The specification of concrete curing is: the temperature is between 18℃ and 22℃, and the humidity is not lower than 95%. The purpose of concrete curing is to ensure the normal hardening of concrete pavement and become a cement pavement suitable for walking. Therefore, the concrete must be cured at a suitable temperature and humidity, with the lowest temperature not lower than 18 degrees, the highest temperature not higher than 22 degrees, and the lowest moderate degree not lower than 95%. If not, the concrete will not harden normally, and the concrete cured under such curing conditions is the cement road suitable for walking.
