This document gives the determination of aggregate crushing value (ACV) of aggregates. This gives a relative measure of the resistance of the aggregate crushing under the gradually applied compressive load. The method is applicable to aggregates passing a 14,0 mm test sieve and retained on a .
The usual tests to control the quality of aggregates in California are grading, speci fic gravity, unit weight, absorption, soundness, Los Angeles rattler, Rvalue, clean ness, and sand equivalent. Generally, not all of these tests are applied to any one aggregate product. These tests are used on the premise that they will control the

coarse aggregate contents with aggregate volume factors (ACI ) and Watertocementitious material ratios range from to Compressive strengths range from 25 MPa (3,670 psi) to 97 MPa (13,970 psi). Compression test results show that highstrength concrete containing basalt
apply to the amounts of aggregate (by mass) in percentages that pass through an assortment of sieves (Fig. 55). For highway construction, ASTM D 448 (AASHTO M 43) lists the same 13 size numbers as in ASTM C 33. 81. Chapter 5 Aggregates for Concrete. Table Characteristics and Tests of Aggregate
Aggregate impact value gives a relative measure of the resistance of an aggregate to sudden shock or impact, As an alternative to crushing value, the aggregate impact value should not exceed 45% by weight for aggregates used for concrete other than for wearing surfaces and 30% by weight for concrete for wearing surfaces, such as runways, roads ...

· Aggregate crushing test values indies the strength of aggregate and hence it is very significant. Similarly we can say crushing value is the relative measure of resistance of an aggregate under gradually applied compressive loads. Higher crushing strength means lower crushing value and vice versa. If the aggregate crushing value is less than ...
Test Method: IS: 2386 (P1) 1963. Impact Value: This test helps in determining the value which indies the ability of an aggregate to resist crushing. The lower the figure the stronger the aggregate, the greater its ability to resist crushing. Test Method: IS: 2386 (P .
crushing value test is an important aggregate test. It gives a numerical index of the strength of the aggregate and is used for concrete in the construction of roads and pavements. Aggregates, with a minimal crushing value, are recommended for roads and pavements because they indie a lower crushed fraction under load and would

Definition The 10 per cent Fines Aggregate Crushing Value is the force in kN required to crush a sample of 13,2+9,5mm aggregate so that 10 per cent of the total test sample will pass a 2, 36 mm sieve. 2 APPARATUS As in SABS ...
Aggregates possessing high resistance to crushing or low aggregate crushing value are preferred for use in high quality pavements. The apparatus for the standard test consists of a steel cylinder 152 mm diameter with a base plate and a plunger, compression testing machines, cylindrical measure of diameter 115 mm and height 180 mm, tamping rod and sieves.

· For this purpose, the mineralogical, physical, and mechanical properties of various hard rocks were determined. A new compressive crushing value (CCV) testing methodology was proposed. The results obtained from CCV tests were compared with those from mineralogical inspections, rock strength as well as mechanical aggregate tests.
Aggregate abrasion characteristics are important because the constituent aggregate in HMA must resist crushing, degradation and disintegration in order to produce a high quality HMA. What Is Abrasion Value Test? Abrasion Test is the measure of aggregate toughness and abrasion resistance such as crushing, degradation and disintegration.
