Damage or collapse in extreme earthquakes is an example of a serviceability limit state.

Traditionally, _______basic types of Portland cement have been produced.

The two general ingredients in concrete are _______. Select two.

Prolonged moist curing leads to lower concrete strength.

Grade 40, 60, and 75 reinforcement have minimum ultimate tensile strengths of 40 ksi, 60 ksi, and 75 ksi, respectively.

Which two tests are generally used to test the tensile strength of concrete?

Given that dead load = 40 psf, live load = 75 psf, roof live load = 30 psf, snow load = 50 psf, and wind load = 15 psf, determine the largest factored load.

Given that dead load = 20 psf, live load = 95 psf, roof live load = 20 psf, snow load = 50 psf, and wind load = 30 psf, determine the largest factored load.

At very slow loading rates, the strength of concrete increases.

Plain (non-reinforced) concrete has an assumed unit weight of _______.
