The first is to build a steam curing pond.The general steam curing pond needs 2.5 meters wide, 4 meters long and 3 meters deep.It can also be based on its own production volume and the size of the mold.It also requires the boiler to transport steam to the steam curing pond. The degree of tightness of the steam curing pond is better. After the steam curing pond is completed, it can be used. After the cement pipe is completed, it can be hoisted into the steam curing pond. Well, the higher the temperature, the shorter the time of steaming, the time of steaming is inversely proportional to the temperature of the steam. The higher the temperature, the better.
Natural maintenance means that there is no need for a steam curing pond.After the cement pipe is played, the cement pipe and mold are placed in the open air for natural maintenance.Generally, after the cement pipe is played, it needs to be maintained in the open air for one day, and the mold can be opened the next day. Natural maintenance is also required for 4-6 days, and a special person sprays water three times a day on the cement pipe . The time is usually once in the morning, once at noon, and once in the afternoon. The purpose of the water spray is to maintain the humidity of the cement pipe so that the concrete can slow itself down. Slow condensation, the number of water sprays can also increase and decrease the number of water sprays according to the weather conditions and the humidity of the weather. However, there are more molds for natural maintenance.
