  • Laboratory Testing For Rocks

    Laboratory Testing For Rocks

    Crushed aggregate is produced by crushing quarry rock, boulders, cobbles, or large size gravel. Recycled concrete is a viable source of aggregate and has been satisfactorily used in granular subbases, soil cement, and in new concrete. After harvesting, aggregate is processed crushed, screened, and washed to obtain proper cleanliness and gradation.Aggregate suitable for use as pipe bedding would display a low compaction fraction, indicating it reaches a state of near full compaction under loose placement. Test Method Crushing Value The Aggregate Crushing Value offers a related measure of the resistance of an average to crushing under a compressive load that is gradually applied.

    If the aggregate crushing value is less than 10, it signifies an exceptionally strong aggregate. Whereas, if the crushing value is 35 or above, it would normally be considered as weak aggregate. After performing the test, the crushed material is separated and calculated in terms of percentage of the original weight taken in the mould.Laboratory Jaw Crushers We offer two labratory pilot scale jaw crushers that are ideally suited for reducing rock or similiar materials from 5 down to 1 8 with a minimum of fines creation. Built to withstand the rigors of daily operation, these rugged crushers will produce a uniform finished product, or can be used as a pre breaker for.
