CONSTRUCTION MATERIALS & TESTING

Coarse aggregate is placed in a rigid bucket and rodded with a tamping rod to determine its unit weight. The following data are obtained:

 Volume of bucket = 0.4 cuft

 Weight of empty bucket is 18.3 lb

 Weight of bucket filled with dry rodded coarse aggregate = 56.9 lb

 

Calculate the dry-rodded unit weight in lb/ft^3 (one decimal only).

    3. No-fines conerete, made from a uniformly graded coarse aggregate and a cement-water paste, is beneficial in areas prone to excessive rainfall because of its excellent drainage properties. The article "Pavement Thickness for No-Fines Concrete Parking Lots" (J. of Transportation Engr., 1995: 476-484) evaluated the relationship between Y = porosity (%) and X unit weight (lb/ft) in concrete specimens. Summary data resulting from the study is provided below - - = -471.5 lb/ft2-% n 15 =1640.1 lb/ft SK6.1 lb/ft i=1...
