AGGREGATE CRUSHING VALUE 1.Objective The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. With aggregate of aggregate crushing value 30 or higher, the result may be anomalous, and in such cases the ten percent fines value should be determined instead.

A balance should be accurate up to 1 gm 2. IS sieves of size 12.5 mm, 10 mm, and 2.36 mm 3. Mould, measuring cylinder with plunger and base plate 4.
Aggregate Crushing Value (ACV) and Ten Percent Fines Value (TFV) These tests are a measure of the crushing properties of aggregate and use the same basic equipment. The ACV test requires a standard load of 400 kN to be applied over a period of 10 minutes while the TFV test measures the force required to produce a specified depth of plunger
Structural Uses of Aggregate Base. When doing structural foundations or base course under concrete slabs and asphalt pavement roadways, Aggregate Base is in use. It can be placed by attentive spreading then compacting. The sub-base if formed by dust and small chipped aggregate layers, typically Crushed Fines.
Aggregate crushing plant is a combination of feeding device, crusher device, conveying device, screening device and power system.:::A crushing plant has different stations (primary, secondary, tertiary,) where different crushing, selection and transport cycles are done in order to obtain different stone sizes or the required granulometry. With this process, the aggregate used for mortars
From the calculations done we came to know that the sargodha crush is a good aggregate and margala crush and the mixture of margala and Sargodha are also close to the maximum allowable limit for good aggregates Hence they can be acceptable as their Aggregate Impact value is less then 35.
Crushing Equipment Purchase Price Means Less Than You Think. The purchase price of crushing equipment or consumables such as screen media vary at least 50% in terms of purchase price. Scan the market and you will find 300 Horsepower Cone Plants range from $300,000 to $600,000. Screen cloth for a carry deck ranges from $1,000 to $7,000.
Crush and screen reclaimed asphalt pavement (RAP) greater than 2 in [50mm] so all material is prepared for recycling and a uniform mixture is maintained. Handle, screen and crush material so as not to produce unnecessary fractured aggregate or cause undue degradation. Ensure 100% of RAP used passes through a 2 in sieve Section 4

The crushed aggregate sample which is finer than 2.36 mm is separated and expressed as a percentage of the original weight taken in the mould. The percentage of weight passed through the 2.36m IS sieve is known as Aggregate crushing value.. In situations, when the aggregate value 30 or higher the result may be a mistake and in such cases, the “ten percent fines value” should be determined
Aggregate crushing value test on coarse aggregates gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load. Coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions.

Coarse aggregate crushing value is the…
Coarse crushed aggregate is commonly used in landscaping designs. All aggregate is divided into two types: fine and coarse. Fine aggregate is broken up into smaller pieces than coarse aggregate. When put through a separator or aggregate washer, coarse crushed aggregate will pass through a 3-inch (7.62-cm) sieve but will not go through a No. 4
The crushing value of aggregates is measured in the ratio between the crushed aggregates, obtained from the IS sieve 2.36mm and the weight of the dried aggregate sample. At least three samples should be tested from the same batch and average value to get accurate results. The crushing value of aggregate = (W2/W1) x 100. Lab Report

The aggregate crushing value (ACV) of an aggregate is the mass of material, expressed as a percentage of the test sample. which is crushed finer than a 2,36 mm sieve when a sample of aggregate passing the 13,2 mm and retained on the 9,50 mm sieve is subjected to crushing under a gradually applied compressive load of 400 kN. 2 APPARATUS
aggregate impact value is a measure of resistance to sudden impact or shock, which may differ from its resistance to gradually applied compressive load. 3. APPARATUS The apparatus of the aggregate impact value test as per IS: 2386 (Part IV) – 1963 consists of:
Importance of crushing value of aggregate Products. As a leading global manufacturer of crushing, grinding and mining equipments, we offer advanced, reasonable solutions for any size-reduction requirements including, Importance of crushing value of aggregate, quarry, aggregate, and different kinds of minerals.
Aggregate Crushing Value. 1.0 Introduction. The principal mechanical properties required in stones are satisfactory resistance to crushing under the roller during construction and adequate resistance to surface abrasion under traffic. Aggregates used in road construction, should be strong enough to resist crushing under traffic wheel loads.
The aggregate impact value indicates a relative measure of the resistance of aggregate to a sudden shock or an impact, which in some aggregates differs from its resistance to a slow compressive load. The method of test covers the procedure for determining the aggregate impact value of coarse aggregates
2. Spread each aggregate fraction individually on a clean, flat surface in a well-lit area. The surface must be large enough to permit the material to be spread thinly for inspection. 3. Use the knife-edge of a spatula or similar tool to separate uncrushed particles from crushed particles. 4.
