Effect of WFS on concrete mixes M-0 (0% WFS), M-1 (10% WFS), M-2 (20% WFS), M-3 (30% WFS) is shown in Table 6. Compressive strength of control concrete mix M-0, without waste foundry sand, was 28.41 MPa at the age of 28 days. It was observed that concrete mixes made with WFS exhibited higher compressive strength than control concrete. Compressive

What is the FM of concrete sand? Fineness modulus is typically used for sand or cement mixes, which will typically fall within an FM of 2 - 4, with most coming in between 2.2 - 2.8. As a general rule, the lower the fineness modulus, the finer the particles will be, and the higher the fineness modulus, the coarser they will be.

A fineness modulus of the sand is important because of its effect on the water demand of the mix. The finer the sand, the lower the F.M., the more water required for a given slump. The fineness modulus of sand is obtained by adding the cumulative percentages retained on the following standard sieves: 4, 8, 16, 30, 50 is then divided by 100.
