GRADATION OF AGGREGATE FOR CONCRETE BLOCK

The effect of grading of aggregate is shown in the bottom set of curves. From the curves it would appear that an optimum fineness modulus existed for each aggregate type and that there was a sharp decline in compressive strength when the fineness modulus was varied in either direction from this optimum valve for three of the four aggregates.
