Fineness Modulus is an indi ion 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...
A trent line of the relationship of concrete compressive strength and fineness modulus of the mix of Sylhet sand and local sand shown with green breaking line is derived using a third order ...
the specific gravity is 2.65. The Fineness modulus of river sand is 5.24. Manufactured Sand: M-Sand was used as partial replacement of fine aggregate. The bulk density of Manufactured sand was 1.75 kg/m3 specific gravity and fineness modulus was found to be 2.73 and 4.66 respectively. The percentage of particles passing
As seen previously stated decreased fineness modulus is preferred from Fig. 9 it can be noted that higher compressive strength was achieved when sand with less fineness modulus was used. The cube with less water absorption has better strength as seen from Fig. 10 .
The premise: "aggregate of the same fineness modulus will require the same quantity of water to produce a mix of the same consistnecy and give a concrete of the same strength." Before calculating FM lab technicians perform a sieve analysis to determine the particle size distribution or grading of the aggregate sample.
As fineness modulus of sand changes from 2.0 to 2.5 there is an increase in compressive strength from 43.07 to 49.00 MPa. i.e. strength increases by 14%. On the other hand by increasing Fineness Modulus from 2.5 to 3 Compressive strength increases from 49.00 to 56.83 MPa resulting in 16% increase in strength.
content also has adverse effect of the strength of concrete due to poor adhesion. Researchers have therefore develop various models for predicting the effect of sand fines and W/C on the strength of concrete. However there is a gap in literature for the combined effect of sand fines and water/cement ratio’s effect on the properties of concrete.
Effect of Fineness of Sand on the Cost and Properties of .
