A Detailed Guide On Grading Of Aggregates.

Grading of Aggregates. Grading of aggregates is determining the average grain size of the aggregates before they are used in construction. This is applied to both coarse and fine aggregates.The aggregate sample is sieved through a set of sieves and weights retained on each sieve in percentage terms are summed up.

Sieve Analysis Of Aggregates

How To Do Sieve Analysis Of Aggregate

Nov 09, 2014 2. Reduce the sample to “Minimum Mass of Test Portion.” There are minimum masses that you would need to take corresponding to each size of aggregate that you are going to do sieve analysis.This time we’re going to use 20mm aggregate, so we will reduce the sample to 2 kilograms (minimum weight) but you can make it more than 2kgs as long as you will follow the process.

Fine Aggregate Specific Gravity

If the aggregate slumps on the first Cone Test, it is assumed that the aggregate has already dried beyond the SSD condition (Figure 10). The aggregate can be restored by thoroughly mixing in a small amount of water and allowing the aggregate to stand in a covered container for 30 minutes. The drying process can then be resumed (AASHTO, 2000c [1]).

Why Is Materials Testing Important? | Laboratory Testing Inc.

Materials Testing is performed for a variety of reasons and can provide a wealth of information about the tested materials, prototypes or product samples. The data collected during testing and the final test results can be very useful to engineers, designers, production managers and others.
