This specification defines the requirements for grading and quality of fine and coarse aggregate for use in concrete. Fine aggregate shall consist of natural sand, manufactured sand, or a combination thereof. Fine aggregate shall be free of injurious amounts of organic impurities.
Sand shall meet the requirements with respect to grading, source of sand, and absence of undesirable air entraining characteristics. Sieve analysis shall be performed by sieving the sand by hand or mechanically as prescribed. Results of the sieve analysis shall be reported as total percentage passing each sieve.
(c) Post-compaction Grading and Plasticity Index (PI) (i) Scale A Requirements for Post Compaction Grading and PI Testing. Where testing is specified in Clause 304.10(c) or (d) and Clause 304.12 requires it to be Scale A, all pavement layers shall be tested for post-compaction grading and PI at the frequency specified in Table 304.111.

14/4/2014· The manufactured sand has required gradation of fines, physical properties such as shape, smooth surface textures and consistency which makes it the best sand suitable for construction. These physical properties of sand provides greater strength to the concrete by reducing segregation, bleeding, honeycombing, voids and capillary.
02-09-2014· If the sand does not conform to grading limit as specified above, then by combining it with other sand we can get the desired grading. Reference. IS:2116-1980- Specification for sand
Manufactured sand (M-Sand) is a It does not have the presence of impurities such as clay, dust and silt coatings, increase water requirement as in the case of river sand which impair bond between cement paste and aggregate. Modern and imported machines are used to produce M-Sand to ensure required grading zone for the sand.
Therefore, to examine the grading of fine aggregates, the common procedure of sieve analysis shall be adopted by using the set of sieves as mentioned in the section of grading requirements table. Significance of Grading The particle size of fine aggregates (sand) substantially governs the properties of concrete mix such as workability, pumping
Manufactured sand is the product obtained by crushing stone, gravel, or air-cooled iron blast-furnace slag specially processed to ensure suitable gradation. Aggregate for use in masonry mortar shall be graded within the limits prescribed. The amount of deleterious substances in aggregate for masonry mortar, each determined on independent
Standard Method of Particle SizeAnalysis and Grading Sand Shape for Golf Course Putting Green Root Zone Mixes 1.Scope 1.1 This method covers the determination of particle size distribution of putting green root zone mixes. Particles larger than 0.05 mm (retained on a No. 270 sieve) are
This specification defines the requirements for grading and quality of fine and coarse aggregate for use in concrete. Fine aggregate shall consist of natural sand, manufactured sand, or a combination thereof. Fine aggregate shall be free of injurious amounts of organic impurities.
Pipe Sand/Utility Sand In many instances, manufactured sand is a great choice for use in piping and and other utility-based applications. Very fine sand materials are ideal for back filling pipes that have been laid, cables, trenches, retaining walls, etc. White or tan utility sand is ideal due to the contrast in color for quick identification when digging.
