Sand Equivalents Quality in California

Apr 30, 2011· So if your sample has a 90 sand equivalent that means that 90% of the sample was good material and 10% was detrimental. If you have a 40 sand equivalent that means that 40% of the sample was good material and 60% was detrimental. Many materials such as concrete sands will have high SEs, in the 80s or 90s but it is very rare to see a 100 SE.

tivity and amount are reflected in the sand equivalent value hut not in the loss by decantation. Clay contami­ nants in concrete aggregate affect concrete properties primarily through their effect on water demand.

Jul 17, 2017· A great reuse of old concrete is as a construction aggregate. It saves money on both sides of the process, the cost of disposing of concrete at a landfill and the purchase of new aggregate from a quarry. Like decomposed granite, recycled concrete can be crushed to a consistent grade.

Sand Equivalent Value of Soils and Fine Aggregate

sand reading clay reading • If the calculated sand equivalent is not a whole number, report it as the next higher whole number. • Higher sand equivalent values indicate “cleaner” (less fine dust or clay-like materials) aggregate. • Typical sand equivalent values range from less than 30% to more than 90%.

Standard Test Method for Sand Equivalent Value of Soils

5.2 A minimum sand equivalent value may be specified to limit the permissible quantity of claylike or clay size fines in an aggregate. 5.3 This test method provides a rapid field method for determining changes in the quality of aggregates during production or placement.

paste needed to make concrete using the aggregate. For instance, sand with a low fineness modulus has more voids in it and more particle surface, thus, more paste is needed to fill voids and cement the particles together than would be needed for a coarser sand.

Sand Equivalent Value Soil testing engineering Eng-Tips

Jun 30, 2009· 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. Either clay content should be calculated as 100-sand equivalent value to set minimum requirement as above or if we use sand

What is the R-value for earth, dirt, soil, backfill, or

Some sources quote a much higher R-value for sand and gravel aggregate but you need to look at the thickness or amount of sand or gravel when you see such quots. For example some cite sand and gravel aggregate as providing R 1.11 FOR 8 INCHES of thickness. That's equivalent to an R-value of R 0.1388 per inch, but without considering moisture level.
