Ceramic tests of Illinois clays and shales, By William Arthur. White and joint author. J. E. (John Everts) Lamar Topics: Shale., Clay. The differential thermal method, by determining the thermal reactions undergone by a clay or shale, is a rapid means of identifying the mineral components of such materials, and because the properties of clays and shales depend largely on their mineral composition, it is at the same time a rapid method of evaluating the properties of such by: Enter the password to open this PDF file: Cancel OK. File name: . Clay and shale are used to manufacture bricks, ceramic tiles, and light-weight aggregate, an essential element for large building structures. Clay and shale are also important ingredients in the production of portland cement, a key binding agent used in concrete. The mica-like clay mineral illite was named for the state of Illinois.

Most ceramic products are clay-based and are made from a single clay or one or more clays mixed with mineral modifiers such as quartz and feldspar. The types of commercial clays used for ceramics are primarily kaolin and ball clay. Process Description1, For North Sea shales Horsrud et al. () recorded clay contents ranging from 32 to 82%, whilst for shales from Mexico and Brazil, Diaz-Perez et al. found clay contents ranging from ∼17 to 66%. Clearly such variations in texture could have a significant impact on shale reactivity whatever the clay mineral composition of the rock.

Expanded Clay, Shale and Slate. Clay bricks are produced by the drying and firing of clay or shale raw material, forming a sintered porous structure. Similarly, the drying and sintering of pelletised clay or shale can produce a usable aggregate, but more especially if the raw material is capable of being ‘bloated’. Lab Manager: Dr. Virginia McLemore Clay Material Testing. The NMBGMR has facilities to characterize the mineralogy and ceramic properties of clay materials. Testing capabilities include particle-size distribution analyses to measure the amounts of clay, silt and coarser material present; X-ray diffraction analyses to determine the mineralogy of both bulk-rock samples and clay-size material. Plainsman Clays has mined a wide range of its own clay materials since and has a very practical set of inexpensive tests to characterize them. My work there inspired the development and refinement of these tests and the creation of and the Digitalfire Reference Library. COVID Resources.
