TESTS OP CEMENT MADE BY THE STATE ENGINEER 



DURING 1897-1900 



BY EDWIN C. ECKEL C.E. 



I am indebted to Mr Edward A. Bond, state engineer, and 

 Mr William Pierson Judson, deputy state engineer, for permis- 

 sion to use the data on cement tests, here briefly discussed. Mr 

 Russell S. Greenman has kindly aided me in many ways. My 

 thanks are also due to Mr Joseph Morje, of the New York state 

 museum, for aid in the preparation of both manuscript and proof. 



The series of cement tests tabulated and discussed were made 

 during 1897, 1898, 1899 and 1900, in the cement testing labora- 

 tory of the state engineer's office, Albany N. Y. They are of 

 value as they represent tests on various brands made during a 

 comparatively long period in one laboratory. The sequence of 

 the tests was interrupted only by one change of operators, and 

 by one change of testing machine, both of which occurred during 

 1900. Mr Charles M. Pepson was in charge of the cement test- 

 ing work from 1897 to July 1, 1900, when he was succeeded by 

 Mr Russell S. Greenman, who is in charge at the present date. 



As the cement samples were taken from barrels submitted for 

 use, the results are of interest as showing the average quality 

 of the various brands as shipped for use on actual work. The 

 cements tested were, in general, those submitted for use on the 

 canal improvements. A circular issued in 1899 by Mr Edward A. 

 Bond, state engineer, offered the use of this laboratory for the 

 testing of cements sent in by town and county officials, and some 

 of the cement tested during 1900 came in under this offer. A 

 number of samples have also been tested in this laboratory for 

 Mr George L. Heins, state architect.
