ContactAggregate gradation curves: (a) maximum density gradations for 37.5 and 4.75 mm sizes based on the Fuller relationship; (b) a uniform aggregate; (c) a gap-graded aggregate; (d) screenings.
ContactGrading of aggregates reduces the chances of segregation in concrete. The graduation curve is also used to estimate the type of soil. The graduation curve is used to calculate the coefficient of uniformity and coefficient of curvature. It helps to determine parameters like D30, D60, and D10 which can be used as design parameters.

ContactMar 08, 2019The grading or size distribution of aggregate is an important characteristic because it determines the paste requirement for workable concrete. The more these voids are filled, the less workable the concrete becomes, therefore, a compromise between workability and economy is necessary.
