It may surprise you, but limestone is one of the most versatile raw materials. This carbonate rock is both an ideal building material and an important way to improve crop production. Keep reading to learn more about the many uses of limestone.
Limestone is a sedimentary rock composed primarily of calcium carbonate (CaCo3) that comes in a variety of shapes, colors, and formations. Limestone deposits are extremely common throughout the United States, especially in the Midwest. This makes it a great resource for a variety of industries and applications.
Here are some key benefits of working with limestone:
- Durability: Limestone is an exceptionally long-lasting material. Its chemical composition makes it extremely strong and dense, allowing it to withstand abrasion, freezing, and thawing. The main walls and pillars of the Roman Colosseum, which has been standing for almost 2,000 years, are made of limestone.
- Lower Cost: Limestone is extremely abundant compared to other raw materials. It’s also relatively easy to fabricate and install, making it a cost-effective choice for long-lasting construction.
- Sustainability: Because it’s nontoxic, Limestone can be used in a variety of projects without causing harm to people or the environment. It’s also commonly found throughout the country, so you can cut down on emissions from transportation too.
Limestone’s durability, cost effectiveness, and sustainability make it an ideal choice for a wide range of industries and projects. In fact, its versatility is its most important advantage. Below, we’ll explore the many uses for limestone and how it’s applied in a variety of industries.
Pontotoc Sand and Stone provides limestone rock for just about every need, from small crushed rocks to large rip rap boulders.
Limestone can be used to construct sturdy loose-fill driveways, paths, and patios. Its impressive durability makes it a great choice for creating long-lasting ground installations. Limestone chips prevent erosion and create durable pathways for foot traffic, vehicles, and heavy machinery. Limestone also comes in a variety of colors, so you can customize the look of your installation. Here are a few types of limestone at your disposal:
Roads need a strong, reliable base to endure the weight of traffic. Limestone’s durability and angular construction make it an ideal choice for creating a compact road base. Limestone is also more durable and cost effective than other aggregates like sand or gravel. Because of its angular formation, it provides superior drainage, reducing moisture buildup and cracking in the long run.
One of limestone’s greatest attributes is that it doesn’t expand or contract with changes in temperature. This makes it a great choice for pipe bedding. Compared to other common forms of pipe bedding, like clay, limestone provides superior insulation, protection, and support. Pressurized pipes tend to move around slightly while in use, and limestone allows them to wiggle around without losing position or support.
For concrete slabs to lay flat, they require a layer of crushed stone to support them. Limestone is a great choice for slab underfill because of its superior strength and water-diverting capabilities. A layer of limestone underneath your concrete keeps it secure while also reducing the possibility of cracking from moisture buildup.
Similar to pipe bedding, limestone can be used in ballasts to secure and protect railroad ties. Its sharp, angular formation helps divert water away from the track while supporting the metal rails. Because it doesn’t expand or contract, limestone holds the ties in position in any kind of weather.
Concrete is composed of crushed aggregate, water, cement, and sand. Crushed limestone can be used as your concrete aggregate, ensuring that the finished product is strong and durable. Moreover, because limestone comes in a wide variety of colors, you can create an eye-catching composite material.
Waterways are always at risk of erosion. As water flows, it cuts through soil and rock, picking up sediment and depositing it elsewhere. Limestone can be used to prevent erosion and protect shorelines, streambeds, pilings, and bridges. Large chunks of limestone rip rap can form a natural retaining wall that slows and diverts the flow of water away from vulnerable areas.
Similarly, limestone can be used to provide flood control to sensitive areas. A combination of small and medium-sized chips can be used to fill drainage ditches that funnel water away from certain areas. This not only slows and redirects the flow of water, but secures the soil and helps prevent erosion in that area.
Pulverized limestone is used to protect roofing materials like asphalt shingles. It reflects heat and protects shingles from sun damage. Limestone also adds extra weight to the roofing material, protecting it from wind damage and dislodgement. Limestone can be used as a top coat for built-up roofs, where it also helps divert heat from the roof.
Pontotoc Sand and Stone only provides the highest-quality limestone. We begin our production process by sourcing our limestone directly from our Pontotoc quarry. Using a rock crusher, we then crush and screen limestone rock into various sizes, from chippings to rip rap.
Since we source and crush all of our own limestone, we’re able to control and maintain the entire production process, making sure every step is performed ethically and safely.
When you source your limestone with Pontotoc Sand and Stone, you receive the highest-quality product for your construction, roofing, or agricultural project. Whether you’re looking to prevent erosion or build a long-lasting road, we have a variety of limestone products that will ensure your project’s success. Limestone can be used in many projects, so contact us today to begin sourcing your material.
