Sand Equivalent Test Vs Silt Content Test - Concrete ...

Hi, What is the difference between sand equivalent test values and sa simple silt content test? I mean when you finish a SE test, specs say that min 75% SE value is accepatable, which means max 25% of clay/silt content is acceptable limit for sand used in structural concrete!

Sand Equivalents - Quality in California

2021-2-23  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.

Quality Testing of Sand for Concrete Quality Testing

2021-3-1  Quality Testing of Sand at The Construction Site for The Concrete. There are different methods for testing the quality of sand at the construction site for concrete construction. The quality of the sand is as important as other materials for concrete. The most different, which passes through the 4.75 mm IS strainer, is known as the fine aggregate.
