Fine sand fineness modulus is 2.2-1.6, the average particle size is 0.35-o.25mm. Medium sand fineness modulus is 3.0-2.3, the average particle size is 0.5-0.35mm. Coarse sand fineness modulus is 3.7-3.1, average particle size is bigger than o.5mm. Sand and gravel materials usually make periodic movements in various sieving machines.
Low quality fine aggregate, in itself, will cause no freeze-thaw deterioration of air-entrained concrete. The different fine ag gregates, however, did cause variations in mortar shrinkage and water requirement. Modulus of elasticity was found to be the most significant aggregate property affecting shrinkage.
Jan 01, 1994 The Importance of Fineness Modulus. In 1925, Duff Abrams introduced the concept of fineness modulus (FM) for estimating the proportions of fine and course aggregates in concrete mixtures. 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 aggregates passing 4.75 mm tyler sieve and retained on .075 mm sieve are classified as Fine Aggregate. Types of Fine Aggregate. Usually, sand, crushed stone, and crushed bricks are used as fine aggregate in concrete or pavement construction. Sand. Sand is an important engineering material. In concrete works, sand is used as a fine aggregate.
The sand used should be a well-graded mixture from coarser to fine grains, complying with the requirements of IS 383 Latest edition or equivalent. For plastering purposes, the fine sand used must not have a modulus less than 1.5 and white slits are preferred not less than 4 percent.
F.M of Ideal fine aggregate for concrete applications are in range of 2.6 to 2.9. Fine sand (lower F.M Value ) reduces the sand requirement in the total aggregate proportion. On the other hand, coarser sand will require higher sand in the total aggregate proportion to give a cohesive concrete mix consuming least cement.
Fineness Modulus Of Gold Head Sand - speedexams. Fineness modulus of gold head sand greenrevolutionorg.Fineness modulus for sand115 fineness modulus for sand by luke m snell and bryan castles 1 this stone was published in the proceedings of the 10th annual mongolian concrete conferencefor mix proportioning, fine sand would require cement and a greater tendency to.
Divided by 100 to arrive at the fineness modulus. For conventional concrete the fineness modulus of the fine aggregate should range from 2.3 to 3.1. A 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.
Range from0.1 to 0.6 .The fineness modulus obtained suggest that, the aggregates used had an approximately average sizes of 600 m and 12.5mm for fine and coarse aggregates respectively. Thus, the sand used was normal sand since it lies within Zone II of geological grading. Figure 5 Test of Cylindrical Specimen for Splitting Tensile Strength.
Manufactured sand is defined as the residue, tailing or other non-valuable material after the extraction and the processing of rocks to form fine particles less than 4.75mm. Use of manufactured sand as a fine aggregate in concrete and mortar draws serious attention of researchers and investigators.
