Granite Pavers - All you need to know

Granite is the most common & used natural stone available in quarries across the world. Since the ancient days of human history, we are using granite as a favorite construction rock for indoor and outdoor applications. Thereby, everyone has some interests to explore more about Granite Rocks.

Origin of Granite:

Granite has a felsic composition. It means it has origin in recent geologic time, so it found in upper strata of the earth. Mafic and ultramafic rocks are denser than granite and found beneath the granite layer in a mental crust of the earth.
Geochemically, granites have fractional crystallization, so they are rich in feldspar (Potassium) and quartz (Silica) as primary components. Based on the origin when granite derived from melted sediments (Sedimentation-origin) those are rich in alkali feldspar, whereas, granite formed from melted basalt (Igneous-origin) those are rich in plagioclase feldspar. Moreover, granite formation is mostly based on the slow cooling process, so it has larger crystals.

Properties of Granite:

Due to an abundance of grains or coarse-grained nature, we know these ingenious rocks as granites. Granites used to contains 20% to 60% quartz by volume, and average 35% feldspar rich in alkalis. Apart from quartz and feldspar, these rocks also consist of mica and amphibole minerals.

Why Granite the Best Natural Stone Pavers for Patio-like Outdoor Applications in 2019

Apart from physical properties, certain commercial characteristics render granites as the best paving material when you have chosen natural rocks as the indoor and outdoor construction projects. Let’s check some of the most important properties.
