Module 4 Flashcards
1
Q
What is involve building construction?
A
- Finding, processing, transporting and assembling of material.
2
Q
Construction site importante?
A
- Determines the sustainability of a building to a high degree.
3
Q
Deconstruction?
A
- It is important that buildings are taken apart carefully to be able to recicle its materials
4
Q
Globalized construction?
A
- Construction used to be a localised activity,
but with the advancement of construction processes and construction materials, almost every building contains components of a globalised economy - Calculate the amount of CO2
5
Q
A probable construction material?
A
- They have embarked on the systematic rediscovery of bamboo as a building material in conjunction with concrete. Eventually, after processed in a way that makes bamboo more resilient with regard to water and decomposition
6
Q
Countries with highest urbanization rates?
A
- Subsaharan africa and southeast asia
- All developing countries
7
Q
What countries consume more cement and steel?
A
- 90% cement consumption 2011 from developing countries and emerging
- 70% of steel
- In africa 2 countries produce good amounts of steel the rest is imported. Colombia the same problem.
- Most developing countries have to import steel for construction, increasing their trade deficit
8
Q
Why it is not sustainable to build with steel in developing countries?
A
- Developing dont produce steel and have to import it with harms its economies
9
Q
Alternative construction materials?
A
- Advanced Fiber Composite Materials replacing steel and wood
- Constructing Waste for building
- Sand – Alternatives because that as a building resource is going to end
10
Q
What material should be used in developing countries for construction?
A
- Bamboo because the developing countries and countries with highest expected urbanization rates that grows there. In the equatorial region
- Bamboo can reach a tensile capacity than steel. Bamboo 820 MPa vs Steel 400 MPa
- Could cut construction material imports in these countries
11
Q
Other alternative construction materials?
A
- Straw put in a hot press, the starch contained within the homes act as a natural glue, it is used to build building panels. Is an agricultural by-product from cereal, rice crops
12
Q
Advantages of bamboo?
A
- High tensile capacity
- Grows faster than wood
- High capacity to capture carbon
- Lower country dependency in international markets
- Just some bamboo species have good properties
13
Q
Disadvantages of bamboo?
A
- Water absortion, swelling, shrinking behavior and limited durability
14
Q
Bamboo future?
A
- Using it as a composite material. Not as natural bamboo
