Is concrete a conductor or a insulator?
Concrete is a poor conductor of electricity, so it is considered an insulator. Electricity does not flow easily through concrete due to its high resistance.
Is concrete an insulator or conductor?
Concrete is a poor conductor of electricity, so it can be considered an insulator. However, it may still allow some degree of electrical conduction due to impurities or moisture present in the material.
Why is concrete a conductor of heat?
Everything is a conductor of heat. A molecule gets shaken up by its warmer neighbors, then transfers that shaking to it's cooler neighbors. Concrete's thermal conductivity is about 1 W/m-K, so it's a fairly poor conductor for a solid. For comparison, the lowest conductivity in a compact (i.e. has no holes) solid is about 0.1 W/m-K, steels are around 20, and copper is around 400.
Can electrical current flow through concrete?
Yes, electrical current can flow through concrete as it is a good conductor of electricity. However, the resistance of the concrete will depend on its moisture content and composition. Generally, wet concrete will conduct electricity better than dry concrete.
Why storage heaters contain concrete blocks though the specific heat capacity of concrete's lower than water?
Because water is a fluid so heat can transfer by convection to the surface of the radiator can be 'radiated' into the room very quickly. Concrete is an aerated solid so can't do this, and is a very poor conductor, so loses its heat a lot more slowly. The concrete bricks are also aerated, and air is an even poorer conductor than concrete.

Is concrete a good conductor of heat?
0.75 (kJ/kg K) is the specific heat of concrete
Are Concrete Storm Shelters safe from lightning?
concrete is not a conductor of elec. a well built shelter would be steel reinforced . Much safer than a steel one Dennis Vail 40 years building of building concrete storm cellars and saferooms on site cellarman100@hotmail.com

Is concreate a good or poor conductor?
of heat, not great because it has air pockets. Of sound, pretty good because it is a solid. of electricity, it is an insulator. Be more specific.
Why does concrete floor feel cold when you touch it?
Concrete is a good conductor of heat, which means it can quickly absorb and transfer heat away from your body when you touch it. This rapid transfer of heat can make the concrete feel cold to the touch, even if the actual temperature of the concrete is the same as the surrounding air.
How does electricity pass through concrete?
All concrete contains water (both water of crystallization and unreacted free water) and dissolved salts of various kinds, this electrolyte easily conducts electricity. Reinforced concrete also has a network of prestressed steel bars running throughout it, which are very good conductors.
Is the word conduct a concrete noun?
No, the noun 'conduct' (con duct) is an abstract noun, a word for a manner of behavior or the management of an activity or process; a word for a concept.The concrete noun form of the verb to conduct (con duct) is conductor, a word for a person or a thing.
