Fundamentals of Concrete

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 Below is an example of the mechanical sieve analysis results of a fine and coarse...

Sand Equivalents

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 On ....
