What are 4 types of structures (load bearing systems) of buildings?

Frame, Shell, Mass, Combined

Name 5 timber products used as building materials.

Plywood, Laminated Veneer Lumber (LVL), Glulam, Particleboard, Oriented Strand Board (OSB)

Define binder (binding material). Name 2 types of binding materials depending on the binding mechanism and explain the difference between them.

A binder is a substance that holds or binds other materials together. Two types of binding materials are hydraulic binders (e.g. cement) and non-hydraulic binders (e.g. lime). The difference lies in their ability to set and harden in the presence of water.

What is reinforced concrete? Describe the advantages over plain concrete.

Reinforced concrete is concrete in which steel reinforcement is embedded. Its advantages over plain concrete include increased tensile strength, improved resistance to cracking, and enhanced durability. Signup and view all the answers

What is the most important property of hardened concrete? What is the most important property of fresh/liquid concrete? Why are they important? What shapes of samples are allowed for mechanical tests of concrete? Name 5 hazards to the durability of concrete.

The most important property of hardened concrete is compressive strength, while workability is crucial for fresh/liquid concrete. Compressive strength is crucial for structural integrity, and workability affects the ease of handling and placing concrete. Cubes, cylinders, and prisms are allowed shapes for mechanical tests. Hazards to the durability of concrete include chemical attack, freeze-thaw cycles, abrasion, alkali-aggregate reaction, and corrosion of reinforcement. Signup and view all the answers

What is the purpose of concrete cover and what factors are considered for its design?

The purpose of concrete cover is to protect the reinforcing steel from corrosion and fire, and factors considered for its design include environmental conditions, exposure to aggressive substances, and structural requirements. Signup and view all the answers

How do you ensure the appropriate thickness of concrete cover on a construction site?

Where do you place reinforcing in a simple beam under load?

Reinforcing is placed at the bottom of the beam, where it experiences tension during loading. Signup and view all the answers

Define plastics and how are they divided? What are the properties of plastics?

Plastics are synthetic materials made from polymers and are divided into thermoplastics and thermosetting plastics. Some properties of plastics include low density, resistance to corrosion, and electrical insulation. Signup and view all the answers

What types of soil do we distinguish based on grain size? How do you test for grain size?

Soil is distinguished based on grain size into gravel, sand, silt, and clay. Grain size is tested using methods such as sieve analysis and hydrometer analysis. Signup and view all the answers

What is the difference between shallow and deep foundations?

Shallow foundations transfer loads to the soil near the surface, while deep foundations transfer loads to deeper, more competent soil or rock layers. Signup and view all the answers

Name and describe two kinds of pile foundations.

Two kinds of pile foundations are friction piles and end-bearing piles. Friction piles transfer loads to the soil along the sides of the pile, while end-bearing piles transfer loads to a firm stratum at the bottom. Signup and view all the answers

Name 4 types of walls depending on their function.

The types of walls depending on their function include retaining walls, sound barriers, load-bearing walls, and partition walls. Signup and view all the answers

What is a partition wall and how does it differ from a load-bearing wall?

A partition wall is a non-load-bearing wall that divides the interior space, while a load-bearing wall supports the structure's vertical loads. Signup and view all the answers

What is a curtain wall? What are the functions of a roof? Name and sketch 4 different types of roof shapes.

A curtain wall is an exterior wall that does not support the load of the building. The functions of a roof include protection from weather, insulation, and supporting equipment. Four types of roof shapes are gable, hip, mansard, and flat. Signup and view all the answers

Name 3 types of insulation used in civil engineering. List possible causes of problems with moisture in buildings.

Three types of insulation used in civil engineering are thermal insulation, acoustic insulation, and moisture insulation. Possible causes of problems with moisture in buildings include leaks, condensation, and inadequate ventilation. Signup and view all the answers

Why do we provide obligatory thermal insulation? Define thermal bridging and give an example.

Obligatory thermal insulation is provided to reduce heat transfer, improve energy efficiency, and maintain indoor comfort. Thermal bridging occurs when a conductive material creates a path for heat flow through an insulated assembly, for example, metal studs in a wall assembly. Signup and view all the answers
