unit weight of aggregate

As for concrete itself, the density of concrete of normal weight is about 2,400 kg per cubic meter, or 145 lbs per cubic foot The concrete density varies depending on the amount and density of the aggregate, how much air is entrapped or purposely entrained, the cement concentration, and the maximum size of aggregate used...

Basic aggregate weight-volume relationships are important to understand aggregate structure and properti Fundamentally, aggregate volume properties are desired, but since mass measurements are typically much easier, masses are typically taken then converted to volume by using specific graviti The following is a brief discussion of the more important mass-volume relationships of aggregat...
