Aggregate Lab Equipment

Product Details:

The aggregate impact value of coarseaggregate provides a relative measure ofthe resistance of an aggregate to sudden

shock or impact. The oven dried andaccurately weighed aggregates are subjectedto a total of 15 blows of specified weight and fall and percentage of fines formed in terms of

the total weight of the sample is expressed as

the aggregate impact value.

Product Details:

The bulk density measurement is used for
determining the weight per cubic meter of
freshly mixed concrete (density of concrete)
from which the yield of concrete per cubic
meter can be calculated

Product Details:

Elongation index of an aggregate is the
percentage by weight of particles whose
greatest dimension (length) is greater than
one and four-fifth times their mean dimension.
It is measured on particles passing through mesh size of 63mm and retained on mesh size of 6.3mm. Determination of
elongation index of coarse aggregate

Product Details:

Consists of both end open cylinder,
base plate, a plunger handle and
tamping rod.7.5 cm diameter for
2 mm to 6 mm aggregate

Product Details:

For determination of flakiness index
of coarse aggregate, where the  size
of the coarse aggregate are larger than
6.3mm .

Product Details:

Aggregate crushing value test on coarse aggregates gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load.
Coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions.

Aggregate crushing value is a numerical index of the strength of the aggregate and it is used in construction of roads and pavements.

Crushing value of aggregates indicates its strength. Lower crushing value is recommended for roads and pavements as it indicates a lower crushed fraction under load and would give a longer service life and a more economical performance.

The aggregates used in roads and pavement construction must be strong enough to withstand crushing under roller and traffic. If the aggregate crushing value is 30 or higher’ the result may be anomalous and in such cases the ten percent fines value should be determined instead.
