    Abstract. In the construction of large-scale hydraulic engineering facilities, such as dams, dikes, bridge pylons and other structures, determining the required initial temperature of concrete mixtures in the climatic conditions of Vietnam is important. Lowering the initial temperature of the concrete mixture when mixing it in the composition of water with ice will help reduce the risk of thermal cracks in hardening concrete and reinforced concrete structures. Using the energy balance method, a new formula is proposed for determining the amount of ice required to obtain the required initial temperature of the concrete mix. This formula can be used as a calculation formula in the preparation of concrete mixtures with a given initial temperature. The experimental dependency between the initial temperature of the concrete mixture and the radio between the amount of added ice and the mixing water in the concrete mixture has been established. The type of dependence is linear. The study has real prospects for practical application in terms of including the proposed calculation formula in the updated version of the Vietnamese building standard for concrete and reinforced concrete structures, taking into account the hot and humid climate.
