Aggregate Dry And Wet Impact Value

The aggregate impact value is a measure of resistance to sudden impact or shock, which may differ from its resistance to gradually applied compressive load. Procedure o f Aggregate Impact Test The test sample consists of aggregates sized 10.0 mm 12.5 mm. Aggregates may be dried by heating at 100-110° C for a period of 4 hours and cooled.

Aggregate crushing value = (W2 x 100) / (W1-W) W2 =Weight of fraction passing through the appropriate sieve W1-W =Weight of surface dry sample. The mean of two result to nearest whole number is the aggregate crushing value. Result The aggregate crushing value of the given sample= Aggregate Crushing Values for Roads and Pavement Construction

The percentage of the material passing through the sieve of 2.36mm to the total weight of the sample in the cup gives the aggregate impact value. Limiting impact value 30% for wearing surface and 45% for other surfaces. 3) Hardness. The hardness of the aggregate signifies the resistance of the aggregate to wear, abrasion, and attrition.

Aggregate can be found in four different moisture states that include oven-dry (OD), air-dry (AD), saturated-surface dry (SSD) and wet. Of these four states, only OD and SSD correspond to a specific moisture state and can be used as reference states for calculating moisture content.

Impact test The aggregate impact test is carried out to evaluate the resistance to impact of aggregates. Aggregates passing 12.5 mm sieve and retained on 10 mm sieve is filled in a cylindrical steel cup of internal dia 10.2 mm and depth 5 cm which is attached to a metal base of impact testing machine.

Dec 01, 2014· Aggregate is classified into two general sizes: coarse grained and fine grained. Coarse aggregate is rock retained on a 3/8-inch (#4 U.S. sieve). Fine aggregates pass the 3/8-inch sieve and are retained on a #200 U.S. sieve. 6. Fine Aggregate. Fine aggregate consists of natural sand, manufactured sand, or a combination.

Water content or moisture content is the quantity of water contained in a material, such as soil (called soil moisture), rock, ceramics, crops, or wood.Water content is used in a wide range of scientific and technical areas, and is expressed as a ratio, which can range from 0 (completely dry) to the value of the materials' porosity at saturation. It can be given on a volumetric or

ratio (w/c) of 0.63. This is different from the 0.4 value actually used by Kistner, because they use wet aggregate in their manufacturing facilities. 2. The equivalent flow table test result for the same mix, but without the coarse aggregate, was 166 mm. This value will thus serve as the reference for subsequent flow table test results. It
