Every small building material plays a huge role in construction. Aggregates like 10mm, 20mm, and 40mm crushed stones look very basic the first time you see them, but these crushed stones are very important. Aggregates are the integral part of concrete and flooring, used in road bases and also in drainage systems. Let’s explore this more.
What Are Aggregates?
Aggregates are crushed stones or gravel that are used in construction for strength, durability, and density in materials like concrete, asphalt, and mortar. They come in different sizes, and the selection of materials depends on what you are building.
At Istika Building Materials, we regularly get customers asking, “Which aggregate size is right for my construction?” or “Can I use 40mm aggregate for home foundations?” Good questions! And that’s exactly what we will answer here.
10 mm Aggregate
What is 10mm aggregate used for? 10 mm crushed stone is one of the smallest sizes used in construction. It’s smooth, tiny, and easy to mix.
Best uses:
Floor screeding
Thin concrete slabs
Decorative pathways
Block work or wall plastering
If you are working on home construction, small RCC structures, or any construction work that doesn’t require heavy construction materials, 10mm aggregate is usually the best choice.
It mixes well with cement and sand, giving a smooth surface and removing gaps or vacuums in the concrete mixture. It’s also smaller and simpler to use.
20mm Aggregate
This aggregate size is the most commonly used in India. Why? Because it offers a great balance between size and strength. 20mm aggregate has enough density to add strength to the structure and is still small enough to fill gaps efficiently.
Best uses:
Reinforced concrete (RCC)
Slabs, columns, and beams
Roads and flooring
Residential and commercial building foundations
Builders generally choose 20mm aggregates for concrete construction because it provides good bonding with cement and sets the mix strong and durable. At Istika Building Materials, the 20mm aggregate is always in demand for huge construction projects and other home construction.
40mm Aggregate
Need a solid foundation or load-bearing foundations? Then 40mm aggregate is your right choice.
Best uses:
Road construction base
Large footings
Railways ballast
Mass concrete works
This size doesn’t fit as tightly as 10mm or 20mm, but that’s exactly the point. It creates strong gaps that allow water to pass through, which is why it’s often used in roadbeds and foundations in rainy areas. You will regularly see 40mm aggregates used in development projects, but even for individual house foundations (especially in black cotton soil), it’s used in combination with other sizes.
Why Aggregate Size Matters
Using the wrong size of aggregate can mess up the strength, workability, and life of your construction. Too small? This might make the mixture too weak and smooth. Too large? May lead to gaps, less bonding with cement, and cracks over time. That’s why professional builders always choose the right size for the job, and online platforms like Istika help you do just that.

Pro Tip from Istika:
When mixing aggregates for a concrete mix, many experts use graded aggregates (a mix of 10mm + 20mm) for stronger bonding. This creates fewer gaps and results in better strength and longer-lasting concrete.
Final Thoughts
Whether you are building a small room extension, a villa, or even a commercial structure, knowing your aggregate sizes is crucial.
Here’s a quick recap:
10mm aggregate = flooring, plaster, lightweight concrete
20mm aggregate = RCC work, slabs, foundations
40mm aggregate = roads, drainage layers, mass concrete
