Fineness Modulus is defined as the sum of the cumulative percentages retained on the sieves of the standard series, divided by 100. The standard series consists of sieves, each twice the size of the preceding one (ASTM No. 100, 50, 30, 16, 8, 4) and up to the largest sieve size present. Typical values of fineness modulus range from to ...

For instance, a fineness modulus of can be interpreted to mean the the fourth sieve, No. 16 in the US series, is the average size. It is important to note that the fineness modulus is just one number which only characterizes the average size of the aggregate, and different gradings may have the same fineness modulus.

The percentage passing 150 microns of manufactured sand is relaxed to 20% (while that of natural sand is limited to 10%). As per design and economics, crushed sand can be used to partially or fully replace river sand from a concrete mix. The Availability of crushed sand is not a concern as it can be manufactured from rocks in any season ...

The modulus of elasticity varies in the same way as the compressive strength and a reduction of 30%, 40% and 50% was observed for coarse, fine and both coarse and fine crushed bricks concrete, respectively. • Generally, the process of water absorption of a recycled concrete is similar to that of natural concrete and obeys to the same laws.

Fineness Modulus is an indication grading of particle size. More the value of FM more coarser the aggregate is. Now because density vary with particle size, and also the void spaces inside the concrete is a function of aggregate size, it is very i...

was washed natural quartz sand with a fineness modulus of, matching the lower usable zone ( to ), according to the Brazilian NBR 7211 standard [7]. This size was chosen because it provides smaller segregation of the expanded clay in LWAC. This can be explained by the higher surface area of finer sands, which

The alternatives for river sand are granite powder, iron powder, copper slag, wood waste, fly ash, waste foundry sand, waste, quarry waste, crushed concrete waste etc. The idea of the investigation is to use the excavated soil available at a construction site and unused soil as a fine aggregate in concrete because this will conserve the natural resources and protect the ecological imbalance on environment.
