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.

INFLUENCE OF THE GRADING OF AGGREGATES ON CONCRETE

INFLUENCE OF THE GRADING OF AGGREGATES ON CONCRETE MIX PROPORTIONS. It is well known that aggregate grading directly influences concrete mix proportions and that satisfactory concrete can be produced with aggregates whose gradings do not fall entirely within normal specifications or conform with typical grading curves.

Effect of aggregate grading on pervious concrete

Effect of aggregate grading on pervious concrete properties 2.2. Aggregate The ground limestone used in the analysis was produced at the Garica Quarry on the Island of Krk. Its proportions and properties are shown in Tables 2 and 3. Depending on mix design the following aggregate fractions were used in the mixes 0-4 4-8 8-16 11-16 and 16-22.

Practical Grading of Aggregates Concrete Technology

Curve No. 1 represents the coarsest grading in each set of curves. These gradings are compara tively workable and can be used for mixes with low watercement ratio or for rich mixes. However it should be ensured that no segregation takes place. At the other extreme curve No. 4 represents a fine grading. It will be cohesive but not very workable.
