Limestone Aggregate Production
Limestone is an important source of construction aggregate due to its strength, versatility, and low thermal expansion. At Melgaard Construction, we own and operate limestone quarries and perform our own crushing and grading to achieve the ideal aggregate mix in the quantity required for all our projects, assuring a steady supply of raw materials and a project that moves forward on-time and on- budget. In addition to providing for our own needs, we also produce surplus aggregate that we provide to construction projects anywhere in Montana, Wyoming, or North Dakota.
Benefits Of A Reliable Limestone Aggregate Source
The availability of local limestone varies greatly throughout the tristate region. Small deposits naturally occur in parts of Wyoming, but is not available at all within the state of North Dakota. One of the benefits Melgaard Construction enjoys is access to our own limestone mines, where we can produce, grade, and transport aggregate to any of our construction sites without the need for third-party sources or middlemen. This keeps the cost of production low and the projects running on-schedule.
Another benefit of our limestone mines is our agility is producing aggregate of a grade. Since all our aggregate is crushed and graded in-house, we can quickly and easily ramp up production of a grade or group of grades per our current project requirements. This ensures that we are never short-handed and that you never settle for second-best.
Limestone In Construction
Limestone is extremely versatile due to its unique characteristics, particularly when compared to other locally-available aggregates, such as clinker (“scoria”) and alluvial gravel. Specifically, limestone aggregates are desirable because they:
- combine strength and usability – limestone is much more durable than scoria, but easier to cut than silica-rich alluvial gravel.
- create a superior concrete – limestone bonds more tightly to the cement and is lighter-weight than gravel.
- encourage proper drainage – limestone’s permeability allows water to maintain its natural course, while discouraging erosion.
- have a low to non-existant silica content – this reduces the risk of an alkali-silica reaction.
- have relatively low rate of thermal expansion – limestone’s resistance to expansion and contraction due to changes in temperature help it resist cracking and crumbling.
Limestone, therefore, is widely used in construction projects of all types, including:
Crushed rock is an essential component of concrete. While either gravel or limestone may be employed, limestone produces a stronger concrete that is less prone to expansion and that resists the chemical reactions that can sometimes occur with silica-based gravel that causes the concrete to fracture.
Hydrated lime – which is a powdery byproduct of limestone mixed with water – is an important addition to asphalt, which can help reduce cracking and stripping, either when used alone or in combination with other chemicals.
Limestone aggregate is often used as a road base, due to its strength and durability. It is equally useful when constructing major highways and minor access roads.
Limestone aggregate is useful as rock fill under concrete slabs that form the foundation for homes, business, utilities, bridges, and almost every other type of infrastructure.
Large grades of limestone can be used as rip rap along river edges to prevent erosion and other forms of aggregate help promote good drainage while blocking soil flow.
Lime helps stabilize poor soils by adding strength and reducing plasticity and soil swell. It can be used as temporary stabilization to strengthen the soil for construction vehicles during construction or as a long-term solution to weak and clay-rich earth.
