200-meter-level high-fall long-slope-distance panel concrete and warehousing method
The invention relates to 200-meter-level high-fall long-slope-distance panel concrete and a warehousing method, and the slump of the concrete is larger than or equal to 30 mm and smaller than or equal to 70 mm. The concrete comprises 117-126 kg/m < 3 > of water, 195-224 kg/m < 3 > of cement, 52-70 kg/m < 3 > of I-grade fly ash, 759-777 kg/m < 3 > of artificial sand, 628-643 kg/m < 3 > of small stone, 628-643 kg/m < 3 > of medium stone, 0.9 kg/m < 3 > of polyvinyl alcohol fiber and 1.62-1.76 kg/m < 3 > of a water reducing agent, wherein the mixing amount of an air entraining agent is 3.5%-4.5% of the air content of the concrete. The water cement ratio is effectively reduced, the hydration heat is reduced, the concrete strength is improved, and the possibility of concrete surface cracks is effectively reduced. By the adoption of the high-fall large-inclined-length concrete panel pouring warehousing method, the construction efficiency can be effectively improved, and the construction cost is reduced.
本发明涉及一种200米级高落差长斜距面板混凝土及入仓方法，该混凝土的塌落度为，大于等于30mm，小于等于70mm。所述混凝土的配合比为水117～126kg/m3，水泥195～224kg/m3，Ⅰ级粉煤灰52～70kg/m3，人工砂759～777kg/m3，小石628～643kg/m3，中石628～643kg/m3，聚乙烯醇纤维0.9kg/m3，减水剂1.62～1.76kg/m3，引气剂掺量为混凝土含气量的3.5％～4.5％。采用本发明有效降低水灰比，减小水化热，提高了混凝土强度，有效减小混凝土表面裂缝的可能。采用本发明一种高落差大斜长混凝土面板浇筑入仓方法可有效提高施工效率，降低施工费用。
