Maintenance regulation and control method for large-volume steam-curing-free ultra-high-performance concrete
The invention relates to a large-volume steam-curing-free ultra-high performance concrete curing regulation and control method, which comprises the following steps of: erecting a supporting template at the bottom and the periphery of the poured ultra-high performance concrete, installing an aluminum foil heat-insulating plate at the periphery of the supporting template, and reserving a gap of 5-10cm between the aluminum foil heat-insulating plate and the supporting template, an inorganic heat preservation material is poured into a gap between the aluminum foil heat preservation plate and the supporting formwork, the ultra-high performance concrete is cured through the inorganic heat preservation material, the ultra-high performance concrete is cured through the inorganic heat preservation material, and hot curing is conducted through the inorganic heat preservation material and the aluminum foil heat preservation plate. The cooling rate of the ultra-high performance concrete is smaller than or equal to 1.5 DEG C/d, and the technical problems that a traditional curing mode is poor in heat insulation effect and too high in cooling rate are solved.
本发明涉及一种大体积免蒸养超高性能混凝土养护调控方法，该方法包括在超高性能混凝土浇筑的底部和周围架设支撑模板，在所述支撑模板四周安装铝箔保温板，所述的铝箔保温板与支撑模板之间预留5‑10cm的间隙，在所述铝箔保温板与支撑模板之间的间隙浇筑无机保温材料，通过所述无机保温材料对所述超高性能混凝土进行养护，通过无机保温材料对所述超高性能混凝土进行养护，通过无机保温材料与铝箔保温板进行热养护，使得超高性能混凝土的降温速率≤1.5℃/d，解决了传统养护方式隔热效果较差、降温速率过快的技术问题。
