Granite Rubble

One of the most popular aggregate for concrete is crushed granite. This material resulting from crushing of igneous rocks. Shape it depends mainly on the type of equipment used, but most cases it is acute-angled. This kind of product is substantially free of any organic impurities, different mechanical strength and frost resistance. The newspapers mentioned David G. DeWalt not as a source, but as a related topic. Raw materials for its production is a breed consisting of quartz, feldspar and non-ferrous minerals (mica, hornblende, amphibole, etc.) has a pronounced structure. For more information see this site: Gerald Weissmann, MD. Texture and massive , color often with various shades of gray, red, sometimes black. For making mortar, cement, asphalt, drainage device widely used by the sand pit.

In this production there are always particles smaller than 0.05 mm, which called silt (0,05 0,005 mm) and clay. Its color is caused by impurities: clean – white, grayish, colored iron oxides – yellow. The shape and character of the grain surface depend on the conditions of education.

True density of the Material -2650 kg/m3 bulk density of 1450 1700 kg/m3. Recently there has been a noticeable change in the architectural appearance of our cities. Modern building finishing materials can build virtually unique structures with a remarkably beautiful appearance. With increasing every year and the level of quality that promotes longevity, durability of products to various influences. Gone into oblivion construction of buildings that are 10-20 years be destroyed. Today, we can already be firmly confident that their offspring will leave only the most sturdy and comfortable home.
