Refractory period (physiology)Wikipedia

The refractory period in cardiac physiology is related to the ion currents that in cardiac cells as in nerve cells flow into and out of the cell freely. The flow of ions translates into a change in the voltage of the inside of the cell relative to the extracellular space. As in nerve cells this characteristic change in voltage is referred to as an action potential.

Refractory cement is used for building brick or stone fireplaces barbecues or other installations which are subjected to intense heat. While refractory cement is similar to standard cement in how it is mixed it differs significantly from standard cement in the use of one ingredient.

Proper Refractory MixingInsulation Outlook Magazine

Use a watch or timer when mixing refractory because over-mixing or under-mixing also robs the refractory material of its strength. Mixing refractory properly means using the exact amount of water–not guessing or approximating. Proper mixing means mixing for the correct amount of time providing the refractory to the point of installation in
