The invention belongs to the technical field of concrete premixes, and particularly relates to a steam curing-free ultra-high performance concrete premix for municipal bridges, which is prepared from the following raw materials: 60 to 70 parts of cement, 16 to 26 parts of mineral admixture, 10 to 16 parts of coarse aggregate, 20 to 30 parts of fine aggregate and 8 to 10 parts of aqueous alkali. 12-17 parts of an organic permeable component; 5-9 parts of a hydration catalyst component; the organic bentonite is added into the emulsified asphalt, the organic permeable component, the hydration catalyst component and the inorganic permeable component are added into the base material, and the organic permeable component and the inorganic permeable component are interwoven with each other, so that two component crystals have certain flexibility and are quick and more in crystallization, and the compactness of the concrete is further improved; according to the present invention, the hydration catalyst component is ethylene diamine tetraacetic acid, such that the hydration catalyst component can achieve the good strength under the steam curing-free construction condition so as to provide the good permeation environment for the organic permeation component and the inorganic permeation component, and the hydration accelerating effect on the calcium ion complexation is achieved.
本发明属于混凝土预混料技术领域，具体涉及一种市政桥梁用免蒸汽养护的超高性能混凝土预混料，其原材料组成包括：水泥60‑70份、矿物掺和料16‑26份、粗骨料10‑16份、细骨料20‑30份、碱水剂8‑10份；有机渗透组分12‑17份；水化催化剂组分5‑9份；无机渗透组分10‑16份，向乳化沥青中添加有机膨润土，通过在基料中加入有机渗透组分、水化催化剂组分和无机渗透组分，有机渗透组分和无机渗透组分相互交织，使得两组分结晶物具有一定的柔韧性，结晶快且多，进一步提高混凝土密实性，使得混凝土预混料可以在免蒸汽养护的施工条件下达到良好的强度，水化催化剂组分为乙二胺四乙酸，通过对钙离子络合起到加速水化的作用，为有机渗透组分和无机渗透组分提供良好的渗透环境。
