Georgia Kaolin As The China Clay Constituent In Floor And Wall Tile Bodies, Alfred Arthur Mitchell
Georgia Kaolin As The China Clay Constituent In Floor And Wall Tile Bodies, Alfred Arthur Mitchell
Bachelors Theses
"The replacement of the China Clay content in vitreous floor tile and porous wall tile bodies wholly by Georgia sedimentary kaolin would reduce the cost of these bodies being used in our floor and wall tile plants at present. This plastic kaolin is available in large quantities in the State of George, covering an area of about 7500 square miles. It is the intention of this work to substitute this American Clay for the more costly imported English China Clay now being used"--Introduction, page 1.
The Transmission Of Pressure In The Dry Pressing Of Typical Building Brick And Fire Brick Mixes As Affected By The Variation In Grog Size, Henry Rickel Herron
The Transmission Of Pressure In The Dry Pressing Of Typical Building Brick And Fire Brick Mixes As Affected By The Variation In Grog Size, Henry Rickel Herron
Bachelors Theses
"In the formation of dry pressed ware, the transmission of pressure is of vital importance to the quality and character of the finished product as regards the resistance to spalling, load at high temperatures, slag action, abrasion and other physical properties. Furthermore, the transmission of pressure is a limiting factor as regards the size and irregularity of shape of a product manufactured by the dry press process"--Introduction, page 1.
Size And Shape Of Clay Grains As Affected By Various Methods Of Grinding, Henry William Meyer
Size And Shape Of Clay Grains As Affected By Various Methods Of Grinding, Henry William Meyer
Bachelors Theses
"It is a common belief among those persons manufacturing dry pressed brick that the shape of grain of the clay used for this purpose would materially affect the physical properties of the resultant product. Some believe that clays, dry pan-ground, give a better product than clays disintegrated mechanically or passed through rolls. In some recent dry press investigations it was found that some milling methods gave an advantage over other methods, in the matter of pressure transmission. Due to this, a possible cause for the advantage was attributed to the shape of the grains resulting from the various methods of …
The Effect Of Small Amounts Of Chrome Ore On Dry Press Diaspore Refractories, Allen John Reid
The Effect Of Small Amounts Of Chrome Ore On Dry Press Diaspore Refractories, Allen John Reid
Bachelors Theses
"The term "Diaspore" as used in this paper will be used to mean the diaspore clay from which refractory bodies are made. The pure mineral Diaspore (Al₂O₃ . H₂O) has an Al₂O₃ content of 85%, while the best grades of diaspore clay run from 76% to 79% diaspore. Diaspore clay consists of a varying percentage of diaspore, ranging from 60% to 79%, and the remaining percentage as clay. The most objectionable impurities which occure sic in diaspore clay are alkalies. The chief source of diaspore is the central part of Missouri. It occurs in pot hole formations accompanied by "flint" …
The Commercial Value Of High Iron And High Alkalie Diaspore, William Lucius Mccracken
The Commercial Value Of High Iron And High Alkalie Diaspore, William Lucius Mccracken
Bachelors Theses
"In a recent survey of the refractory field particularly regarding high iron and high alkali diaspore it was suggested that perhaps some of these impure clays had the proper flux content to make them a body of stable volume in the initial firing operation. At present there is an apparant sic lack of information regarding the commercial value of these impure diaspores. One of the great problems in the use of diaspore refractories is the lack of stability of volume while in service subjected to severe heat treatments of varying degrees"--page 3.
The Effect Of Bentonite On The Transmission Of Pressure In Green Dry Press Blocks, Charles William Mccaw
The Effect Of Bentonite On The Transmission Of Pressure In Green Dry Press Blocks, Charles William Mccaw
Bachelors Theses
"The object in view in this work was to study the effect of the addition of bentonite on the pressure transmission of dry pressed ware, consisting of plastic fire clay. It was hoped that the bentonite would improve the transmission of the pressure to a noteable extent, forming a stronger, more evenly pressed block than has before been accounted for. This would facilitate the dry pressing of block that tended to crumble and disrupt from excessive pressure, allowing the ware to be pressed harder, and therefore making a more dense product"--Reasons For Investigation, page 4-5.
Pressure Transmission In Clays Affected By Time Of Pressure Application, Robert Edward Lee
Pressure Transmission In Clays Affected By Time Of Pressure Application, Robert Edward Lee
Bachelors Theses
"Experienced dry-press operators have long known that when they slow down their presses, to the proper speed they are able to exert more pressure on a wetter mix with out pressure cracks becoming apparent. When a clay mix is compressed in a dry-press there is a gradation of the pressure exerted, from the rams to the center, causing in some cases a soft centered brick. "Shelly brick", are undersirable sic because they do not have uniform physical properties through out. This weakens their structure, due to unequal stresses developed in drying and fireing sic. The defective structure of dry-pressed brick …
Disintegration Of Green Missouri Fire Clay Bodies At Low Temperatures, Wilbur Brooks Schofield
Disintegration Of Green Missouri Fire Clay Bodies At Low Temperatures, Wilbur Brooks Schofield
Bachelors Theses
"Several years ago in the Ceramics Lab. of the Missouri School of Mines some A. P. Green Ozark Clay test pieces were left in a drier for a period of about seven months at a constant temperature of 110C. At the end of this period it was noticed that these specimens had disintegrated and crumpled down to a powdered mass. The object of this experiment was to repeat the former test and see if the clay would disintegrate and if so why. We also wished to find if by drying at higher temperatures for a shorter length of time would …
The Transmission Of Pressure In The Dry Pressing Of Typical Building Brick And Fire Brick Mixes As Affected By The Variation In Grog Size, Stanley John Tompach
The Transmission Of Pressure In The Dry Pressing Of Typical Building Brick And Fire Brick Mixes As Affected By The Variation In Grog Size, Stanley John Tompach
Bachelors Theses
"In the formation of dry pressed ware, the transmission of pressure is of vital importance to the quality and character of the finished product as regards the resistance to spalling, load at high temperatures, slag action, abrasion and other physical properties. Furthermore, the transmission of pressure is a limiting factor as regards the size and irregularity of shape of a product manufactured by the dry press process. Prior to the time of this investigation several companies have succeeded in producing ware up to six (6) inches in depth; but an increase over six inches has resulted, in every case, in …
