الحصول على السعرMar 15, 2017 · Based on the findings of this summary, the following items may be drawn as following. (1) The value of compressive strength, flexural strength and static modulus of elasticity reduce significantly with increased crushing index of recycled aggregates. The most reduction of strength occurs when crushing index is more than 24%. (2)

الحصول على السعرSummary. Individual aggregate particles of specific sieve sizes are tested for ratios of width to thickness, length to width, or length to thickness. The test is performed on a sample of coarse aggregate reduced from a representative field sample. The sample is sieved to separate each size larger than the inch ( mm) sieve.

الحصول على السعرAug 27, 2019 · The aggregate crushing value is a numerical index of the resistance of an aggregate to crushing under a gradually applied compressive load. It is expressed as the percentage by mass of the crushed (or finer) material obtained when the test sample is subjected to a specified load under standard conditions. Aggregates with lower crushing value ...
الحصول على السعرJul 18, 2021 · Aggregate crushing value = = (Weight of fraction passing through the mm sieve) / (Weight of surface dry sample) = (W 2 x 100) / (W 1W) Where W is the weight of empty cylinder. Result. The mean of the two results shall be reported to the nearest whole number as the "aggregate crushing value" of the size of the material tested.

الحصول على السعرAggregate crushing value test apparatus is used for measuring resistance of an aggregate to crushing. Made of Mild Steel comprising of: Cylindrical Cell, 150mm internal dia x 130 to 140mm height, Plunger, 148mm dia x 100 to 115mm height, Base Plate, 200 to 230mm square x 6mm thickness, Tamping Rod, 16mm dia x 450 to 600mm length.
الحصول على السعرApr 26, 2018 · Calculation of aggregate crushing value. The aggregate crushing value is defined as the ratio of the weight of fines passing through specified IS (here sieve) to the total weight of sample expressed in percentage. W1= Weigh of the total aggregates (WaWe) W2= Weigh of aggregates passing through IS sieve.
الحصول على السعرAggregate Crushing Value (ACV) The aggregate Impact value gives a relative measure of the resistance of an aggregate to sudden shock or impact, which in some aggregates differs from its resistance to a slowly applied compressive load. With aggregate of aggregate impact value higher than 30 the result may be anomalous. Also, aggregate sizes ...

الحصول على السعرIncreased particle index value or uncompacted voids in coarse aggregate also provide increased rutting resistance. The latter combine the effect of shape, angularity, and texture. â ¢ The current Superpave specifiion levels for coarse aggregate angularity have been adopted by 39% of the agencies that specify ASTM D5821 or an equivalent.
