Seminar Questions

 

A: Water Proofing

2- What are the main factors to be controlled prior to the application of waterproofing materials? Explain each factor with reasons. 

Main Factors for Application:

 1. Elevation. 

 a.%1-3 elevation

 b. Enough number of water outlets for water discharge

 c. No ponding 

2. Surface 

a. Concrete / Screed (Strong, Dust-free, and Solid) 

b. Humidity (measured before the application and for product selection) 

3. Square meters (higher square meters increase the importance of crack bridging)

 a. 0 - 100 m2 (Cement – Acrylic - Polyurethane) 

b. 100 – 600 m2 (Acrylic - Polyurethane) 

c. Above 600 m2 (Polyurethane) 

d. Dilatation Detail (Should be studied separately)

 4. Purpose of Use

 a. Load Bearing (vehicle - load) 

b. Green Area

 c. Pedestrian Use or No Use Area

 3- What are the differences between waterproofing techniques done on the screed and over the screed? What type of materials can be used? How can they be applied? Explain the differences between these materials?

B: Thermal Insulation

1-      What are the advantages of thermal insulation materials? Explain your answer both ecologically and economically?

Advantages of thermal insulation materials:

1-      Energy efficiency, energy saving

2-      Stronger and longer-lasting building

3-      Positive effect on human-health

4-      Environment and ecological balance

5-      Helping sound insulation

6-      Support the family economy.

Ecologically

1-      Repair expenses reduced

2-      Protect building from outside factors

3-      Reducing building energy

4-      Reducing health expenses

 

Environmentally

1-      Has the greenhouse effect

2-      Min energy for heating, cooling.

3-      Reduce the consumption of fossil fuel

4-      Minimize the effect of fuel on environmental pollution without wasting energy.

 

5-      What is a cold bridge? How do you define it? At what locations of the building do this cold bridge can take place? Why? How do you prevent it?

       Cold Bridge is a movement of heat across an object that is more conductive than materials around.         Cold bridge one of the common reasons for energy loss in houses. It can be in the marble under the window. Even there is a heater under the marble, the marble will be cold anyway because the cold comes through inside from outside which is a cold bridge. It can be also a beam. Column or intersection of wall-floor and wall-roof. It can be prevented by using some materials. In this photo they used mortar between the two materials which can be a cold bridge if they used the same material as the wall, there will be no cold bridge.

Also covering the external walls with a continuous layer of thermal insulation like polystyrene insulation board can be used. In addition, mineral wool, insulated roof, and floor, rock wool can be used.
