What is the water absorption of Giallo Siena marble?
0.04 per cent to 0.12 per cent, published to EN 13755-08.
Answer
What is the compressive strength of Giallo Siena marble?
The published figures
89.4 to 175 MPa, published to EN 1926-07, and the two published clusters differ by almost a factor of two. Both are stated here rather than one being chosen, because a specification drawn from either has to name which one it follows.
The figures
| Property | Value | Source |
|---|---|---|
| Compressive strength | 89.4 MPa ± 19.9 | Published technical sheet [S1] |
| Compressive strength | 163–175 MPa | StoneContact / Politecnico di Torino [S6] |
| Open porosity | 0.30% mean, 0.30 standard deviation | EN 1936-07, published technical sheet |
| Apparent density | 2710 kg/m³ (both published sources agree) | EN 1936-07 |
Why this stone behaves this way
Compressive strength is what decides whether a stone can be used as a floor at all, and on this stone the published figure is high. The disagreement between the two sources is stated because a buyer comparing two specification sheets has to know that a factor of two is on the table.
What these figures are, and what they are not These are published values for the material, not a certificate for the slab being supplied. A certificate issued for the block governs, and it is worth more than a table on a website.
Where these figures come from
- S1 granitalsiena.com — Giallo Siena marble technical sheet (EN standard test values; Politecnico di Torino marble laboratory)
- S6 StoneContact — Giallo Siena Unito and Broccatello di Siena entries, carrying Università di Pisa - Politecnico di Torino test values for the material
