Sand Equivalent Test Set with Case
The sand equivalent is the ratio of the height of sand to the height of clay times 100.

It has been found that the activity as well as the amount of the minus no. 200 mesh fraction of concrete aggregates affects the properties of concrete. Both activity and amount are re flected in the sand equivalent value but not in the loss by decan tation. Clay contaminants in concrete aggregate affect concrete properties primarily through ...

Investigation into the Effect of Replacing Natural Sand by
When the normalized values are lower than 1, the reference concrete exhibits higher compressive strength values, thus better concrete performance than the crushed sand concretes. The representation of Fig. 5 confirms that, for Mix 30 and Mix 40, the crushed sand concretes had equivalent or slightly lower compressive strengths …

Fines characterization through the methylene blue and sand equivalent
In France, the SE value is measured on grain sizes 0/2 mm with a maximum percentage of 10% fines. If the material contains more than 10% fines in these grain sizes, sand has to be added to lower the value. Product Standard SIST EN 13242 defines the procedure in SIST EN 933-8:2000: assessment of fines—sand equivalent test, to be …
Roughness Coefficient
Equivalent Sand Roughness Coefficient (ks) (m) The Roughness Coefficient is a measurement of the average roughness of the wetted perimeter of a pipe or conveyance. This allows the Colebrook-White formula to correct for the effect of this roughness slowing down the water as it moves through the pipe or conveyance. Typical values are given …

The effect of natural sand composition on concrete strength
There is no absolute value given in published standards that limits these values. However, results based on past research indicate that if the methylene blue value is below 1 g/kg, there is no negative effect on concrete strength; a high sand equivalent value for fine aggregate indicates a positive effect on concrete properties [27], [28].
