What is Compressed Marble?

What is compressed marble?

Truthfully, a lot of people have seen compressed marble (also called agglomerated marble) – many have actually stepped upon it, especially for those who live in big cities. Many lucurious buildings use compressed marble as their floor material. But for the most part they only call it “marble”, when it is actually compressed marble.

So what is compressed marble? Why do so many fancy buildings use compressed marble as their flooring? The reason for this is because compressed marble is very elegant, to the point it makes the buildings using compressed marble seem as if they are extremely luxurious and have passed the level of natural marble. Compressed marble is produced by binding selected marble chips (93 to 95 %) with specially formulated resin (5 to 7 %).

The pictures below shows the difference between natural marble and compressed marble.

Natural marble - acquired from selected large rocks

This is the very basic step-by-step process of making compressed marble:

  1. Selected marble boulders are crushed and sieved into various sizes.
  2. Marble granules are mixed with specially formulated polyester resin and compacted under vacuum by vibro-compression technology.
  3. Large marble blocks are produced and cured for few days.
  4. Cured compressed marble blocks are sawn into slabs.
  5. Unpolished slabs are calibrated using digital automatic machine to ensure uniform size and thickness.
  6. Different stages of polishing are carried by automatic machines, the transformation process is closely similar to natural marble production.
  7. Cutting into required sizes by a laser machine to ensure dimensional accuracy.
  8. Final sorting, packing in cardboard boxes and stacking on wooden pallets before dispatch.

 

From this schematic you can clearly see how compressed marble is made:

Compressed marble (agglomerated marble) is made of the same materials and the whole body is homogeneous. Gentle grinding and polishing after installation make compressed marble surface smooth and shiny. This is an example of a floor that was installed with compressed marble.
