even be available in existing quarries of …
WHAT IS KAOLIN? Kaolin or china clay is a commercial clay composed principally of the hydrated aluminosilicate clay mineral kaolinite. The commercial value of kaolin is based on the mineral's whiteness and its fine, controllable particle size. Particle size affects fluidity, strength, plasticity, colour, abrasiveness and ease of dispersion.

Kaolinite was the dominant clay mineral in the kaolin deposits and occurrences in Africa with smectite and illite in major quantities, as well as a number of non-clay minerals commonly present in kaolins. Major applications of the kaolins included ceramics, bricks, earthenware, coating, paint, and functional filler.
Step 1: Prepare the Pond. If your pond has water, drain it first. Let it dry for some days so that the soil reaches optimum moisture content. Then remove all debris from the pond bottom and fix any holes found. For both new and old pond, compact the pond bottom well. It will add extra benefit.
