hapter 5. Solutions Beyond the Ordinary: Adaptations and Alternatives
5.1 Advantages and Adaptations of Mud and Stone
• The use of mud and stone is mainly due to affordability. They cannot manage construction completely without cement. They use it for the plinths and foundations. They have used lime wherever possible but over the years lime plaster has proven difficult to maintain.
This shows that it is practically impossible for them to construct purely out of mud and stone.
• What is interesting is the use of steel in combination with wattle and daub in Proto Village. In the dome house they have used a geodesic steel framework over which they have filled alternate triangles in with wattle and daub.
This concept can be taken even further and could possible lead to the construction of large span mud structures.
• The main problem they are facing is roofing materials. Thatch roofs are the most practical for this weather and budget but they also require a lot of maintenance. Another option would be to continue using aluminium sheeting but this will have to be insulated properly.
The roofing methods that are currently being used are

A layer of wire mesh is used over the galvanised iron sheet before laying the reinforcement of the framing beams which are welded to the J hooks used to anchor the sheets. This ensures that the concrete does not fill the valleys of the galvanized iron sheets and the air gap provides thermal insulation. The framing beams are then concreted to accommodate the infill material such as lean concrete or stabilized mud. This can then be clad with clay tiles, broken ceramic bars or slate depending on the availability of materials in the region. Effectively the concrete is used as a quilt over the internally secure waterproof diaphragm and assumes a secondary use. Galvalum sheets can be used in coastal regions where corrosion is a serious concern owing to
During the time they were building the Verbonia, they had to figure out what materials they were going to use and how they were going to get them. I know this because the text stated ¨the materials used most in the construction of the Verbonia were stone, clay, mortar, and wood. The stone came from a limestone quarry owned by
Steel frame structures are made as the name suggest from steel, the material is strong and flexible. When weight is added it bends without cracking. Another characteristic of steel is that its plasticity or ductility, meaning that when force is added it won’t crack however it will lose shape therefore giving warning for people to evacuate the building. A disadvantage of steel is that is loses strength when subject to fire. Studies have shown that it can loose up- to half its strength when subject to fire, therefore making it imperative to cover the steel with boards or spray on.
by hollowing out an existing rock, then covering it with a removable stone. The Monolithic Dolmens
Tomb is made of stone and brick instead of the usual shaft in the ground.
So long as mudbrick was properly shielded from the elements, it seems to be a more suitable building material than stone. One major issue with mudbrick, though, was its availability. Mudbrick could only be created with a specific clay that had such a consistency that it would adhere to itself when water was added. Also, a large amount of water was required to make mudbrick, and at some poleis, like Zagora, water was not easily accessible (Maher 35). Stone then was used as a substitute, and in order to increase strength stone was shaped to fit. Two styles of masonry emerged in lieu of mudbrick, Lesbian and polygonal. Lesbian masonry is defined by its primary characteristic, the joints are curved (Scranton 25). In order to ensure proper fit, “mason had strips of lead at hand, with which they made templates of the sides of each block when it had been set, so as to mark on the adjoining blocks the lines on which they should be cut to fit properly” (Scranton 27). Polygonal masonry, instead of cutting curved lines into the stone, cut the edges of the stone straight, typically resulting in blocks with 5 or more distinct
Some of the oldest known “Tegleproduction” brick production was found in I Tell Aswad, Syria where archeologists found brick rubble from around 7500 B.C, and in Jericho, north of the Dead Sea where foundations and ruins of a house from around the same time made of fired clay. Later the Egyptians and Romans became great users of brick in all aspects of building construction. Yes, there was use of natural stone especially in purpose built temples, palaces and pyramids, there is an Egyptian hieroglyph
The building is made up of crafted, recycled and locally sourced materials. This created an opportunity for artwork to be created within the architecture and interior. Rammed earth walls were mostly used to construct the building, alongside recycled wood, and concrete. The rammed earth walls were constructed using the earth from within the site and the wood was also locally sourced (Rinaldi,
Superstructure bears the load that is being passed over the bridge and it transmits the forces caused by the same to substructure. Load received from the decking is transferred on to the substructure by Bearings. They also distribute the load evenly over the substructure material as it may not have sufficient strength to bear the superstructure load directly. Piers and Abutments are the vertical substructures which transfer the load to the earth in the foundation. Wing walls and returns are constructed as the extension of
They have used two types of stone for the construction. All the bluestones for the construction are imported from places
Each building has its own concept which defines what kind of design it used. The roof design of the National Art Gallery adopted the combination of aluminium rainscreen cladding with curtain wall system. The following will briefly discuss on the system used:-
The lack of rain and an abundance of sunshine meant Egypt didn’t have fertile land for growing crops. Therefore, there was a low supply of wood to use for building houses. Every year, the Nile River flooded leaving mud behind. This natural resource was soon discovered as being the best choice for making bricks for homes. (“Ancient Egyptian Houses”) The mixture of sunbaked mud and straw made the strongest brick. Poor people only used one row of bricks, while the wealthy people used two or three rows of bricks to build larger dwellings. (“The Egyptians – Housing”) As long as they didn’t build where the Nile River flooded each year, these homes could stand for generations. The wealthiest people built their homes of real stone
A cofferdam is a temporary structure most likely consisting of steel structures welded together, with other parts consisting of sheet pile and sand braces. The cofferdam is usually broken down after the main work is done. The main cases in which cofferdams are used are a very large plan area of foundation, low water depths, soft soils in which sheet piles would easily be driven.
Evolution of the aluminium casting process since the 1960s empowers metal garden furniture industries to produce high-quality and sophisticated designs, at prices which are affordable for most of the households.
Gravel and stone mulches can be very effective, especially in gardens where organic mulches would be too expensive or impractical. They are generally better at retaining heat in cold climates, along with keeping valuable moisture in the garden soil. The disadvantages of using stone-based mulch is that it is heavy and difficult to remove, can be quite costly, and usually requires professional assistance to install the mulch in your garden. Here are a few tips on working with gravel or stone garden mulch. Gravel and stone garden mulch: Advantages Gravel and stone garden mulch is used to help the soil retain moisture and heat. If you live in a cold climate, stone mulch may work better to keep heat locked in because the pieces are larger than
Mud-brick became the building material of choice, being the primary material used for domestic architecture henceforth. Likewise, mud-brick became a standard medium for religious and funerary architecture. When compared to stone as a construction material, mud-brick presented many advantages. Unlike stone, mud-brick was universally available, it being possible to produce brick from Nile alluvium or desert sediments/clays, sand, and water-resources accessible to everyone, though in varying quantity [5, 6]. Mud-brick was quick to fabricate, especially when compared to the quarrying of stone blocks, and was therefore more economical, particularly for large construction projects such as entire palace complexes or row upon row of temple storage magazines [7]. 1.2 The City of Aswan Aswan is the ancient city of Swenet, which in antiquity was the frontier town of Ancient Egypt facing the south. Aswan is located about 879 km in the south of
