aggregate impact value application

3. Value-added is simply the total time spent minus time spent on appraisal and rework. Improving effectiveness is increasing value-added. Any and all improvement initiatives can set goals and measure improvements in terms of the impact on value added. When measured, which rarely occurs, value-added is commonly about 30 percent of the total effort.

ii) the percentage by weight of the total sample passing through one sieve and retained on the next smaller sieve, to the nearest 0.1 percent. The results of the sieve analysis may be recorded graphically on a semi-log graph with particle size as abscissa (log scale) and the percentage smaller than the specified diameter as ordinate.

Jul 14, 2018· Aggregate Impact Value Test. AIV test is conducted to determine the Aggregate Impact Value of Coarse aggregate. 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 slow compression load.

APPLICATIONS OF AGGREGATE CRUSHING TEST: The aggregate crushing value is an indirect measure of crushing strength of the aggregates. Low aggregate crushing value indicates strong aggregates, as the crushed fraction is low. Thus the test cans be used to assess the suitability of aggregates with reference to the crushing strength for various types of pavement components.

The Aggregate Impact Value Testing Apparatus, meets with BS 812, it is robustly designed to determine the Aggregate Impact Value (AIV) of aggregates which provides a relative measure of the resistance of an aggregate to sudden shock or impact.

Experiment No. 4: Determination of the aggregate impact value of different coarse aggregate samples. (BS 812) Scope & significance: Aggregate Impact Value The aggregate impact value gives a relative measure of the toughness or the resistance of aggregate sudden shock or impact is not proportional to the resistance to a slowly applied compressive load.

Aggregate is a granular material obtained by processing natural materials.BS882 splits aggregate into coarse and fine elements, coarse being described as gravel or crushed rock and fine being described as sand.Aggregate consists of particles of a rock, of a controlled particle size distribution, used in the construction of a building or civil engineering structure.
