Limestone Grades

Differences in Limestone Grades

 

It can be intimidating to begin a limestone project. Depending on the size of the rocks you require, there are many grades of limestone to pick from. We’re here to walk you through your options for selecting a limestone grade. We use top-quality white limestone at Port Aggregates, which is as durable as grey limestone but weighs 10% less. This saves you money by allowing you to use less material to cover more space. You’ll also have the option of selecting a size range, which is where limestone gradations come into play.

 

The following variations are available in sizes ranging from 14” to 2”:

 

  • Calica #57 (34 – 1”)
  • Calica #89 (14 – 38”)
  • Calica #458 (58 – 2”)
  • Calica #610 (Powder – 12”)
  • Calica #689 (12 – 58”)
  • Kentucky (1 – 4”) is ranked 14th.
  • Kentucky is ranked fourth. (2–2 12”)
  • Kentucky is ranked #7 (38) in the country.
  • #8 (14”) Kentucky
  • Kentucky (#57, 34-1”)
  • Kentucky #610 (1 – 12”)
  • Crushed Concrete #610 (Powder – 12”)
  • Rip Rap 10lb
  • Rip Rap 30lb
  • Rip Rap 55lb

Crushed limestone works well as the top layer of a concrete driveway when mixed with aggregate concrete mixtures. Certain large grades, such as our #2 12 OG, can be covered with #57G and topped with a finer grade, such as #8G limestone, beneath the top layer. #8G crushed limestone can also be used as an aggregate for asphalt driveways, as part of a drainage system to run water off your property (38 – 12 inch), or as a decorative accent around plants and other natural components.

 

If you want a loose-top driveway, choose a larger, denser grade (up to 12 inches), such as our road gravel or crushed concrete. For the top of a levelled driveway, this is a low-maintenance option. Our larger grade rip rap (crushed limestone) #1x4G is perfect for preventing erosion on a hill, slope, or pond bank, and is often put over a textile. As bedding, a finer grade might be employed beneath this. Rip rap can also be used to create low-lying or plant dividing barriers.

 

Because of its finely crushed texture, pea gravel is commonly used for walkways and gardens. Crushed limestone in larger grades, such as #57G, is commonly utilised as a base layer for these walks or as a landscape filler to surround paving stones.

Crushed stone is a flexible commodity with a wide range of applications, from paver base material to landscape decoration. If you’ve ever worked with crushed stone, you’ve probably noticed that it comes in a variety of grades (sizes). These grades are based on the size of the stone after it has been crushed, and they tell you which uses the stone is most suited for. It’s vital to keep in mind that some gradations will have a variety of stone sizes within them. Individual stones ranging in size from 1” to 12” may be included in a CA11 or CA7 (usually 34”) gradation.

 

It’s helpful to understand the different grades of crushed stone when you’re out shopping. The following information will provide you a rough idea of what materials are available to help you choose the correct one for your project.

#1: Crushed stone  is the largest of the crushed stone grades, ranging from 2-4 inches in size. This material is ideal for bigger projects or filling in bigger holes.

Crushed stone

#3: Ranges in size from 1/2 to 2 inches. This material is ideal for railroad applications as well as those requiring drainage.

 

#5: Crushed stone This category covers stones with a diameter of one inch or less. This material is ideal for paver and road bases.

#8: Crushed stone This category contains stone that is 3/8” to 12” thick. This is the most widely used stone in concrete mixtures.

 

#10: Screenings or dust is a type of crushed stone #10. Pavers and concrete blocks are made from this material.

 

Crushed stone #57 is a 34” stone that has been crushed. Concrete mix, landscaping, and drainage are all examples of where this is used.

 

Crushed stone #67 is defined as stone with a diameter of 34 inches or less. This material is ideal for road and slab foundations, as well as fill.

Overview of 1/2′′, 1 1/2′′, and 3′′ Crushed Limestone

 

Crushed limestone is a calcium carbonate-based aggregate. The stone is mined and crushed to particular sizes before being utilised in a number of applications such as construction materials, drainage, concrete, backfill, and road bases.If you’ve ever worked with limestone, you’ve probably noticed that there are varying grades (sizes). These grades are used to determine the optimum stone for specific purposes and are based on the size of the stone after it has been crushed.
