Grading of Fine Aggregates - US The fineness modulus must be between 2.30 and 3.10 to meet the requirements of US standard ASTM C33. This effectively sets grading limits for fine aggregates. The grading zone of fine aggregates is limited to those with a finenesss modulus of between 2.30 and 3.10.

Fine aggregates are basically natural sand particles from the land through the mining process, the fine aggregates consist of natural sand or any crushed stone particles that are ¼” or smaller. This product is often referred to as 1/4’” minus as it refers to the size, or grading, of this particular aggregate.

The suitability of the fine sand of zone 4 for use in reinforced concrete should be tested. For sands, the sand content of the mix should be low whose greater part is smaller than 60C micron. In general, finer the grading of the fine aggregate, higher should be the coarse/fine aggregate ratio. Typical values are shown in Table 4.23.
Bavarder sur InternetIn 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. Voids in the coarse aggregate are filled in by sand and voids in the sand are filled in by cement. Mix that occupies the least volume is the densest and will produce the best results.

Grading of aggregate is the particle size distribution, which is determined by sieve analysis. The particle size distribution of a mass should be such that, voids between the coarse aggregate should be filled by fine aggregates. The grading of the aggregate affects the workability of concrete. When grading of aggregate is done by sieve analysis.

This process of separating the sample of aggregate into categories of size is also known as gradation. To do so we use sieves mentioned in IS 383-2016.

FINE GRADING Fine grade is required to be provided for the final trimming and checking of the cross section and grade. Stakes are usually set at 50 ft intervals near each edge of the subgrade with a grade mark established at some known distance above the actual finish subgrade elevation.
