EXAMPLE 2.6.1. ESTIMATING CONCRETE PAVEMENT USING THE WEIGHT METHOD

Estimate the concrete materials (class B) for a pavement 4 inches thick, 10m width, and 1-km long using weight method


For weight method, density of each component should be known.

Volume of pavement:

           

Convert this volume into dry volume:

           

With class B, the proportionality is 1:2.5:5.

        
   
 To find the weight, multiply the density of cement =   .

         

For sand: 
      
          

For sand, density is .

         


For gravel:

         

         

         

Using  as density of gravel:
