Brick Types, Manufacturing, and Mortar Guide

Brick Types, Manufacturing, and Mortar

Brick Classification by Texture

  • Rough or Coarse Bricks: These bricks are made from unrefined earth, molded by hand, and fired in simple outdoor furnaces called anthills (piles of bricks covered with burning firewood).

Firing Degrees and Brick Quality

The firing degree determines the brick’s quality:

  • Escafilado: Holy brick
  • Recocho: Over-fired brick (best quality, deep red color, most used in construction)
  • Good Looking: Well-fired brick
  • Brown Porter: Under-fired brick
  • Fine

Electrical Transformation Centers: Components and Functionality

Electrical Transformation Centers (CT) provide the installation of transformers, reducing high to low tension, complemented by switchgear for precise work. Their function is to distribute electrical energy at different voltages while allowing connection to the line at any point.

CT Classification:

  • Feeding: (in a point and in step)
  • Property: (company-owned, subscriber/customer-owned)
  • Location: (outdoor or indoor)
  • Construction: (aerial, underground, conventional, prefabricated compact)

CT Feeding Types:

Earth’s Moon, Rotation, Translation, and Layers Explained

Our Satellite: The Moon

The Moon lights the Earth’s night sky and is the brightest celestial object after the Sun, as observed from Earth. Its radius is approximately 1238 km, about 0.27 times the Earth’s radius. Its mass is nearly eighty times lower than that of the Earth. Its rotation period is 27.3 days, and its orbital period is also 27.3 days.

Due to the relative positions of the Earth, Moon, and Sun, we observe the Moon in various phases: crescent, waning moon, full moon, and new moon.

Earth’
