It's usually 60 years. The stability and durability of concrete is very good, as long as there is no natural disaster or man-made strong damage, the strength of concrete will not be damaged, reduced, and the life can reach 60 years. However, on the premise of safety, the concrete floor will be renovated once every 60 years, after all, climate and man-made disasters may occur. In addition, due to the expansion and destruction of the coagulant itself, if no countermeasures are taken, the life will be greatly shortened

How to treat coagulants

1. Maintenance method

After concrete pouring is completed, it is necessary to carry out moisture maintenance in time. General sprinkling, covering, spraying curing agents are optional curing methods. The specific choice of which does not need to be based on site conditions, environmental temperature and humidity, component characteristics, technical requirements, construction operations to make the final decision.

2. Maintenance time

Different types of concrete curing time will also vary. Generally speaking, the curing time of concrete prepared with ordinary Portland cement or Portland slag cement is at least 7 days. The curing time of coagulants which are finally prepared by adding retarding admixtures or a large amount of mineral admixtures is more than 14 days.

3. Precautions

During the curing of concrete, it is necessary to prevent the abnormal shrinkage, cracks and other damage phenomena of the concrete due to exposure, wind, cold and other conditions. In addition, the starting time of maintenance should be watered before and after the initial setting after concrete pouring
