ABSTRACT

The rapid construction of roller compacted concrete (RCC) faces prominent challenges, including concentrated release of hydration heat caused by continuous thin-layer rolling in large warehouse surfaces, deteriorated heat dissipation conditions, and poor coordination between temperature control measures and construction rhythms. This paper systematically analyzes the characteristics of rapid construction technology and its constraint mechanism on temperature control and anti-cracking performance. On this basis, a mix proportion optimization design is carried out. By selecting low hydration heat cementitious materials, optimizing aggregate gradation and paste-aggregate ratio, and coordinating setting time and early strength development, the adiabatic temperature rise of concrete is reduced by more than 20%. Furthermore, collaborative regulation measures are proposed, including multi-period inhibition of pouring temperature and matching of heat preservation curing with rolling construction rhythm. A closed-loop evaluation system based on the feedback of temperature-stress field simulation is also established. The research findings realize the in-depth coupling of mix proportion design, temperature control and anti-cracking measures with rapid construction technology, providing a systematic technical solution for the rapid construction of RCC. Taking the Kekka Hydropower Station in Angola as the engineering example, under the tropical climate condition with an annual average temperature exceeding 25°C, a temperature control system combining secondary air cooling, ice addition and cold water pre-cooling technology with multiple curing methods is adopted based on simulation results. The continuous and rapid construction of large-warehouse and large-lift RCC is successfully realized, which verifies the engineering applicability of the technical framework proposed in this paper.
