Reinforced Concrete Field Handbook 



Construction Data for Office and Work 



This book is published in response to a demand for the latest 

 experience in field work put into few words for pocket use, 

 eliminating all but essentials. The subject matter following is laid 

 out and grouped under three main heads. 



MATERIALS OF CONSTRUCTION Concrete. 



Cement. 

 Sand. 

 Aggregate. 

 Steel (Material.) 

 METHODS OF CONSTRUCTION Centering (Assembling and 



Dissembling.) 

 Steel (Fabrication, and 



placing.) 

 Manufacture of Concrete. 



CONSTRUCTION ORGANIZATION AND FIELD NOTES 



CEMENT. 



Cement as it is received on the work, is well known 

 as a fine, almost impalpable grayish powder. The one 

 necessity, which on construction work becomes almost 

 second nature, is to "keep the cement dry" in handling 

 and storing. 



Portland Cement is an artificial mixture in certain 

 well defined proportions established by practice, of lime, 

 silica, alumina and other substances in minor quanti- 

 ties. Lime, mixed and calcined with clay, has the 

 property of setting under water. A natural cement is 

 made from rocky conglomerates which may contain 

 the approximate quantities required, and which varies 

 in its properties as the constituents of the natural de- 

 posits vary in proportion. Portland cement on the 

 other hand is an exact artificial composition in pro- 

 portions determined by analysis and experiment.
