Luserna stone paving.
The Luserna stone extracted in the area of Piedmont is widely used in construction because of its great brilliance, and versatility of use.
This rock of sedimentary origin is composed of granules as large as grains of sand, quartz is the most important component of this stones which makes it resistant to abrasion. The binder of these grains is called matrix, cement if crystallized, it may be composed of calcium carbonate, either in the form of calcite or aragonite, but there may also find traces of silica or iron oxide. The sandstone has a high slip resistance and resistance properties of the discrete changes and mechanical stress. Sandstone is consilgiata estenri but for environments with temperatures below 0 ° C. The sandstone can contain significant amounts of iron, which will allow the yellowing of the stone having been laid. The main use of this material is the flooring such as slabs, and curbs sidewalk, the use of building as slabs for balconies, steps, risers, jambs and lintels, and roofing.
