Benefits of technology

This technology helps prevent damage caused by excessive temperatures inside cement during its production process or use for longer periods without losing strength due to overheated conditions. It also improves coolability with less liquid being used compared to traditional methods like spray-on coatings on surfaces.

Problems solved by technology

This technical problem addressed in this patents relates to improving the design of casted concrete structures during their manufacturing processes due to factors like thermal stress cracking (TCC) which can occur when there has been significant changes made over time from environmental conditions affecting both interior temperatures and external environments. These issues lead to structural defects called cracks formed through these stresses.

Abstract

The invention discloses a mass concrete pouring cooling construction method for an amusement project. The mass concrete pouring cooling construction method is characterized in that a circulating cooling condensation pipe is arranged in concrete, and circulating water is introduced to reduce the internal temperature of the concrete, so that hydration heat generated in the concrete can be quickly and effectively reduced, and the internal and external temperature difference of the concrete is reduced; and the circulating water is adopted for reducing the internal temperature of the concrete, materials are easy to obtain, materials are convenient to use, the cooling effect is good, the cooling speed of the concrete is conveniently controlled by controlling the flow speed of the circulating water, concrete cracks can be reduced to the maximum extent, and the construction quality of mass concrete is guaranteed.
