DETERMINATION OF AGGREGATE CRUSHING VALUE

The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Crushing value is a measure of the strength of the aggregate. The aggregates should therefore have minimum crushing value. 3.

07/07/2014· Crushed Gravel Sand– it is the fine aggregate produced by crushing natural gravel. According to size the fine aggregate may be described as coarse sand, medium sand and fine sand. IS specifications classify the fine aggregate into four types according to its grading as fine aggregate of grading Zone-1 to grading Zone-4. The four grading zones become …

Aggregate Crushing Value Test -Determine Aggregate ...

Aggregate crushing value is a numerical index of the strength of the aggregate and it is used in construction of roads and pavements. Crushing value of aggregates indicates its strength. Lower crushing value is recommended for roads and pavements as it indicates a lower crushed fraction under load and would give a longer service life and a more economical performance.

Clean v. Minus: Your Questions Answered - Washington …

The pieces are sorted by using screens with different sizes of holes. What is the difference between clean and minus (for example, 1¼” clean versus 1¼” minus)? Clean rock products contain no fines (small particles of ground rock). Minus rock does contain fines. Fines help a product compact. For example, if you’re building a driveway over soft ground, a minus product …

This type of aggregate is described as how it is graded. For example, ¾” nominal size graded aggregate means that most of the aggregate passes a 3/4” sieve. All-in aggregate, similar to that of its name, is aggregate containing a proportion of material of all sizes from a pit, crushing plant or river bed. Also known as Ballast, this type of material is generally used to repair small ...

Crushing for larger top-size aggregate generally produces higher coarse RCA yields because less crushing is necessary. For example, 55 to 60 percent coarse RCA yield is common when crushing to ¾ in. (19 mm) top size, while 80 percent yield is not uncommon when crushing to 1.5 in. (28 mm) top size (NHI 1998).
