For tests on the smaller sizes use instead of 2.1 a crushing cylinder of diameter 77 mm depth 75 mm and a plunger of diameter 75 mm instead of 2.6 a measure with internal diameter 60 mm and depth 90 mm. 5.2 If the test is to be repeated a similar mass of aggregate is used.
aggregate crushing value range activesecurityservices. Aggregate (composite) Wikipedia. Aggregate is the component of a composite material that resists compressive stress and provides bulk to the composite material. For efficient filling aggregate should be much smaller than the finished item but have a wide variety of sizes.

The aggregate crushing value that is toughness measure for the sample of rock due to failure by impact for coarse aggregate samples are as shown in Table 2 and they varied with an average of 26.14% and standard deviation of 4.74%. The standard BS812 Part 112:BS882 1992 prescribes that the maximum crushing values should be 25% for aggregates to be used in heavy duty floor 30% for aggregates to
aggregate crushing value ranges p42nl. Aggregate Crushing Value Civil Engineering according to IS 2386 (Part iv)1963 aggregate crushing value is designed for only for IS Sieves of sizes 125mm 10mm and 236mm for 20mm and 10mm coarse aggregate we need to take different ranges of sieves then cylinders size will also changes
aggregates with typical range values are shown in Table 2. Coarse and fine aggregates are generally sieved separately. That portion of an aggregate passing the 4.75 mm (No. 4) sieve and predominantly retained on the 75 181m (No. 200) sieve is called fine aggregate or sand and larger aggregate is called coarse aggregate.

Aggregate Gradation The distribution of aggregate particles among various sizes usually expressed in terms of cumulative percentages larger or smaller than each of a series of sizes (sieve openings) or the percentages between certain ranges of sizes (sieve openings). Aggregate Impact Value (AIV) As for ACV but subjected to 15 blows impact
