The purpose of the fine aggregate is to fill the voids in the coarse aggregate and to act as a workability agent. >> Partially Crushed Gravel or Stone – it is a product of the blending of the above two aggregate. stream the size range of various coarse aggregates given below. Usually, the bulk density values for fine or coarse aggregate is in the range of 1350 to 1650 kg per meter cube. Coarse aggregate: Size: Fine gravel. 0000023550 00000 n 1.2 Units—The values stated in SI units are to be regarded as standard.

However, Table 1 is waived for those aggregates intended for usage in bituminous mixtures, provided the material is graded on sieves specified in production requirements contained in 6-2.3, and meets uniformity and bituminous design requirements. Following are the classification of aggregates based on size: Aggregates are classified into 2 types according to size. >> This care is not only applicable to parent rock but also to the crushing machine used. 4 No. Aggregate Size Chart Uae Grinding Mill China. endobj In what case is a Shear Key provided in Foundation? 2.1.2 Crushed Stone Sand - Fine aggregate produced by crushing hard stone. to No.4 (1 in., % in., 1/2 in., % in., and No.4) The sieving results (i.e. The numbered sieves refer to the number of square openings per inch (25.4 mm-so a #4 sieve has 1/4-inch (4.75-mm) square openings; a #16 has 1/16-inch (1.18-mm) square openings. According to sources of coarse aggregates, it can be further classified as: (a) Uncrushed Gravel or Stone: It results from natural disintegration of rock. >> Irregular aggregates may result 35- 37% of voids. Aggregates occupy 70 to 80 % of total volume of concrete. << So, we should take care about the shape of aggregate. /O 25 Air cooled blast furnace slag fine aggregate 2.6 Granulated blast furnace slag fine aggregate 2.1 Steel furnace slag, both fine and coarse 3.2 Gravel Coarse Aggregates There is a specific requirement for gravel coarse aggregates regarding crushed particles. These will give lesser workability when compared to rounded aggregates. Stone number is defined by the amount of an aggregate that will pass through specific sieves by mass percent. 0000046880 00000 n Natural sand is generally used as fine aggregate, silt and clay are also come under this category. Coarse aggregate may be available in several different size groups, such as 19 to 4.75 mm (3/4 in. increases with an increase in coarse aggregate size. /O The 13 standard sieves for coarse aggregate have openings ranging from 1.18 mm to 100 mm (0.046 in. /Font << /F1 29 0 R /F2 33 0 R /F3 37 0 R /F4 40 0 R /F5 45 0 R /F6 48 0 R When the aggregate is sieved through 4.75mm sieve, the aggregate passed through it called as fine aggregate. /L 64021 0000023832 00000 n /S 134 0000047372 00000 n Next, the required minimum percentage passing D is given, followed (for coarse aggregates only) by the maximum percentage allowed to pass d.
