Sand Equivalent – Pavement Interactive

Sand Equivalent (Figure 1) The sand equivalent test, described in the Test Description section, separates out a fine aggregate sample’s sand and plastic fines and dust portion to determine the content of the latter. lower sand equivalent values indicate higher pastic fines and dust content.

Sand Equivalent Value of Soils and Fine Aggregate

• 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%. • If agg. #1 has SE = 70% and agg. #2 has SE = 40 % that means agg. #1 has more sand and less clay like material than agg. #2.

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.

Sand equivalent test - Wikipedia

The sand equivalent test quantifies the relative abundance of sand versus clay in soil. It is measured by standardized test methods such as ASTM D2419, AASHTO T176, and EN 933-8. The test is used to qualify aggregates for applications where sand is desirable but fines and dust are not. A higher sand equivalent value indicates that there is less ...

How to Calculate Quantities of Cement, Sand and Aggregate ...

So, Sand required = 0.072*1600 = 115 kgs. and Aggregate required = 0.144*1450 = 209 kgs. Considering water/cement (W/C) ratio of 0.55. We can also arrive at the Water required = 50*0.55 = 27.5 kg. So, One bag of cement (50 Kgs) has to be mixed with 115 kgs of Sand, 209 Kgs of aggregate and 27.5 kgs of water to produce M20 grade concrete.

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.
