Decorative Aggregates
Extracted from quarries, crushed and then calibrated, aggregates appear in a range of products, including gravel, broken gravel and sand. They have many uses.
Main functions of aggregates
Aggregates are fragments of rock measuring from 0.08 to 80 millimeters in diameter.
Examples of their uses include:
- Road and highway surfaces.
- Railway ballast.
- Fill material.
They can also be mixed with a binder - either cements to make concrete or tar to make asphalt - and used in the manufacture of houses, structures and bridges.
They Have 3 Main Functions
Aggregates are fragments of rock measuring from 0.08 to 80 millimeters in diameter.
Support
thanks to their strength. Research into high-performance concrete and bituminous concrete has shown that the strength limits of materials depend, in part, on the aggregates they contain. Aggregates make a vital contribution to the strength of materials.Filling
Aggregates make mixtures more compact, facilitating specific applications including drainage, weatherproofing and heat retention.Embellishment
Thanks to their aesthetic qualities. Sand gives surface treatments their brightness. Local chippings lend their specific colors to many different types of concrete and concrete products, including tinted and stained concrete, interlocking concrete paving, industrialized concrete slabs and panels, and road paving.An essential Resource...Ahead of water...
01France produces 400 million tons of aggregates each year. Aggregates accounts for 75% of the minerals quarried every year in the country.
02This is the equivalent of 7 tons per Frenchman per year, compared with1.5 tons of oil or 0.5 tons of iron. Aggregates have become the most consumed raw material in the world, JUST AHEAD OF WATER.
