8 Properties

Question 1

What is compressive or crushing strength?

Answer 1

The ability of a material to resist forces that attempt to squeeze or compress the material together

Question 2

What is tensile strength?

Answer 2

Tensile strength is the flexibility of a material to breaking under tension

Question 3

What is workability or ease of placement?

Answer 3

• workability means the ease of placement and workable concrete means the concrete which can be placed and can be compacted easily without any segregation.
• Workability is a vital property of concrete and related with compaction as well as strength.

Question 4

What is particle size distribution?

Answer 4

The particle-size distribution (PSD) of a powder, or granular material, or particles dispersed in fluid, is a list of values or a mathematical function that defines the relative amount, typically by mass, of particles present according to size.

Question 5

What is density?

Answer 5

Density is the degree of compactness is a substance

Question 6

What is water content?

Answer 6

Water content is how much water is within or needed within a certain material to fulfill its intended use

Question 7

What is temperature susceptibility?

Answer 7

-Temperature susceptibility is a requirement of bitumen

The bitumen should not be highly temperature susceptible: during the hottest weather the mix should not become too soft or unstable, and during cold weather the mix should not become too brittle causing cracks. The viscosity of the bitumen at the time of mixing and compaction should be adequate

Question 8

What is young’s modulus

Answer 8

The bitumen should not be highly temperature susceptible: during the hottest weather the mix should not become too soft or unstable, and during cold weather the mix should not become too brittle causing cracks. The viscosity of the bitumen at the time of mixing and compaction should be adequate
