The crushed aggregate is allowed to pass through 2.36 mm IS sieve. And the impact value is measured as percentage of aggregates passing sieve (W2) to the total weight of the sample (W1). Aggregate impact value = (W1/W2)*100 Aggregates to be used for wearing course, the impact value shouldn't exceed 30 percent. For bituminous macadam the ...

Aggregate serves as a reinforcement to add strength to composite materials such as concrete. Aggregates can be categorized into three groups: fine aggregate, coarse aggregate, or all-in aggregate. Fine aggregate, such as concrete or masonry sand is defined as material that mostly passes through a 4.75 mm IS sieve.
20–40 mm Aggregate. 20–70 mm, 40 -70 mm : When builders work with a large quantity of concrete, this large fraction of aggregates can be used. They are preferred in the construction of ...
Fine Aggregates are usually sand or crushed stone that are less than 9.55mm in diameter. When the aggregate is sieved through 4.75mm sieve, the aggregate passed through it. Natural sand is generally used as fine aggregate, silt, stone dust and clay also come under this category. The purpose of the fine aggregate is to fill the voids in the ...
Construction aggregate, or simply aggregate, is a broad category of coarse- to medium-grained particulate material used in construction, including sand, gravel, crushed stone, slag, recycled concrete and geosynthetic aggregates.Aggregates are the most mined materials in the world. Aggregates are a component of composite materials such as concrete and asphalt; the aggregate serves as ...
Types of aggregate based on size. There are two types of aggregate used in construction. A) fine aggregate B) coarse aggregate. A) fine aggregate:– the aggregate which are usually passes or sieve through sieve of 4.75 mm size. That is known as fine aggregate and it is normally is sand or crushed stone having size less than 9.5 mm in diameter.
Crushed Sand (Fine Aggregate) 0 – 5 mm (9% to 11% filler) Classified Crushed Sand (Fine Aggregate) 0 – 5 mm (less than 3% filler) Crushed Aggregate (Coarse Aggregate) 5 – 10 mm
Crushed coarse aggregate shall not have more than 50 percent wear at 500 revolutions as determined by ASTM C 131. When the fraction of the aggregates retained on the No. 4 mesh (4.75 mm) sieve is subjected to five cycles of the sodium sulfate soundness test (ASTM C 88), the
Stone and gravel are perfect for laying down as a bed for drainage pipes and concrete slabs. If you are seeking a filler, then you will not do any better than our crushed stone.

Crushed stone is produced by crushing quarry rock, boul-ders, cobbles, or large-size gravel. Crushed air-cooled blast-furnace slag is also used as fine or coarse aggregate. The aggregates are usually washed and graded at the pit or plant. Some variation in the type, quality, cleanli-ness, grading, moisture content, and other properties is expected.
The crushed aggregate shall be composed of sound, hard and durable particles of sand, gravel and rock, and shall be free from elongated particles, injurious quantities of flaky particles, soft shales, organic matter, clay lumps and other foreign matter. All material up to and including 300 mm diameter in Designated Sources and Department Sources
Type 1 Crushed Concrete - 50mm down to dust. Best used as a sub-base for roads, underneath blocks, as well as layering in between concrete or tarmac and as a hard core for projects such as car parks. 6F2. Type 3 Crushed Concrete - 0-63mm reduced fines.
Crushed aggregate is produced by crushing quarry rock, boulders, cobbles, or large-size gravel. Recycled concrete is a viable source of aggregate and has been satisfactorily used in granular subbases, soil-cement, and in new concrete. After harvesting, aggregate is processed: crushed, screened, and washed to obtain proper cleanliness and gradation.
4.1 Some contract documents specify certain aggregate sizes for specific uses or may suggest one or more of these sizes as appropriate for the preparation of various end-product mixtures. In some cases, closer limits on variability of the aggregate grading are required. 5. Manufacture 5.1 The standard sizes of aggregate described in this clas-

Then crushed aggregates are then sieved through 2.36 mm sieve and weight of passing material is expressed as percentage of the weight of the total sample which is the aggregate crushing value. A value less than 10 signifies an exceptionally strong aggregate while above 35 would normally be regarded as weak aggregates.
