Can anybody share how temperature affects strength of concrete?

At high-temperature, concrete loses its strength because of dehydration. On dehydration, it loses all its bond formed by hydration process and starts loosing its strength.

High temperature causes excitation due to which the inter molecular bond are damaged.

High temperature reduce its strength but not affects on it's ultimate strength.

Temperature increase rate of hydration increase. This increase the early setting of cement due to this, pores remained in concrete. And due to this strength decrease.

At 1000° temperature strength reduced to 20%.

Perhaps at high the rate of evaporation is high, water evaporates due to which hydration complete proper hydration cannot take place leading to low strength.

Is it mentioned here, that dehydration is occurring. And In labs, a high temperature of water increases strength.
