Control tests test I

Decide whether these statements are true or false:

1. a). Reinforced materials are embedded in the concrete to resist corrosion and consequently increase the life of the structure.

b). Reinforced materials are embedded in the concrete because such structures are light, have a long life, and are at times more economical.

c). Reinforced materials are embedded in the concrete in such a way that the two materials resist the applied forces together.

2. a). Plain concrete is not suitable for most construction projects because it requires a protective layer to resist corrosion.

b). Plain concrete is not suitable for most construction projects because it cannot easily withstand the stresses.

c). Plain concrete is not suitable for most construction projects because such a material can not be used for making any size and shape.

3. a). The main quality of reinforced concrete is similarity of its coefficient of thermal expansion with that of steel.

b). The main quality of reinforced concrete is enhancement of the structural tensile strength.

c). The main quality of reinforced concrete is enhancement of the structural compression strength.

4. a). On the hardening of the cement paste inside the concrete, it forms a strong bond to resist stresses over a long span.

b). On the hardening of the cement paste inside the concrete, it presents excellent mechanical properties.

c). On the hardening of the cement paste inside the concrete, it corresponds to the surface features of the steel.

5. a). A category of non-steel reinforcement is concrete with fibrous material that enhances the structural compression strength.

b). A category of non-steel reinforcement is concrete with fibrous material that enhances the structural bending strength.

c). A category of non-steel reinforcement is concrete with fibrous material that enhances the structural tensile strength.
