After,Effect of Fineness of Sand on the Cost and,Fineness Modulus of Sand affects Compressive and flexural strength of Concrete. Sand, with higher FM, results in higher strength of concrete. It is evident by cost benefit ratio that overall concrete mix is becoming economical if we use sand with higher FM. The results indicate that with the increase in FM, workability gets affected considerably. The cement demand also gets modified. Some of,Cement Fineness Concrete Construction Magazine,In airentrained concrete the effect of fineness of cement on workability is very much less pronounced. 4.

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 modulus.Can Changes in Fine Aggregate Affect Concrete,,The fineness modulus of the fine aggregate is required for mix proportioning, since sand gradation has the largest effect on concrete workability. Concrete made with a fine sand (low fineness modulus) has much higher paste requirements for good workability. ASTM C 33, "Standard Specification for Concrete Aggregates," requires that the fineness modulus not vary by more than 0.2 from the value,HOW FINE AGGREGATES AFEECTS CONCRETE MIX,1. Fineness Modulus.

Read MoreWhat is Fineness Modulus of Aggregate? Fineness modulus is an empirical factor obtained by adding the cumulative percentages of aggregate retained on each of the standard sieves ranging from 80 mm to 150 micron and dividing this sum by 100. Why to Determine Fineness Modulus? Fineness modulus is generally used to get an idea of […]Fineness Modulus  an overview  ScienceDirect,It should be reminded that the fineness modulus can not reflect the quality of their grading regions. The sand with the same fineness modulus can have very different grading regions. Therefore, the particle gradation and the fineness modulus should be considered in the preparation of concrete.How does the fineness modulus of aggregate,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...
