Page 42 - Type 1 includes cement produced from a mixture of argillaceous limestone ("cement rock") and pure limestone. This is the combination of materials used in all the cement plants of the Lehigh district of Pennsylvania and New Jersey, and...
Page 49 - These attempts were not commercially successful, and although their failure was not due to any defects in the limestone used, a certain prejudice arose against the use of the hard limestones. In recent years, however, this has disappeared, and a very large proportion of the American output is now made from mixtures of limestone with clay or shale.

Page 59 - The raw material must be increased if it carries any appreciable amount of water. Clays will frequently contain 15 per cent or more of water; while soft chalky limestones, if quarried during wet weather, may carry over 20 per cent.
Page 52 - States, except in areas which have been glaciated, since they are in general due to the damming of streams by glacial material. Workable marl deposits, therefore, are confined almost exclusively to those portions of the United States and Canada lying north of the southern limit of the glaciers. Marl beds are found in the New England States, where they are occasionally of important size, and in New York, where large beds occur in the.
Page 197 - Savage River, and farther south by Little Savage River, Swamp Run, and Pine Swamp Run. Along the northern end of Backbone Mountain the line of outcrop is for a large part of the way up on the mountain side, but farther south it occupies a series of valleys like those along Savage Mountain, but less pronounced.
Page 59 - ... ways, the choice depending largely upon the manufacturing processes in use at the plant. At plants using dome or chamber kilns, or where the marl is to be dried before it is sent to the.
Page 63 - Adding it at this point insures much more thorough mixing and pulverizing than if the mixture were made later in the process. At some of the few plants which use plaster instead of gypsum the finely ground plaster is not added until the clinker has received its final grinding and is ready for storage or packing.
Page 43 - Deposition from solution by purely chemical means has undoubtedly given rise to numerous limestone deposits. When this deposition took place in caverns or in the open air it gave rise to onyx deposits and to the "'travertine marls" of certain localities in Ohio and elsewhere.
Page 78 - Hatchs bluffs. On Little Tombigbee River the same rock makes the celebrated bluffs at Bluffport and at Jones Bluff (Epes), beyond which for several miles it is shown along the stream. Judging from the width of its outcrop, this division of the Selma chalk must be about 300 feet in thickness. It underlies the most fertile and typical " prairie
