In other words Abrasion and Impact test ( Abrasion test) to determine aggregate quality. The Sodium data from both tests to make a definitive conclusion on aggregate quality. Get Price
Figure Outline form of cylinder and plunger apparatus for the aggregate crushing value and ten percent fines test e) A ventilated oven, thermostatically controlled at a temperature of 1050C plus or minus 50C. f) A rubber mallet, a metal tray of known mass and large enough to contain 3 kg of aggregate and a brush with stiff bristles.
Sep 12, 2015· Then crushed aggregates are then sieved through mm sieve and weight of passing material (W2) is expressed as percentage of the weight of the total sample (W1) which is the aggregate crushing value. Aggregate crushing value = (W1/W2)*100. A value less than 10 signifies an exceptionally strong aggregate while above 35 would normally be regarded as weak aggregates. Also Read: .
Sep 05, 2018· The aggregate crushing value for cement concrete pavement shall not exceed 30%. The aggregate crushing value for wearing surfaces shall not exceed 45%. PURPOSE OF TEST: The strength of coarse aggregate is assessed by aggregate crushing test, the aggregate value provide the relative measure of resistance to crushing under gradually applied compressive load.
To Determine Aggregate Impact Value Theory: ... The crushing aggregate is removed from the cup and sieved is through mm sieve. ... Each layer should be tamped 2 to 3 time with the help of tamping rod. 3. The cylinder of test aggregate with aggregate is carefully leveled and the plunger inserted horizontally on the surface.

Impact and Crushing Value Aggregate Crushing Value (ACV) Sets. UTA0630 Aggregate Crushing Value (ACV) Set Ø 150 mm BS. UTA0640 Aggregate Crushing Value (ACV) Set Ø 75 mm BS. The Aggregate Crushing Value (ACV) Test Set measures how resistant an aggregate is, when being crushed under a gradually applied compressive load.
Crushing value is a measure of the strength of the aggregate The aggregates should therefore have minimum crushing value 3 APPARATUS The apparatus of the aggregate crushing value test as per IS: 2386 (Part IV) ? 1963 consists of:,.
The aggregate crushing value provides a relative measure of resistance to crushing under a gradually applied compressive load. To achieve a high quality of pavement aggregate possessing low aggregate crushing value should be preferred. >> Ver Precio; conclusion of aggregate crushing value. aggregate crushing value experiment crusherasia.
Once the test is complete, the calculated mass of aggregate that has broken apart to smaller sizes is expressed as a percentage of the total mass of aggregate. Therefore, lower abrasion loss values indicate aggregate that is tougher and more resistant to abrasion. Figure 7: .
