Limestone is a sedimentary rock mainly composed of calcium carbonate (CaCO₃), typically from the shells and skeletons of marine organisms like coral and mollusks.
Limestone forms over millions of years in shallow marine environments where shells, coral, and other calcium-rich organisms accumulate and compact into rock.
🛠️ Contractor insight: We often explain to clients that limestone is basically fossilized sea life — compacted over geological time into one of the most versatile rocks used in construction.
Limestone is used in:
Construction (base rock, concrete, asphalt)
Agriculture (soil conditioning)
Industry (steel making, cement)
Landscaping (decorative gravel, pavers)
📊 Common Limestone Uses Table:
Application Area | Use |
Construction | Base, roadstone, concrete mix |
Agriculture | Neutralize acidic soil (AgLime) |
Industrial | Smelting, cement, purification |
Landscaping | Paths, retaining walls, decor |
It usually appears light grey, beige, or white — often with small visible fossils. It's available crushed, in gravel form, or as cut stone blocks.
👷 At AggregateMarkets, we stock crushed limestone from pea gravel size to larger rip-rap for erosion control.
Yes, black limestone exists and is often used decoratively. It typically comes from different mineral impurities like carbon or organic matter.
Absolutely. When polished, limestone becomes smooth and elegant — used for flooring, countertops, and architectural cladding.
Yes, through a metamorphic process involving heat and pressure, limestone recrystallizes into marble over geological time.
Not plain water — but limestone can dissolve slowly in acidic rainwater due to its calcium carbonate content.
Limestone (as calcium carbonate) acts as a gentle abrasive to help scrub teeth clean and polish enamel.
🪥 Fun fact: If you brushed your teeth today, you probably used a little limestone.
It removes impurities from molten iron by forming slag, a byproduct that floats to the surface for easy removal.
Because it’s:
Abundant
Easy to shape and crush
Chemically reactive (for agriculture & industry)
Durable (ideal for roads and buildings)
Primarily calcite (CaCO₃). It can also contain small amounts of quartz, clay, and dolomite.
Mostly through surface quarrying, where the top layers of earth are removed and large limestone blocks are extracted and crushed.
🏗️ At AggregateMarkets.com, we partner with local quarries who follow strict safety and environmental standards when sourcing limestone.
Limestone is found in many U.S. states — especially Indiana, Kentucky, Tennessee, and Georgia. That’s why we’ve made it one of our most available products.
Allways go for bigger fractions like #1 or #2 as a base, medium stone like #53 or #73 for mid layer & smaller stone like #8 or #11 for top layer when building driveways. Limestone compacts well and provides a solid base.
📊 Driveway Limestone Comparison:
Product | Use | Features |
#53 Limestone | Driveway base | Mix of fines & stones |
Clean 3/4" Stone | Decorative top layer | No dust, clean look |
Yes — it's natural, recyclable, and abundant. Crushed limestone can even be reused or returned to the earth without harm.
Limestone raises the pH of acidic soils, which improves crop yield and nutrient absorption.
Yes, in most landscaping and driveway applications. Wash it down yourself or let the rain do it to remove the excess quarry dust.
