The Contractor may increase the usage of calcareous sand to 70% of the absolute volume of the fine aggregate provided that the fine aggregate meets a minimum insoluble residue of 30% and the processing or manufacturing of calcareous sand removes deleterious coatings and unsound materials.

(ASTM 2009). Briefly, fine aggregate is shaken in a clear graduated cylinder containing a solution of flocculant and preservative. After shaking, the particles are allowed to settle for twenty minutes. The SE value is taken as the ratio of the height of the sand column to the height of the sand and flocculated clay multiplied by one hundred.

The sand equivalency (SE) test (ASTM D2419Standard Test Method for Sand Equivalent Value of Soils and Fine Aggregate) is commonly used in the concrete industry to estimate cleanliness and clay contents of fine aggregates. The SE test measures the ratio of clay .

Aggregates can be classified in many ways. Classification of aggregates based on shape and size such as coarse and fine aggregates are discussed here, Aggregates are the important constituents of the concrete which give body to the concrete and also reduce shrinkage. Aggregates occupy 70 to 80 % of ...

Jun 30, 2009· In our Specification there is a requirement which says, 'the aggregate shall meet the sand equivalent (clay content)requirements... minimum sand equivalent percent 40 ...'. If we see the sand equivalent formula, which is 100*sand reading/ clay reading, the higher the sand reading during testing means it gives higher sand equivalent value, and that means there are less clayey materials.

Average sand: percent: Pebbles and crushed limestone: percent: Trap rock and granite: percent: Porous sandstone: percent: Very light and porous aggregates may absorb as much as: 25 percent by weight

Overview. The fine aggregate specific gravity test (Figure 1) is used to calculate the specific gravity of a fine aggregate sample by determining the ratio of the weight of a given volume of aggregate to the weight of an equal volume of water. It is similar in nature to the coarse aggregate specific gravity test.. Figure 1: Fine aggregate specific gravity sample and pycnometer.

minerals in the aggregate fines were used to make Portland cement concrete to see how they performed as the coarse aggregate fraction of the mixes. Through extensive methylene blue and concrete performance testing, the aim was to establish a threshold methylene blue value (MBV) that corresponds with the maximum permissible clay

task force report on astm d 2419: sand equivalent value of soils and fine aggregate, prepared for astm subcommittee d An interlaboratory study is reported which compared ASTM D 2419 test results using 3 diifferent sample preparation techniques.

Sand equivalent (SE) is done by shaking fine aggregate in a clear graduated cylinder containing a flocculant and preservative solution. After shaking, the particles are allowed to settle for 20 minutes and the SE is taken as the ratio of the height of the sand column to the height of the sand and flocculated clay multiplied by 100.

the sand equivalent value changes from 80 to 100. The value of 100 denotes a completely clean fine aggregate. The sand equivalent test does not tell everything that is needed to know the relative concrete making properties of dif­ ferent fine aggregates. Other factors such as degradation, elas­

proportions of claylike or plastic fines and dusts in granular material and fine aggregates that pass the mm sieve. A minimum sand equivalent value may be specified to limit the permissible quantity of claylike fines in an aggregate. The test may also be used for detemining changes in the quality of aggregates during production or placement.

Standard Method of Test for Plastic Fines in Graded Aggregates and Soils by Use of the Sand Equivalent Test This test is intended to serve as a rapid field test to show the relative proportions of fine dust or claylike material in soils or graded aggregates.

Grading of Aggregates. The proportion of voids to volume of well graded sand is 30 to 35 per cent and that of coarse aggregate between 30 and 45 per cent. This should represent the amount of cement required to fill the interstices in the sand and the amount of sand required to fill the interstices in the coarse aggregate.
