In case of manufactured sand with welldesigned screening system the required grading and fineness modulus ( to ) can be achieved consistently . It must be noted that properly graded aggregates can improve both fresh and hardened properties of concrete.
Apr 26, 2012· Sand divided to 3 zones as fine sand, medium sand and coarse sand and limits are given to each Fine sand Medium sand Coarse sand For sands having fineness modulus greater than is not suitable for making a good concrete.
Jan 1, 1996 The fineness of the sand plays an important role in the finishability of the concrete mix, and even small changes in fineness can affect finishing. The fineness modulus is a single parameter that describes the grading curve and can be useful in checking the uniformity of grading.
Based on the practical experience, the fineness modulus of fine aggregate should be between 2 to and of coarse aggregate between to 8. Usually, the Fineness modulus is calculated for fine aggregate rather than for coarse aggregate. Sieve Analysis of Soil Test. Designation: ASTM D421, D422. AASHTO T87, T88. Apparatus: 1. Set of sieves. 2.
Sep 12, 2017· Fineness of fine aggregate is related to term fineness modulus; most commonly sand. Fineness modulus is a measure to define fineness of aggregate precisely it defines coarseness or fineness of aggregate to be used in concrete. Get Price Fineness modulus .
How to Calculate Quantities of Cement, Sand and ... Happho. A simple yet more accurate method (DLBD method) of calculating cement, sand and aggregate for Nominal Concrete mix M15, M20, M25 and M30 grade Concrete
Fineness modulus of sand (fine aggregate) is an index number which represents mean size of particles in sand. Get Price And Support Online; fineness modulus of gold head sand. gold head aggregate fineness modulus ddsenterprises. fineness modulus of gold head sand Fineness Modulus 2 30 3 3 3 Coarse Aggregate The coarse aggregate used .
The Fineness Modulus (FM) is an index number which is roughly proportional to the average size of the particles in an aggregate sample. It is obtained by adding the cumulative. percentages coarser than each of the standard sieves used for segregating sand and dividing the cumulative percentage by 100.
Test results shown that when the fineness modulus of sand in ECC was, the midspan deflection and fracture toughness of ECC increased nearly times and 2 times that of ECC with the sand fineness modulus of, respectively.
Cement Fineness. The modulus of elasticity of concrete determined by sonic methods decreases as the fineness of the cement increases. 7. The fineness of cement influences the drying shrinkage of concrete. When the water content is increased because of fineness, the drying shrinkage is increased.

Exercise :: Concrete Technology Section 4. If fineness modulus of sand is, it is graded as.
AGGREGATE WAQTC AASHTO T 27/T 11 T27_T11_short Aggregate 416 October 2011. Fineness Modulus. Fineness Modulus (FM) is used in determining the degree of uniformity of the aggregate gradation in PCC mix designs. It is an empirical number relating to the fineness of the aggregate.
A comparison of three maximum size gradings of sandgravel and sandcrushed stone mixtures in concrete has revealed that for each type and size of coarse aggregate a constant value for fineness modulus will be obtained for any workable mixture from lean to rich, if the cement is included in the modulus figures.
Fineness modulus of sand (fine aggregate) is an index number which represents mean size of particles in sand It is calculated by performing sieve analysis Read More Effect of Fineness of Sand on the Cost and Properties of,
