2011-3-1The value of finess modulus of natural sand is 1.95 according to European standard . It indicates that the sand is fine and may improve workability of concrete at the expense of the strength. The finess modulus of recycled sand is 3.12, it is a coarse sand which would help to have good resistance values but probably not a good workable mix.
Read MoreFineness modulus of sand fine aggregate is an index number which represents the mean size of the particles in sand. It is calculated by performing sieve analysis with standard sieves. The cumulative percentage retained on each sieve is added and subtracted by 100 gives the value of fineness.

Thats because the stress was so great between the outer compressive layer and the inner tension layer. JAMIE HYNEMAN That when released, it was a catastrophic result.
Read More2020-7-14The ability of cement to retain its volume after it gets hardened is known as Soundness of Cement. That means the cement should be at minimum volume change after it gets hardened. The test conducted to identify the excess amount of lime in cement is known as soundness test of cement. Significance Why are we calculating this value for cement.
