Atlanta, Ga. July 22nd, 19C5 Carolina Portland Cement Company, Atlanta, Georgia, Gentlemen, - I send you herewith, three photographs of the Atlanta Terminal Passenger Station at Atlanta, Ga., that will show certain portions of the buildings that hav“ been executed in Perro-Concrete wherein, the ' ~ * - - t, ran( j 0 f cement was used. I congratulate you upon the manner in which the "Old Do- minion'' 1 brand has stood the tests imposed upon it by the varied con- struction done by this Company, covered by the work in question. We have gotten excellent results, and are more than pleased to add our testimony in favor of "Old Dominion" cement. The Perro-Concrete work in this station was done under contract with the Baltimore Perro-Concrete Company, of Baltimore, Maryland, and was designed and executed by Hr. P. Berne, who is now Chief Engineer, and General SuperintenJ ent, of the Southern Perro- Concrete Company, with headquarters at Atlanta Georgia. I hope you will find the photographs interesting and of service to you as advertising matter for your new catalogue. Yours very truly, Chief Engineer. 6 Detail of Tower on Atlanta Terminal Passenger Station, Built of Ferro Concrete, made of Old Dominion Portland Cement 7 PORTLAND CEMENTl Q “Midway,” Atlanta Terminal Passenger Station.

Adopted by the Association of American Portland Cement Manufacturers, June 16, 1904. Adopted by the American Railway Engineering and Main- tenance of Way Association, March 21, 1905. GENERAL OBSERVATIONS. 1 . These remarks have been prepared with a view o£ pointing out the pertinent features of the various requirements and the precautions to be observed in the interpretation of the results of the tests. 2. The Committee would suggest that the acceptance or rejec- tion under these specifications be based on tests made bv an expe- rienced person having the proper means for making the tests. SPECIFIC GRAVITY. Specific gravity is useful in detecting adulteration or under- burning. The results of tests of specific gravity are not necessarily conclusive as an indication of the quality of a cement, but when in combination with the results of other tests may afiford valuable indications. FINENESS. 4. The sieves should be kept thoroughly dry. TIME OF SETTING. 5. Great care should be exercised to maintain the test pieces under as uniform conditions as possible. A sudden change or wide range of temperature in the room in which the tests are made, a very dry or humid atmosphere, and other irregularities vitally affect the rate of setting. TENSILE STRENGTH. 6. Each consumer must fix the minimum requirements for tensile strength to suit his own conditions. They shall, however, be within the limits stated. CONSTANCY OF VOLUME. 7. The tests for constancy of volume are divided into two classes, the first normal, the second accelerated. The latter should he regarded as a precautionary test only, and not infallible. So many conditions enter into the making and interpreting of it that it should be used with extreme care. So 8. In making - the pats the greatest care should be exercised to avoid initial strains due to molding or to too rapid drying-out during the first twenty-four hours. The pats should be preserved under the most uniform conditions possible, and rapid changes of temperature should be avoided. 9. The failure to meet the requirements of the accelerated tests need not be sufficient cause for rejection. The cement may, however, be held for twenty-eight days, and a retest made at the end of that period. Failure to meet the requirements at this time should be considered sufficient cause for rejection, although in the present state of our knowledge it cannot be said that such failure necessarily indicates unsoundness, nor can the cement be consid- ered entirely satisfactory simply because it passes the tests. GENERAL CONDITIONS. 1 1. All cement shall be inspected. 2 2. Cement may be inspected either at the place of manu- 3 facture or on the work. 4 3. In order to allow ample time for inspecting and testing, 5 the cement should be stored in a suitable weather-tight building 6 having the floor properly blocked or raised from the ground. 7 4. The cement shall be stored in such a manner as to 8 permit easy access for proper inspection and identification of 9 each shipment. 10 5. Every facility shall be provided by the contractor and a 1 1 period of at least twelve days allowed for the inspection and 12 necessary tests. 13 6. Cement shall be delivered in suitable packages with the 14 brand and name of manufacturer plainly marked thereon. 1 5 7. A bag of cement shall contain 94 pounds of cement net. 16 Each barrel of Portland cement shall contain 4 bags, and each 17 barrel of natural cement shall contain 3 bags of the above net 18 weight. 19 8. Cement failing to meet the seven-day requirements may 20 be held awaiting the results of the twenty-eight day tests before 21 rejection. 22 9. All tests shall be made in accordance with the methods 23 proposed by the Committee on Uniform Tests of Cement of the 24 American Society of Civil Engineers, presented to the Society 25 January 21, 1903, and amended January 20, T904, with all 26 subsequent amendments thereto. 27 10. The acceptance or rejection shall be based on the fol- 28 lowing requirements : NATURAL CEMENT. 29 11. Definition. This term shall be applied to the finely 30 pulverized product resulting from the calcination of an argil- 31 laceous limestone at a temperature only sufficient to drive off 32 the carbonic acid gas. SPECIFIC GRAVITY. 33 12. The specific gravity of the cement thoroughly dried at 34 ioo° C., shall be not less than 2.8. FINENESS. 35 13.

Pats of neat cement about three inches in diameter, 52 one-half inch thick at centre, tapering to a thin edge, shall be 53 kept in moist air for a period of twenty-four hours. 54 (a) A pat is then kept in air at normal temperature. 55 ( b ) Another is kept in water maintained as near 70° F. as 56 practicable. * For example the minimum requirement for the twenty-four hour neat cement test should be some specified value within the limits of 50 and 100 pounds, and so on for each period stated. 82 57 ij- These pats are observed at intervals for at least 28 58 days, and, to satisfactorily pass the tests, should remain firm 59 and hard and show no Signs of distortion, checking, cracking 60 or disintegrating. PORTLAND CEMENT. 61 18. Definition. This term is applied to the finely pulver- 62 ized product resulting from the calcination to incipient fusion 63 of an intimate mixture of properly proportioned argillaceous 64 and calcareous materials, and to which no addition greater 65 than 2 > c /c has been made subsequent to calcination. SPECIFIC GRAVITY. 66 19. The specific gravity of the cement, thoroughly dried at 67 ioo° C, shall be not less than 3.10. FINENESS. 68 20. It shall leave by weight a residue of not more than 9> c / 0 69 on the No. 100, and not more than 25% on the No. 200 sieve. TIME OF SETTING. 70 21. It shall develop initial set in not less than thirty min- 71 utes, but must develop hard set in not less than one hour, nor 72 more than ten hours. TENSILE STRENGTH. 73 22.
