[email protected]Significance of Aggregate Crushing ValueTest The crushing value test is conducted on aggregates that are used for the construction of roads. Lower crushing value aggregates give much more durability for roads due to its lower crushed fraction under the compression load. The road is subjected to motion pressure continuously.
Chat OnlineSignificanceofaggregate crushing value. The process flow for stationary concrete batch plant will start from feeding of aggregates to the feeder bins. Process of concrete mixing plants end at the output of fresh concrete from the mixer. Modern batch mix plant consists of components like feeder bins, conveyor belts or skip hoist, weigh.
May 08, 2013·Aggregate crushing Value=(W B /W A) × 100 Record. The mean of the two results is reported to the nearest whole number as theaggregate crushing valueof the tested material. Safety & Precautions: Use hand gloves while removing containers from oven after switching off the oven. To wear safety shoes & helmet during the time of test.
Experiment No. 4: Determination of theaggregateimpactvalueof different coarseaggregatesamples. (BS 812) Scope &significance:AggregateImpactValueTheaggregateimpactvaluegives a relative measure of the toughness or the resistance ofaggregatesudden shock or impact is not proportional to the resistance to a slowly applied compressive load.
Calculation ofaggregate crushing value. Theaggregate crushing valueis defined as the ratio of the weight of fines passing through specified IS (here 2.36mm sieve) to the total weight of sample expressed in percentage. W1= Weigh of the total aggregates (Wa-We) W2= Weigh of aggregates passing through 2.36mm IS sieve.
