Optimized construction method for industrial factory building steel fiber reinforced concrete terrace
The invention discloses an optimized construction method of an industrial plant steel fiber concrete terrace, which adopts steel fiber concrete for construction, and comprises cement and ordinary Portland cement with the strength grade of 42.5, 475 +/-25 parts; 1245 +/-100 parts of coarse aggregate, namely 5-25mm continuous graded broken stone which is free of alkali activity; the fine aggregate is medium sand, the firmness index is smaller than or equal to 8%, the chloride ion content is smaller than or equal to 0.6%, and the fine aggregate is free of alkali activity and has 510 +/-50 parts; an additive; the length of the steel fiber is 60mm; the diameter of the steel fiber is 0.60 mm, and the mixing amount is 15 kg/m; and 180 +/-10 parts of water. The materials are mixed and stirred to prepare the steel fiber reinforced concrete, the slump is controlled to be 180-200 mm, and the proportion of the raw materials is controlled, so that large-area steel fiber reinforced concrete terrace construction is achieved, and the effect of releasing the internal stress of the steel fiber reinforced concrete terrace is achieved. And cracking, dusting and possible differential settlement of the steel fiber reinforced concrete terrace are prevented, and the construction quality is improved. And the construction cost is saved, and the environmental protection and resource reutilization are promoted.
本发明公开了一种工业厂房钢纤维混凝土地坪的优化施工方法，采用钢纤维混凝土进行施工，包括：水泥，普通硅酸盐水泥,强度等级42.5，475±25份；粗骨料，5‑25mm连续级配碎石，无碱活性，1245±100份；细骨料，为中砂，坚固性指标≤8%，氯离子含量≤0.6%，无碱活性，510±50份；外加剂；钢纤维，钢纤维长度60mm；钢纤维直径0.60mm，掺和量为15kg/m³；水，180±10份。将上述的材料混合搅拌后制备出钢纤维混凝土，塌落度控制在180‑200mm通过原材料配比的控制，实现大面积钢纤维混凝土地坪施工且达到释放钢纤维混凝土地坪内应力的作用，防止钢纤维混凝土地坪开裂、起砂以及可能发生的不均匀沉降的目的，提高施工质量。并且起到节约建设成本，促进环境保护和资源再利用的重大意义。
