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.

Is concrete a conductor?
Concrete is a poor conductor of electricity, as it is not a metal and does not contain free-moving electrons that can carry electric charge effectively. However, it can conduct heat due to its density and composition.
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.
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.
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 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.

Is concrete a good conductor of heat?
0.75 (kJ/kg K) is the specific heat of concrete

Why a diamond is a carbon but not heat conductor?
because it is a heat conductor!
Is duct tape a good conductor of heat?
Duct tape is not a good conductor of heat. Its composition and thickness make it a poor conductor, so it does not readily transfer heat.
Why is aluminum the worst heat conductor?
Aluminium is a good conductor of heat.
Is wood a poor heat conductor?
Wood is a poor conductor of heat.
Is a pencil a good conductor of heat?
No, a pencil is not a good conductor of heat because it is made of graphite, which is a poor conductor of heat. Heat will not travel easily through a pencil, making it a good insulator rather than a conductor of heat.
