Properties of concrete aggregates The Concrete Portal

Aggregates that predominantly show size fractions in a limited range of sizes (such as the 20 mm and 10 mm aggregate in Figure 1) are called ‘uniformly’ graded, while aggregates that show a continuous gradation of size (sand in Figure 1) are called ‘well’ graded or continuously graded.

Aggregates

Crushed aggregate is produced by crushing quarry rock, boulders, cobbles, or largesize gravel. Recycled concrete is a viable source of aggregate and has been satisfactorily used in granular subbases, soilcement, and in new concrete. After harvesting, aggregate is processed: crushed, screened, and washed to obtain proper cleanliness and gradation.

The Effect of Aggregate Properties on Concrete

The grading or size distribution of aggregate is an important characteristic because it determines the paste requirement for workable concrete. This paste requirement is the factor controlling the cost, since cement is the most expensive component. It is therefore desirable to minimize the amount of paste consistent with the production of ...
