A test is standardized by IS2386 partIV and used to determine the crushing strength of aggregates The aggregate crushing value provides a relative measure of resistance to crushing under gradually applied crushing load The test consists of subjecting the specimen of aggregate in standard mould to a compression test under standard load conditions Figure 1 Dry aggregates passing through 125

River Gravel Mobile Crushing production line in Kenya is composed of FTM938E69 mobile coarse crushing station, FTM935F1214L（4YK1860） medium and fine mobile crushing and screening station.
Hematite ore is an important mineral resource. With 70% iron content and the large iron output capacity, hematite is the most important iron ore. To improve the comprehensive usage efficiency of hematite, hematite beneficiation process is necessary. We ne
Application:Mining, metallurgy, building materials, highway, railway, water conservancy and chemical engineering.
As a pure natural stone with high usage value, river gravel is formed in the long-term impact, squeeze and friction function. River gravel generally shows the color of black, white, yellow, red, green gray, etc.
Aggregate Crushing Value ACV is an index of loss of coarse aggregate CA under sustained loading However ACV is not considered in concrete mix design according to ACI 2111ACI 2111 2009 In this paper effect of ACV of CA on compressive strength of concrete has been explored Coarse
Crushing test One of the model in which pavement material can fail is by crushing under compressive stress A test is standardized by IS2386 partIV and used to determine the crushing strength of aggregates The aggregate crushing value provides a relative measure of resistance to crushing under gradually applied crushing load
The aggregate crushing value test gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load Aggregate crushing value is defined as the percentage by weight of the crushed or finer material obtained when the test aggregates are subjected to a specified load under

With aggre gate 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 NOTE 2 The standard aggregate crushing test shall be made on aggre a 125mm IS Sieve and retained on a IOmm IS Sieve
An aggregate specimen is compacted into a steel cylinder fitted with a nofriction plunger The specimen is then loaded via the plunger The load crushes the aggregate to an extent depending on the crushing resistance of the material It is measured by a sieving test on the crushed specimen and it is a measure of the aggregate crushing value ACV
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 APPARATUS The apparatus of the aggregate crushing value test
The aggregate crushing value ACV provides relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load Two versions available 150 standard and 75 mm dia The apparatus comprehend cylinder plunger base plate tamping rod and measure
