Coefficient of thermal expansion of concrete is ________ coefficient of thermal expansion in aggregates.

Correct Answer: Directly proportional
Coefficient of thermal expansion of concrete increases with the increase in coefficient of thermal expansion of aggregates and vice-versa.

What is the relation between the Coefficient of thermal expansion of concrete and the coefficient of thermal expansion in aggregates?

Coefficient of thermal expansion of concrete is __________ coefficient of thermal expansion in aggregates.

Solid concrete blocks are obtained from lightweight aggregates while hollow concrete blocks are obtained from heavy aggregates.

The coefficient of thermal expansion of concrete is similar to that of steel, eliminating large internal stresses due to differences in thermal expansion or contraction.

The coefficient of thermal expansion of concrete is very small to that of steel, eliminating large internal stresses due to differences in thermal expansion or contraction.

If the coefficient of thermal expansion of coarse aggregates and cement paste differs too much, then what happen?

For majority of aggregates, the coefficient of thermal expansion lies between approximately ____________

A concrete column used in bridge construction is cylindrical in shape with a diameter of 1 meter. The column is completely poured in a short interval of time and the hydration of concrete results in the equivalent of a uniform source strength of 0.7 W/kg. Determine the temperature at the center of the cylinder at a time when the outside surface temperature is 75 degree Celsius. The column is sufficiently long so that temperature variation along its length may be neglected. For concrete Average thermal conductivity = 0.95 W/m K Average density = 2300 kg/m3

Generally rounded aggregates are the example of natural aggregates.

Generally angular aggregates are the example of natural aggregates.
