    Oct 25, 2009· The fineness of cement has an important bearing on the rate of hydration and hence on the rate of gain of strength and also on the rate of evolution of heat Finer cement offers a ,...

  • Exp 3 Sieve Analysis

    The information obtained from fineness modulus is helpful in the following ways; Sieve Analysis 1- Fineness modulus tells us directly whether the material is well-graded or gap-graded 2- Fineness modulus gives us an overall idea whether the material is fine or coarse Higher the value of FM ,coarser will be the aggregate...

  • THE ROLE OF FINENESS MODULUS

    Jul 20, 2018· Fineness modulus also provides important information about the density of the resulting concrete, as well as its compressive strength Both of these factors must be taken into consideration when designing the concrete For more information about the role played by fineness modulus, contact the concrete experts at Southport Concrete Corp...

  • Fineness Modulus of Aggregates: The Inside Scoop

    How Fineness Modulus Affects Concrete Mix In a nutshell, fineness modulus describes the gradation curve as well as the texture and uniformity of the material A lower FM factor means that the aggregate particles in that sample are finer on average FM of the fine aggregate fraction is also an important predictor of other characteristics of ....

  • Fineness of Cement

    The size of the particles of the cement is its finenessThe required fineness of good cement is achieved through grinding the clinker in the last step of cement production processAs hydration rate of cement is directly related to the cement particle size, fineness of cement is very important...

  • What Is Fineness Modulus of Sand?

    Aug 14, 2019· Fineness modulus of aggregate is an index number which gives an idea about the finance of aggregate and is an approximate proportion of the average size of particle in the aggregate It is found out by sieve analysis test of standard size in the laboratory The thumb rule is lower the fineness modulus, particles are smaller and higher the fineness modulus, particles are larger...

  • Fineness Modulus

    343 Fineness Modulus The significance of fineness modulus (FM) is in specifying the proportions of fine and coarse aggregates when designing concrete mix The higher the value of FM, the coarser the aggregate Generally, a lower FM results in more paste, making the concrete easier to finish...

  • ACI Mix Design Example

    Water-Cement Ratio Since the specified strength is flexural strength, a conversion factor must be used to obtain an approximate compressive strength in order to use the water-cement ratio vs compressive strength tableA good rule-of-thumb (as used in the ACI Code) is:...

  • Aggregates for Concrete

    portland cement concrete in North America are gravels; most of the remainder are crushed ston Naturally occurring concrete aggregates are a mixture of rocks and minerals (see Table 5-1) A mineral is a natu-rally occurring solid substance with an orderly internal structure and a chemical composition that ranges within narrow limits...
