Silo Construction in Nebraska 



At present there is nobody in the state of Nebraska manu- 

 facturing especially burned clay blocks for silos of this nature. 

 The common block must be plastered on the inside and outside 

 to make it permanent or blocks which are hard burned and do 

 not need to be plastered inside and out as common blocks do 

 must be ordered from other states. 



The choice between this silo and the concrete block silo lies 

 largely in the freight rates and in the price for clay blocks, sand, 

 and cement. 



COST OF CLAY BLOCK SILOS. 



SOLID CONCRETE SILOS. 



During the past summer, the Department of Agricultural 

 Engineering has supervised the erection of four solid concrete 

 silos. Three of these were erected with a form made by the 

 Department, while one was erected with a form that was made 

 on the ground where the silo was built. 



These silos require the same type of foundation that the con- 

 crete block silos do, and should have a concrete roof, and it is 

 also well to have a concrete chute, as it costs very little more 

 than a good frame chute. 



FORMS. 



The forms for erecting the walls are preferably made by 

 building up an inside framework of wood which is covered with 

 one-inch material. If the forms are to be used on more than one 

 silo, they should be covered with galvanized iron. 



The wood forms are erected in four sections and held together 

 with bolted cleats which permit the form to shrink up so that it 

 can be taken away from the concrete when desired and then 

 raised. 



The outside form is made of a heavier grade of galvanized 

 iron and riveted together into either two or four sections as de- 

 sired. These sections are held together by means of bolts, which 

 permit them to draw up or expand.
