To add to their land, they began to build rafts. The rafts were covered with the rich mud from the lake-bottom. They became floating gardens known as chinampa.
The materials that they often used were obsidian, copper, andesite, flint, wood, sidian and chert. Among the local building materials, Aztecs used wood and local soil in addition to a special kind of sun-dried brick called the adobe. These were the most commonly used materials for the construction of Aztec buildings.
Most simple Aztec homes were built of adobe bricks, which are made using mud, sand, water and straw, then dried in the sun.
The Aztecs used canoes as barges to move heavy building materials over long distances to their construction sites.
One area was where the family would sleep, generally on mats on the floor. Other areas included a cooking area, an eating area, and a place for shrines to the gods.
Early on in the history of the city the Aztecs built causeways and canals for transportation to and from the city. A causeway is a raised road that allowed the people to easily travel over the swampy and wet areas. … The canals acted like water roads that allowed people to easily travel around the large city in boats.
And without matches, wood was used in its simplest form to make the ultimate Aztec Boy Scout tool: fire kindling sticks (pic 4) that were rubbed together vigorously and at high speed.
Maya and Aztec builders used lime mortar as stucco or plaster, that could be painted on.
Each building and temple was built hand-by-hand and stone-by-stone. The masterpieces were the pyramid temples that had double staircases facing the sun on the west. Unlike the Egyptian pyramids, the Aztec pyramids were flat on top for sacrifices to be made to the god that the given temple was built for.
How did the Aztecs move building materials? They would pull the goods on the steaks as they rolled.
The Aztec civilization developed in the Valley of Mexico, wedged between high mountains and surrounded by lakes that provided fish, waterfowl, potable water and reeds for thatching and weaving. The climate was mild.
Mexica (Aztec) houses were simple, small and functional, to say the least, often with a single room, without windows. … The doorway provided the only source of daylight.
The Aztecs primarily relied on using aqueducts that transported spring water from the nearby hills into the city.
The Aztecs had indoor plumbing long before most Europeans did. … Most tribes didn’t need indoor plumbing because they didn’t live in cities mired in sewage, vermin, and disease.
One of the remarkable features of Aztec urban planning is the extent to which basic buildings and planning principles were standardized among cities throughout central Mexico.
Three innovations can be identified for Aztec cities.
The ancient Aztecs developed remarkable techniques of engineering and architecture to build causeways, palaces and pyramids. … They had concerts in front of the temples where the Aztec kings lived. They had libraries of painted scrolls. It was a beautiful and impressive site.”
With other uses, such as for tanning leather, the excrement was so valued that the city had a network of public latrines from which it was collected and eventually sold at the city’s main market. Human urine was used as a mordant (fixative) in the dyeing of fabrics, and, thus also considered a resource.
Agriculture is essential for civilization because it lets people live in one place, develop a surplus, and grow in population. Since they lived in the middle of a lake, the Aztecs built chinampas, long platforms of soil floating on shallow rafts, and grew their crops on these.
Aztec swords were made with rows of small obsidian teeth. They were murderous weapons for cutting an enemy. … Now we find that being cut with obsidian is less painful than you’d think, because it makes such a sharp edge. So obsidian became woven into Aztec worship as well as Aztec function.
Both Mayans and Aztecs then developed a technique that used thinner, mortared block walls filled with cast-in-place concrete, using a coarse limestone aggregate (basically, big gravel). … Despite the concrete, these colonial buildings are much more vulnerable to earthquake damage.
Concrete blocks, like the adobe that used to be used in both the US Southwest and México, insulates houses from hot temperatures outside. Unfortunately, they also keep the house cold in the wintertime.
