The bulk concrete refers to a mass concrete having a minimum size of a concrete structure of not less than 1m, or a concrete expected to cause harmful crack generation due to temperature change and shrinkage caused by hydration of a cementitious material in the concrete. Generally, mass concrete mainly appears in the hydropower engineering, and with the development of bridge engineering, a bridge foundation and an anchorage anchor body also adopt the mass concrete. In the construction process of the large-volume concrete, cracks can be generated due to cement hydration heat, external temperature change, concrete shrinkage and the like. Wherein, the hydration heat refers to the heat released by cement in the hydration process; the crack generation caused by the change of the outside air temperature means that the temperature difference is larger, the temperature stress is larger, the heat dissipation of mass concrete is difficult under the high-temperature condition, the highest temperature in the concrete can reach 60-65 ℃ generally, and the time is longer, and generally, the temperature difference between cooling water and the interior of the concrete should not exceed 25 ℃; the concrete shrinkage is caused by that the cement only absorbs 20% of water seal when hardened, 80% of water is evaporated, and the volume is shrunk due to the evaporation of the water.
For the above reasons, in the construction stage of mass concrete, it is necessary to control the temperature of mass concrete in combination with the external temperature to prevent cracks from being generated.
