How many cement plants are producing in the USA?
In the spring of 1866, David O. Saylor, Esias Rehrig, and Adam Woolever started the Coplay Cement Company. The Coplay Cement Company was located along the west side of the Lehigh River and along side of the Lehigh Valley Railroad (L.V.R.R). Early in the 1870’s, Sailor began to experiment with the manufacturing of portland cement from rocks from his own quarry.
With this experimentation, Saylor discovered the possibility of making portland cement from raw materials at his disposal. He noticed that the harder burned portions of his Rosendale clinker produced cement that would show a tensile strength equal to that of the best imported portland cement, for a short period of time. However the cement had the problem of crumbling away with time. This problem was do to the raw materials not being properly proportioned.
Up until this experimentation, the trio of men manufactured natural rock cement. There were many other manufacturers of natural rock cement in the United States at this time. The Rosendale cement of New York had been on the market for over thirty years and manufacturers were already in operation on the Potomac, James, and Ohio River Valleys. Natural rock cements were made by driving off the carbonic acid from argillaceous (clay-bearing) limestones.
This was done at low temperatures in an ordinary upright kiln from 1,000 to 1,200 degrees Fahrenheit, and produced a soft yellow stone. This yellow stone was then ground into a powder and constituted the finished product. On the other hand, portland cement is an artificial mixture of raw materials, has a calcination at a temperature above 2,000 degrees Fahrenheit, and purer raw materials were used than necessary for natural cements.
