The Kroll Process is what? How is it different from manufacturing iron?

Cite three differences between hot working and cold working processed metal pieces.

(a) In general, which provides better fire performance, carbonate or silicate aggregates? Why? (b) Why does fire design incorporate a load reduction factor (Dfire) = 1.0? (c) Two identical beams (Beam 1 is simply supported, and Beam 2 is fully restrained) are heated under similar conditions. What does the mechanical strain equal to in each of these beams? (d) A design office located in Clemson, SC (with a branch in San Francisco, CA) envisions designing a new composite member made of steel and timber. This to-be designed member is expected to be used in wildfire-prone regions primarily for single family homes. Comment on how you would design such a member to achieve superior fire performance. (e) Plot and discuss the expected degradation faces in three bending elements (say, beams) to be made from concrete, steel and timber?

Discuss the basic process of manufacturing reinforcing steel.

give applications of the following materials:  GGBS, alkaline solution, Metakaolin, and Aggregates.

Puzzler: Most steel reinforcing bars manufactured in the U.S. exhibit a sharp yield plateau. Two exceptions, however, are bars that are quenched and tempered and bars that are coiled immediately after they are hot rolled. The coiled bars are later straightened by a fabricator. Both (1) quenched-and-tempered bars and (2) straightened bars have stress-strain curves that are initially linear, but yielding is gradual, producing what is described as a "round-house" curve. The reason for the round-house behavior is the same for both types of steel. Why do these two types of reinforcing steel exhibit gradual yielding rather than a sharp yield plateau even if the same steel exhibits a sharp yield plateau if it is not quenched and tempered or coiled?
