The impressive density of granite is 2.6-2.7 tons per cubic meter of volume. This is the strongest building material, which also has a high decorative value.
Withstanding enormous loads (compressive strength of about 300 Mpa), granite blocks are able to survive for centuries, only slightly losing their neat appearance.
Granite density is a gift of nature
Such a high density of granite is obtained due to the unique crystallization processes under high pressure and exposed temperatures. In different deposits we find granite massifs with different mineral composition, so we can use stone with different shades and patterns in construction and decorative finishing.
The most common color is a mixture of large pink or red—brown grains with dark gray or black, light gray. Pure gray granite rocks are quite common, multicolored ones are less common: with blue, green, yellow and other shades.
People paid attention to such an amazing building material in ancient times, constructing magnificent architectural complexes with granite columns and exquisite cladding. Many of them have stood the test of wars, floods, earthquakes and time itself, appearing before us in their greatness. It was this simple figure of 2600 — the density of granite in kg per m3 — that made this possible.
A little more surprising about the density of granite
The seemingly simple facts seem surprising:
Both plagioclases and feldspar can predominate in granite rock, but the density of granite remains almost unchanged.
With such a tight compression, a stone turned out that practically does not absorb moisture.
Only diamond, corundum and topaz can scratch the granite surface.
Granite deposits are quite common, and we have the opportunity to use this excellent building and cladding material in modern construction.
