Uses for #2 Crushed Stone. This gravel is often used for paving walk or driveways, at it can be walked and driven on with relative ease. On the other hand in smaller size aggregates the surface area is increased which increases w/c ratio and lower strength is achieved. In order to minimize cracking, it is ideal to use a mix design containing aggregates ranging from natural sand, to 1-1/4" at an average of 18-22% of each size … These ¾ to 1 inch rocks resembles a golf ball and weigh 1.25 ton per cubic yard. The maximum size aggregate used may be dependent upon some conditions. Then it must be crushed to meet Florida’s Department of Transportation standards. A coarse aggregate is said to be graded with size number 57 if it is sieved through a set of sieves in the size range of 1 in. In general, 40mm size aggregate used for normal strengths and 20mm size is used for high strength concrete. Concrete Materials Product #201 SD Size #1 ASTM C-33 Size #57 . This data is obtained from the sieve analysis. Excellent for topdressing areas because it can be comfortably walked or driven on. Stones in AASHTO #57 blend are detected with a 1.5-inch sieve, which is why the #57 stone size is around 1 to 1.5 inches. 4. Concrete Materials Product #221 SD Size #1 SD Size #1A ASTM C-33 Size #57.

AASHTO #57 (2B’s) Size 1 1/2 Inch Topsize Description. By the CT 382 definition, the maximum aggregate size is 3/4" and the nominal maximum aggregate size is 1/2". for example a graded aggregate of nominal size 20 mm means an aggregate most of which passes 20 mm IS sieve. The advantage of small aggregate in the water-ratio strength relationship may or may not be sufficient to offset the effects of its higher mixing water demand. A recycled alternative to limestone, #57 Recycled Aggregate is more economical and perfect for site development, temporary roadways, or as a base for a new project. In the November 2011 version of CT 202, nominal maximum aggregate size is defined as "one sieve size larger than the first size to retain more than 10%." With the w/cm fixed, the larger the nominal maximum size of aggregates, the lower the cement content for a given consistency. 57 and/or No. 8 sieve) (9.5 to 2.36 mm). Size #57 is another of the more popular gravel sizes. It is also used as the primary raw aggregate in ready-mixed concrete and some blacktop mixes. The size of the aggregate bigger than 4.75 mm is considered as the coarse aggregate i.e. * For specific material requirements or questions about your project needs, please … We have used aggregate grading #67 (3/4") from ASTM C 33 in the past. Sizes and Designations ASTM, AASHTO & DOT products available.

Workable by hand. Common applications: Driveway Gravel RV Pads Drainage Control French Drains Walkways Concrete Mix Disclaimer Description. the size range of various coarse aggregates given below. There is much controversy concerning the effects of coarse aggregate size on concrete, principally about the effects on fracture energy. 3. However, Gettu and Available in limestone, and washed river gravel. No. After harvesting, aggregate is processed: crushed, screened, and washed to obtain proper cleanliness and gradation. A coarse aggregate, 57 stone may be processed from natural, solid, durable materials such as granite, gravel, limestone, and sandstone. * Gradation Numbers 5 and 57 are yard ballast materials. We're considering going to a larger size such as #57 (1") or 467 (1-1/2") to reduce shrinkage cracks in the 24 inch thick walls. Color: Tifton Pink (pink, light red, light purple) Shape: Angular/Cubical Size: US Sieve 1" to #4 Weight: Approx. The smallest sieve opening through which the entire amount of aggregate is permitted to pass is called the nominal maximum size. 1.2 Units—The values stated in SI units are to be regarded as standard. Old Pa # = The old Pennsylvania Department of Transportation reference to aggregate sizing. Crushed aggregate is produced by crushing quarry rock, boulders, cobbles, or large-size gravel. In general, 40mm size aggregate used for normal strengths and 20mm size is used for high strength concrete. For example, #1 aggregate is nominal size 3½ to l½ inches (90 to 37.5 mm). When the aggregate is sieved through 4.75mm sieve, the aggregate retained is called coarse aggregate. Sizes of #57 Stone range from 1 inch to 1/2 inch. to No.4 (1 in., % in., 1/2 in., % in., and No.4) The sieving results (i.e. • #57 Size: This material is one of the most popular sizes of rock for landscaping purposes. The process is complete once the stone has been crushed and screened to size. Gravel, cobble and boulders come under this category. Answer: Not sure Explanation: Many factors dictate aggregate size, including method of placement, regional availability of materials, admixtures etc. It appears that optimum maximum size, so far as strength is concerned, will vary for different aggregates, different cement factors, different test ages and probably other conditions. Size Class A: 3-5 Inches / Class B: 4-8 Inches Description. • Concrete aggregate • Asphalt aggregate • Drainage stone • Seal coat chips for roadways • Stone roads and driveways • Road base • Backfill. Also, it cannot be shoveled by hand, so a skid-steer loader or dozer will work well to put the rocks in the desired position. 2 material, industry provides criteria as noted in Table 3-5, below. Its size makes it useful for weight-bearing applications such as foundation beds and driveways. D x is the particle size at which x percent of the particles are finer. Coarse aggregate: Size: Fine gravel. Construction Aggregate. Between three-quarters and one inch in diameter, individual stones are about the size of a nickel or quarter. For example, for the aggregate meeting the specification limits shown below would have a maximum size of 37.5 mm (1-1/2 in.) Our field personnel have expressed concern over placement of a 1-1/2" maximum size aggregate with a 2 inch clear cover. Aggregate size #8 is nominal size 3/8 to 0.094 inch (No. About #57 Limestone Gravel #57 Stone is a crushed Limestone aggregate.

This particular size of gravel ranges in diameter from 3/4th of an inch (1.9 centimeters) to 1 inch (2.54 centimeters) in diameter. Mostly, it is used as a construction aggregate in asphalt and concrete for road and highway work with or without a binder. •Example: ASTM C33 requires that 100% of a # 57 coarse aggregate MUST pass the 1.5” sieve but 95 - 100% MAY pass the 1” sieve, therefore # 57 aggregate is considered to have a Maximum size of 1.5” and an Nominal Maximum size of 1”. Secondly, add number 57 limestone rocks on top of the base. This size resembles a lemon or grapefruit. Coarse gravel. A similar-sized material, called size #67, is often used as a fill for roadway beds and in the construction of slabs of concrete. Easily described as nickel to quarter size. It will not compact. 3. According to size coarse aggregate is described as graded aggregate of its nominal size i.e. 8mm – 16mm. DelDOT = Delaware Department of Transportation specifications, Section 813 - Grading Requirements and Section 821 -Graded Aggregates. Some research (Strange and Bryant 1979, Nallathambi, Karihaloo, and Heaton 1984) has shown that there is an increase in fracture toughness with an increase in aggregate size. There are also a few blended or graded aggregate sizes that combine the gradation of several aggregates. and a nominal maximum size of 25.0 mm (1 in). Partially Crushed Gravel or Stone– it is a product of the blending of the above two aggregate. 4mm – 8mm. Recycled concrete is a viable source of aggregate and has been satisfactorily used in granular subbases, soil-cement, and in new concrete. In general for strength upto 200 kg/cm 2 aggregates upto 40 mm may be used and for strength above 300 kg/cm 2 aggregate upto 20 mm may be used. = Stone can consist of up to 10% of this size * Each Stone gradation can contain up to 10% upper and lower grades and some fine material (sand).
