2020-4-11 Source: ASTM Standard C33/C33M The second column in the table shows the aggregate size range that is always decided prior to use. For example, if we are to prepare a concrete mix using an aggregate sample that contains a maximum particle size of 63mm and a minimum particle size of 37.5mm, we’ll look through the second row and the values present in the columns will brief the

The grading of aggregate is plotted in a semi-logarithmic graph to get the particle size distribution curve which is in form of ‘S’. Sieve analysis or sedimentation analysis is performed to find out the grading of the aggregates. Sieve analysis is a procedure in which aggregates are allowed to pass through a set of sieves arranged in ...

2021-11-24 Fineness Modulus of grading of aggregate. Fineness modulus is an empirical factor computed from the sieve analysis. It is defined as the sum of the cumulative percentages retained on the sieves of the standard series ranging from 80mm to 150microns and dividing the sum by 100. When all particles in a sample are coarser then say 600µm, the ...

Quarry Process. Dense graded quarry process is an aggregate material that has been crushed and sized. Quarry process is known by a few different names, including QP, Dense Graded Aggregates (DGA), shoulder stone, item #4, crusher run and DGABC. Quarry process is composed mostly of 1” minus crushed stone and stone dust.

Grading of Aggregates. Grading of Aggregates is one which is made up of stones of different sizes, ranging from large to small (inclusive of sand) so as to have minimum of air voids (and that will have maximum density) when mixed together.In grading of aggregates, the voids in the mixed aggregate would be minimum when the sand is just sufficient to fill the voids in the coarse aggregate.
