Shrinkage is the decrease in the volume of concrete during hardening and drying under constant temperature.

The term “concrete strength” refers to the uniaxial _______ strength.

High strength concrete usually has a lower paste content.

There are no standards governing the quality of water for use in mixing concrete. In most cases, drinking water is not suitable.

The concrete in the core of a spiral column is subjected to a uniform confining stress σ3 of 220 psi. What will the compressive strength σ1 be? The unconfined uniaxial compressive strength is 3,600 psi.

Autogenous shrinkage occurs when moisture diffuses out of the concrete and the exterior shrinks more rapidly than the interior.

Choose the equation that will give the largest factored load when D = 28 kip, L = 2 kip, Lr = 13 kip, and S = 20 kip.

Carbonation shrinkage occurs when moisture diffuses out of the concrete and the exterior shrinks more rapidly than the interior.

Drop panels, capitals, and brackets provide extra depth for moment and shear resistance adjacent to columns.

Shrinkage is the _______ in the volume of concrete during constant temperature.
