Effect of Cooling by Water Flowing in Nonmetal Pipes Embedded in Mass Concrete

Although roller compacted concrete was developed in recent years, artificial pipe cooling still is used widely to control the temperature of mass concrete in dam construction. There is a tendency to replace the metal pipes with nonmetal pipes, but there is not an appropriate method to compute the ef...

Summary:Although roller compacted concrete was developed in recent years, artificial pipe cooling still is used widely to control the temperature of mass concrete in dam construction. There is a tendency to replace the metal pipes with nonmetal pipes, but there is not an appropriate method to compute the effect of cooling by nonmetal pipes. This problem is studied in this paper. Four methods are given to compute the effect of cooling, one formula is given to compute the radius of pipe, one formula is given to compute the horizontal spacing between pipes, and one formula is given to compute the time required for two different kinds of pipes to get the same cooling effect. All these methods and formulas are very convenient to use. The radius, the spacing, the time required to get a predetermined temperature in mass concrete and the economy of the artificial cooling by nonmetal pipes relative to the metal pipes may be determined by these formulas.
