Aggregate Size Effects: • As the maximum size aggregate increases, the amount of paste needed for a given slump decreases. • The maximum aggregate size used in a concrete mix is dictated by the size of the structural member and the spacing between reinforcing steel.

Road Aggregate 101: Nominal maximum and/or minimum sized stone in mix The nominal size distribution of an aggregate specification is defined as the range of sieve openings through which of the aggregate can pass. Road Aggregate 101: Gradation or distribution of different sized stones Open graded aggregate vs. well graded aggregate.
Tables 1 through 8 list concrete masonry wall weights for 4 to 16 inch (102 to 406 mm) thick single wythe walls. Wall weights for grouted 4-in. (102-mm) concrete masonry walls are not provided. Because of the small core size and resulting difficulty in consolidating grout, these units are rarely grouted.
7. Estimation of coarse aggregate content- The percent of coarse aggregate to concrete for a given maximum size and fineness modulus is given by Table 4. The value from the table multiplied by the dry-rodded unit weight (the oven-dry (OD) weight of coarse aggregate required per cubic foot of concrete).
1 cubic meter 20 mm aggregate weight in Kg. Aggregate are used in Building, Bridge, dams Construction aggregate, or simply aggregate, is a broad category of coarse- to medium-grained particulate material used in construction, including sand, gravel, crushed stone, slag, recycled concrete and geosynthetic aggregates. Aggregates are the most mined materials in the world.
The purpose of this research was to determine the effects of aggregate size and gradation on the unit weight, strength, porosity, and permeability of pervious concrete mixtures. The water-cement ratio (w/c) and cement-aggregate ratio (c/a) were kept constant at 0.29 and 0.22, respectively, with a design unit weight of 2002 kg/m3 (125 lb/ft3).

The Unit weight or bulk density of aggregate is the mass or weight of the aggregate required to fill a container of a specified unit volume. The approximate unit weight of aggregate that is commonly used in normal concrete work is between 1200-1750 kg/m 3 (75-110 lb/ft 3 ).
The additional filler may be composed of sand, but the amount of sand shall not exceed 20 percent by weight of the total combined base aggregate. All the sand shall pass a No. 4 mesh (0.45 mm) sieve and not more than 5 percent by weight shall pass a No. 200 mesh (4.75 mm) sieve. CONSTRUCTION METHODS 208–3.1 OPERATIONS IN PITS AND QUARRIES ...
Aggregate is classified as two different types, coarse and fine. Coarse aggregate is usually greater than 4.75 mm (retained on a No. 4 sieve), while fine aggregate is less than 4.75 mm (passing the No. 4 sieve). The compressive aggregate strength is an important factor in the selection of aggregate.

As specific gravity is just a comparison, it can be applied across any units. The density of pure water is also 62.4 lbs/cu.ft (pounds per cubic foot) and if we know that ammonium nitrate has a sg of 0.73 then we can calculate that its density is 0.73 x 62.4 = 45.552 lbs/cu.ft. Note, kg/cu.m divided by 16.02 = lbs/cu.ft
Key Features: If the volume is unit then, Bulk Density= Mass. Unit in kg/m 3 or lb/ft 3. In this definition, the volume is that contains both the aggregates and the voids between aggregates particles. The approximate bulk density of aggregate that is commonly used in normal-weight concrete is between 1200-1750 kg/m3 (75-110 lb/ft3) .
Changes in gradation, maximum size, unit weight, and moisture content can all alter the character and performance of your concrete mix. Economy is another reason for thoughtful aggregate selection. You can often save money by selecting the maximum allowable aggregate size.
The graded coarse aggregate is defined by its nominal size i.e., 40 mm, 20 mm, 16 mm, 12.5 mm, etc. For example, a graded aggregate of nominal size 12.5 mm means an aggregate most of which passes the 12.5 mm IS Sieve.

1. Obtain a sample of coarse aggregate material retained on the No. 4 (4.75 mm) sieve (Figure 6). This sample size is based on nominal maximum aggregate size (NMAS). Sample sizes range from 2000 g for a 0.5 inch (12.5 mm) NMAS to 5000 g for a 1.5 inch (37.5 mm) NMAS. Figure 6: No. 4 (4.75 mm) sieve. 2. Prepare the material.

T 27). The range of particle sizes in aggregate is illustrated in Fig. 5-4. The aggregate particle size is determined by using wire-mesh sieves with square openings. The seven standard ASTM C 33 (AASHTO M 6/M 80) sieves for fine aggregate have openings ranging from 150 µm to 9.5 mm (No. 100 sieve to . 3 ⁄ 8. in.). The 13 standard sieves for ...
The graded coarse aggregate is defined by its nominal size i.e., 40 mm, 20 mm, 16 mm, 12.5 mm, etc. For example, a graded aggregate of nominal size 12.5 mm means an aggregate most of which passes the 12.5 mm IS Sieve. Because the aggregates are formed due to natural disintegration of rocks or by the artificial crushing of rock or gravel, they ...

The weight of the aggregate is measured and divided by the volume of the container to yield the dry rodded unit weight in terms of weight per volume such as pounds per cubic foot. By knowing the dry rodded unit weight of a nominal maximum size coarse aggregate and the fineness modulus of the fine aggregate, the

ASTM C 33 ("Standard Specifications for Concrete Aggre-gates") lists several such size groups using the simplified practice recommendation (SPR) number designation. The number and size of sieves selected for a sieve analysis depends
Dry-rodded unit weight: Dry-rodded unit weight is the mass (weight) of one cubic meter (foot) of dry coarse aggregate that is compacted, by rodding in three equal layers, in a standard container. For any one aggregate the dry-rodded unit weight varies with the size and gradation.
