MATERIAL SPECIFICATION FOR AGGREGATES

Coarse aggregate composed of 80% siliceous aggregates as determined by at least -609 shall be LS tested in a salt scaling test according to LS-412 together with either the fine aggregate that the coarse aggregate is intended to be used with or a fine aggregate from the same geographic area as the coarse aggregate Get price

Shape Size

Coarse aggregates are classified into two main groups (i) single-size aggregate and (ii) graded aggregate Single-size aggregate is based on a nominal size specification It contains about 85 to 100 percent of the material which passes through that specified size of the sieve and zero to 25% of which is retained in the next lower sieve A Get price

The Effect of Aggregate Properties on Concrete

Aggregate is classified as two different types coarse and fine Coarse aggregate is usually greater than 4 75 mm (retained on a No 4 sieve) while fine aggregate is less than 4 75 mm (passing the No 4 sieve) The compressive aggregate strength is an important factor in the selection of aggregate Get price

What is the difference between fine aggregate and coarse

Strength

To obtain high strength concrete coarse aggregate size is usually held to a maximum size of 19 mm but additional cement is required for the additional surface area The fine aggregate can generally contain less material passing 300 um and 150 um sieve because of the higher cement content Get price

Critical Grain Size of Fine Aggregates in the View of the

The absorption ratio of each fine aggregate sample was evaluated based on ASTM C128 (ASTM International 2015) Table 2 lists the fine aggregate samples' absorption rates The absorption ratio increased as the mean size of the fine aggregate sample decreased as expected Notably for G 0 34 about 7 26% of the highest absorption was observed Get price

HOW TO CLASSIFY AGGREGATES ACCORDING TO SIZE

According to size the aggregates are classified as Fine Aggregate Coarse Aggregate All in Aggregate Fine Aggregate It is the aggregate most of which passes 4 75 mm IS sieve and contains only so much coarser as is permitted by specification According to source fine aggregate may be described as Natural Sand– it is the aggregate []Get price

Uses of Aggregates in Construction Roads Railway and

The smaller the aggregate size the greater its surface area and the more binding material (cement) will be required resulting in a higher cost The greater the aggregate size the larger will be the voids resulting in wastage of binding material (cement) Hence a mixture of coarse and fine aggregate is used in concrete to avoid both these Get price

TYPES OF AGGREGATE

TYPES OF AGGREGATE — As with fine aggregate for increased workability and economy as reflected by the use of less cement the coarse aggregate should have a rounded shape Even though the definition seems to limit the size of coarse aggregate other considerations must be accounted for Get price

Grading of Aggregates

The volume of the coarse aggregate is generally taken as twice that of the fine aggregate but variations of its proportions may be made within the limits of 1 5 to 3 times the volume of the fine aggregate to Suit the size and grading to secure dense and workable concrete Get price

DETERMINATION OF FINENESS MODULUS OF COARSE

The cumulative percentage retained on each sieve is added and subtracted by 100 gives the value of fine aggregate Higher the aggregate size higher the Fineness modulus hence fineness modulus of coarse aggregate is higher than fine aggregate Coarse aggregate means the aggregate which is retained on 4 75mm sieve when it is sieved through 4 75mm Get price
