Granite. Types of granite. Geologically, the granite includes/understands
essentially to igneous rocks of granular texture composed of feldspar and
quartz. A rock is considered dimensionable; therefore it can be cut and polished
to dimensions and forms you specify. He is superior to the marble in hardness,
resistance to the wearing down, the corrosion and the application of compressive
stress. In commercial terms, the granite includes/understands to feldespáticas
rocks and can include sienita, gabro, anortosita and other rocks. Each one of
these has own characteristics, to which the following common commercial
requirements and have greater relevance referred generally to plates are added
to him and parquet. Constant thickness with a tolerance of + - 1/32", it squares
perfect, brightness mirror, without porosity, homogenous beveling.
Classification of the granite: quartz, feldspar, and micaceos. This depends on,
as it is the mineral that it has in greater composition. Characteristics of the
granite: he is totally crystalline, extraordinary resistance, totally natural
origin, noble aging, is not possible to be fixed on any support, it offers
isolation against the humidity, the changes of temperature and the aquatic
contamination. The bordered one resists, the wearing down and outdoors, the
little porous surface, facilitates its cleaning. The betas are like small dotty.
Main Uses: Construction: It is used like material for construction, in the
covering of facades and architecture in general, as well as the elaboration of
structures such as bridges, retaining walls and jetties in ports. Also it is
used to construct curtains of prey and as material base in the road
construction. Ornaments: It is used like material to elaborate ornamentals
figures and monuments. Manufactures: In the manufacture of cylinders to grind
pulp in mills of the industry wastebasket. |
