Aggregates may be broadly classi fied as natural or artificial both with respect to source and to method of preparation natural sands and gravels are the product of weathering and the action of wind or water while manufactured crushed fine aggregate and crushed stone coarse and fine aggregate are produced by crushing natural stone

Effect of aggregate properties on the crushing strength of concrete but owing to the non homogeneity of the aggregates the results will not be comparable with those obtained in the standard test about 5 kg of material consisting of aggregate passing 125 mm and retained on 10 mm sieve is taken

Crushing strength of road stone may be determine either on aggregates or on cylindrical specimen cut out of rocks the two tests are quite different not only in the approach but also in the expression of the results aggregate used in road construction should be strong enough to

Aggregates impact crushed a1 coarse aggregates and vertically shafted a2 coarse aggregates were 09 14 and 14 respectively and weight per unit of volume for fine aggregates impact crushed a1 coarse aggregates and vertically shafted a2 coarse aggregates were 1650 kgm3 1420 kgm and 1375 kgm3 respectively impact crushers break materials according to

Mar 14 2019 this compressive strength test was carried out according to bs en 123904 filling 150 mm cube mould with concrete in three layers of approximately 50 mm with each layer receiving 25 blows for proper compaction the mix ratio was 124 with the coarse aggregate being at 100 gravel and replaced by palm kernel shell at 10 25 50 75 and 100

The aggregate crushing value test indicates the strength of aggregate which is the most essential property of coarse aggregate the aggregate crushing value provides a relative measure of resistance to crushing under a gradually applied compressive load for achieving a high quality of pavement aggregate of higher crushing strength ie low

Aggregate crushing value this test helps to determine the aggregate crushing value of coarse aggregates as per is 2386 part iv 1963 i the aggregates passing through 125mm and retained on 10mm is sieve are ovendried at a temperature of 100 to 110oc for 3 to 4hrs

Larger the size of aggregate will decrease strength of the concrete because surface area of this aggregate is low lesser the size of the aggregate will lead to increase the strength of the concrete
