    AGGREGATE CRUSHING VALUE 1.Objective The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. With aggregate 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.Crushed aggregate requires slightly higher values. Fine aggregate content is usually 35 to 45 by mass or volume of the total aggregate content. CHARACTERISTICS OF AGGREGATES. The important characteristics of aggregates for concrete are listed in Table 5-2 and most are discussed in the following section Grading. Grading is the particle-size.

    Crushing Machine, Tamping Rod, Trowel, Weighing Balance, Cylindrical Mould, Plunger etc. Description Aggregates crushing value The aggregates crushing value is the ability of an aggregate to resist crushing under a gradually applied compressive load. Impact value is the resistance of an aggregate to sudden or impact load.Conclusion From the experiment, we get 6.02 where it still not exceeding JKR’s standard, 30 . So we can conclude that the aggregate crushing value provides a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. The aggregate are mild tough to have the resistance pressure under traffic wheel loads such as car, lorry, motorcycle and etc.

  • Determination Of The Aggregate Crushing Value (acv)

    Determination Of The Aggregate Crushing Value (acv)

    Calculation of Aggregate Crushing Value. The crushing value of aggregates is measured in the ratio between the crushed aggregates, obtained from the IS sieve 2.36mm and the weight of the dried aggregate sample. At least three samples should be tested from the same batch and average value to get accurate results.The Aggregate Crushing Value (ACV) Test Set provides a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Each set consists of steel cylinder, plunger, base plate, cylindrical measure and tamping rod. All parts of the apparatus are powder coated or galvanized steel, heat treated and ground.
