This marble is a dolomitized limestone.
Macroscopic Description: This marble is a fine grain limestone, with various tones of brown colouring and white veins.
Mineral Composition: Calcita, Dolomite. Clay minerals.
Microscopic Description: Accumulation of Pellets in a sparitic matrix.
In the paving is particularly important chemistry (especially indoors), impact resistance and wear resistance.
The same goes for the stairs, and add a new requirement, resistance to bending as the placement of the pieces. Moreover, we must distinguish between placement on the outside and inside. The place abroad poses new requirements for resistance to thermal shock and frost and therefore absorption.
In addition, we must not only consider whether their use is outdoors or indoors, but the kind of environment that we're going to find. There are outdoor environments contaminated or near the sea. In the first case will become more relevant chemical resistance of the material. In the second, resistance to salt attack.
If the use will be indoors, there may be wetlands due to the presence of groundwater, water leaks, etc. In this case you must take into account the water absorption, capillarity and resistance to salt water contained in the material.
But there are features that must be taken into account regardless of their use, which are those related to the durability and appearance of the material.
Given all these conditions we recommend the use of material, so as to present a proper appearance at all times to stay put and have a longer life.
In addition to the features that are influenced by the use, you must take into account the thickness required in each case to prevent a deterioration of the material breaks, unable to withstand an impact, compression or bending.
