Low Sand Equivalent Value Concrete

Sand Equivalent - Pavement Interactive

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.

Sand Equivalents - Quality in California

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.

Hydraulic conductivity - Wikipedia

Hydraulic conductivity, symbolically represented as , is a property of vascular plants, soils and rocks, that describes the ease with which a fluid (usually water) can move through pore spaces or fractures.It depends on the intrinsic permeability of the material, the degree of saturation, and on the density and viscosity of the fluid. . Saturated hydraulic conductivity, K sat, describes water ...
