Live ChatThe Fineness Modulus of Sand is an index number that indicates the mean size of the sand particles. It is calculated by performing the sieve analysis test with standard IS sieves. The fineness modulus of sand ranges from 2.2 to 3.2. To find the fineness modulus of fine aggregate required IS sieve are sizes of 4.75mm. 2.36mm 1.18mm.0.6mm 0.3mm.
Live ChatThe fineness modulus value gives an idea of the mean size of the particles present in the aggregates. The object of finding the fineness value is to grade the aggregate for the most economical mix for the required strength and workability with minimum quantity of cement. If the tested aggregate gives higher fineness modulus means the mix will.
Live ChatThe river sand is used as fine aggregate conforming to the requirements of IS 383-1970 having specific gravity of 2.68 and fineness modulus of 2.52 has been used as fine aggregate for this study. 3.
Live ChatJul 20 2018 Fineness modulus offers a way to quantify the average size of the aggregate particles in the concrete mix. The size of the particles in turn will greatly affect how easily the concrete pours and spreads as well as its strength and durability once cured. If you would like to learn more about how to determine the best type of concrete for a.
Live ChatJan 01 2021 The other samples showed a water absorption percentage of 2.2-2.75. The water absorption decreases with increase in fineness modulus as seen from Fig. 6. The water absorption affects the durability property of the mix therefore a sand with less fineness modules is preferable.
Live ChatAn effects on concrete by replacement of sand as thermal power plant pond ash on properties such as compressive strength split tensile strength flexural strength and Modulus of Elasticity are studied. The natural sand was replaced with pond ash by 0 20 40 60 80 and 100 by weight at fixed water-cement ratio 0.48. Results shows.
Live ChatArtificial sand confirming to all four zones was having specific gravity of 2.76 also used to full replacement of natural sand. The fineness modulus of coarse aggregate natural sand and artificial sand was 7.81 5.18 and 4.62 respectively. The water absorption was 0.50 and 0.52 for coarse aggregate and natural sand respectively.
Live ChatFineness Modulus of Sand • The fineness modulus is calculated from the particle size distribution of the fine aggregate • Values for sand suitable for concrete should range between 2.3 and 3.1 • Values cant differ by more than 0.
Live ChatA higher fineness modulus represents a coarser material and a lower fineness modulus represents a finer material. Knowing the fineness modulus of aggregate gives you some indication of the amount of paste needed to make concrete using the aggregate. For instance sand with a low fineness modulus has more voids in it and more particle surface.

Live ChatJul 12 2021 Distinct from coarse sand fine sand concrete has good water retention low bleeding rate good workability and is not easy to segregate. 2. Influence of sand fineness modulus on concrete mix When the sand in production becomes finer the concrete slump will decrease and the construction become more difficult.
Live ChatIt has been established that the quantity of air increases from the lowest fineness modulus of sand and attains the peak value at fineness modulus F.M of about 2.5 and afterwards decreases sharply. The sand fraction of 300 and 150 micron has shown a marked effect on the quantity of air entrainment.
Live ChatSep 13 2013 The overall fineness of sand is given by factor called fineness modulus. Fineness Modulus is given by division of the summation of cumulative retained fractions for standard sieves up to 150-micron sieve size by 100. The fineness modulus of sand varies from 2.0 to 4.0; higher the FM coarser is the sand.
Live ChatThe water reducing agent and air-entraining agent produced by Subote New Materials Co. Ltd. Jiangsu China were used as admixtures. The water used for the test was ordinary tap water. The size of the gravel with continuous grading was 5~30 mm. The fine aggregate was river sand with a fineness modulus of 2.58.

Live ChatFeb 01 2001 Ideal and optimum fineness moduli are used in combination with the geometrical gradation of aggregates to establish the mix proportioning of mass concrete. The ideal and optimum fineness moduli are experimentally determined for each maximum size of aggregate MSA by making concrete mixtures with aggregates of different fineness modulus and.
Live ChatMaximum compressive strength was found 3.87 ksi for concrete having fineness modulus for fine and coarse aggregate as 3.0 and 7.5 respectively with mix ratio 124. Compressive strength of.
Live ChatSep 17 2020 Low cement content has the same effect as higher values of fineness modulus as lesser quantity of fine particles is available. Depth of placed concrete also effects the bleeding as deep sections of concrete bleed more than thinner sections due to increase of pressure with increase in depth.
Live Chatmaterial such as sand gravel crushed stone blast-furnace slag and lightweight aggregates that usually occupies approxi-mately 60 to 75 of the volume of concrete. Aggregate properties significantly affect the workability of plastic concrete and also the durability strength thermal properties and density of hardened concrete.
