The term fineness modulus FM is a ready index of coarseness or fineness of the agrial It is an empirical factor obtained by adding the cumulative percentages of aggregates retained on each of the standard sieves and dividing this sum arbitrarily by 100 Apparatus Eclectic balance Sieve ASTM Standard Materials Fine aggregate =161410gm...

Jul 23 2020 0183 32 Fineness modulus indicates the relative fineness or coarseness of the aggregate or it is gradation Higher the fineness modulus value for aggregate coarser is the gradation The standard codes of practice suggest doing the following for different aggregat Important factors promoting the alkali-aggregate reaction of aggregates are as...
