a concrete mix by the sum of the absolute volumes of water and air in the mix. The cement-voids ratio may measure, in a general way, the relative quality of concrete. F. Gradation Index The gradation index is a numerical value assigned to each mix number and determines the relative amounts of fine and coarse aggregate in the mix. Experience and extensive testing have found that for maximum ...
FINISH a concrete mix. Concrete that is stiff or dry may be difficult to Handle, Place, Compact, and Finish and, if not constructed properly, will not be as strong or durable when finally hardened. A slump test can be used to measure the workability of concrete. See CHAPTER 3 Concrete Testing Workability is affected by: THE AMOUNT OF CEMENT PASTE
