Concrete Aggregate FAQs
What aggregate is best for concrete?
For general-purpose concrete, 20mm crushed gravel or limestone aggregate provides an excellent balance of strength and workability. Angular aggregates create stronger interlocking bonds within the concrete matrix, resulting in higher compressive strength than rounded aggregates. For exposed finishes or decorative work, smaller 10mm aggregates or speciality options like granite or coloured aggregates may be preferred, whilst for foundations and structural applications, larger 40mm aggregates can offer cost savings whilst maintaining necessary strength.
Do you need aggregates in concrete?
Yes, aggregates are an essential part of concrete, making up 60-80% of its volume and giving it structural strength, stability, and bulk. Without aggregates, concrete would just be cement paste, which would be incredibly expensive, prone to shrinkage and cracking, and have little in the way of compressive strength. Coarse and fine aggregates bound together with cement paste create a strong, durable composite – the versatile building material we know as concrete.
How much aggregate do you need for a cubic metre of concrete?
For a standard C20/25 concrete mix, you’ll need about 800-850kg (about 0.45-0.5 cubic metres) of aggregates per cubic metre of concrete. This usually needs around 400kg of coarse aggregate (gravel) and 400kg of fine aggregate (sand). Exact amounts may vary a little depending on the specific mix design, strength needed, and the size and type of aggregates used.
What are aggregates used
for in concrete?
Aggregates make up the bulk of concrete’s volume (typically 60-80%), giving it structural strength and stability while reducing the amount of cement needed. They create a rigid skeletal structure within the concrete that resists compressive forces and minimises shrinkage during curing. Additionally, the right aggregates will have a big impact on concrete’s workability, durability, and finished appearance, with different sizes and types used to achieve specific performance characteristics for various applications.
Can crushed concrete be used as an aggregate?
Yes, crushed concrete can be used as a recycled aggregate in new concrete mixes, such as for non-structural roles like footpaths, driveways, and as sub-base material. It typically comprises about 70-80% of natural aggregates with the rest being hardened cement paste and other materials from the original concrete. Using recycled concrete aggregate is more sustainable, as it reduces landfill waste and preserves natural resources, though it may produce concrete that is slightly weaker than mixes using virgin aggregates.
How much sand and aggregate
do you need for concrete?
For a standard 1:2:3 concrete mix (cement:sand), you’ll need around 425kg of sand and 700kg of coarse aggregate per cubic metre of concrete. This is roughly 0.25 cubic metres of sand and 0.40 cubic metres of coarse aggregate. The exact amounts may vary slightly depending on the strength and workability needed, and the specific characteristics of the materials being used.
