What is the main difference in the manufacturing process between steel and concrete?
What is the main difference in the manufacturing process between steel and concrete?
- Steel manufacturing focuses on the quality of connections between members, while concrete manufacturing focuses on the quality of cement.
- Steel is manufactured under controlled conditions in sophisticated plants, whereas concrete involves the purchase of raw materials and mix design. (correct)
- Steel is manufactured with predetermined properties, whereas concrete relies on the expertise of the contractor and supplier for its quality.
- Steel production involves the use of specified raw materials, while concrete production does not require specific raw materials.
What does the analogy 'Cement is to concrete what flour is to a cake' imply?
What does the analogy 'Cement is to concrete what flour is to a cake' imply?
- The mix design only determines the potential quality of concrete, similar to how a recipe determines the potential taste of a cake.
- The contractor's expertise determines the final quality of concrete, similar to how the baker's skills affect the taste of a cake. (correct)
- The raw materials like aggregates are crucial in determining concrete strength, similar to how various ingredients affect the taste of a cake.
- The quality of cement determines the strength of concrete, similar to how the quality of flour affects the taste of a cake.
What is the role of the contractor and supplier in determining the actual quality of concrete?
What is the role of the contractor and supplier in determining the actual quality of concrete?
- They ensure that only high-quality cement and aggregates are purchased for concrete production.
- They play a significant role in determining the actual quality of concrete in the finished structure. (correct)
- They determine the potential strength properties of concrete through mix design.
- They execute proper connections between individual concrete members.
