What is Crushed Limestone?

Crushed limestone is a sedimentary rock composed primarily of calcium carbonate (CaCO3), formed over millions of years from the accumulation of shells, coral, and other marine organism fragments. It is quarried, crushed, and screened into various sizes to produce aggregates suitable for a wide range of applications. Its properties, such as good load-bearing capacity, drainage characteristics, and relatively low cost, make it a popular choice for construction and landscaping projects worldwide. The color typically ranges from off-white to gray, depending on the purity and presence of other minerals.

The quarrying process involves breaking down large sections of limestone rock into smaller pieces using heavy machinery. These pieces are then fed into crushers, which reduce them to the desired particle sizes. Following crushing, the material is passed through screens to separate it into different grades or sizes, ensuring consistency and suitability for specific uses. The purity of the limestone can vary; some deposits contain higher percentages of calcium carbonate, while others may include dolomite (calcium magnesium carbonate) or other impurities, affecting its suitability for certain applications, such as agriculture where high purity is often desired.

Types of Crushed Limestone Aggregates

Crushed limestone is available in various gradations, each suited for particular purposes. These gradations are typically defined by the maximum particle size and the distribution of smaller particles. Common types include:

• Limestone Dust/Screenings: This is the finest grade, consisting of particles typically passing through a No. 200 sieve (less than 0.075 mm). It’s often used as a filler material, for creating smooth surfaces, or mixed with larger aggregates to fill voids and improve compaction.
• 3/4 Inch Crushed Limestone: A popular all-purpose aggregate, this size is suitable for creating stable base layers for driveways, patios, and pathways. Its larger particle size allows for good drainage and compaction.
• Pea Gravel: Consisting of small, rounded or angular stones typically ranging from 3/8 inch to 3/4 inch, pea gravel is often used for decorative landscaping, drainage around foundations, or as a component in certain concrete mixes.
• Crushed Fines (e.g., 1/4 Inch): This grade consists of particles smaller than 1/4 inch, offering a finer texture than 3/4 inch aggregate but coarser than dust. It’s useful for pathways, decorative mulch, or as a bedding layer for pavers.

The specific grading available can vary significantly between suppliers. For projects in Bilbao, understanding the required particle size distribution is essential for selecting the appropriate product.

Uses of Crushed Limestone

Crushed limestone’s versatility makes it indispensable in numerous applications:

• Construction Base Material: It forms the foundation for roads, driveways, patios, and building foundations, providing a stable, load-bearing base that allows for good drainage.
