                鋼纖維檢測
                Steel Fiber Detection
                1、鋼纖維的抗拉強度檢驗,要求其抗拉強度不低于380MPa;
                1. Testing the tensile strength of steel fibers requires that the tensile strength of steel fibers should not be less than 380 MPa.
                2、鋼纖維的抗彎拆性能,鋼纖維應能經受直徑3㎜鋼棒彎拆90°不斷,每批次檢驗不少于10根;
                2. Bending and disassembly resistance of steel fibers, steel fibers should be able to withstand bending and disassembly of steel rods with diameter of 3_90 degrees continuously, and not less than 10 steel rods should be inspected in each batch.
                3、雜質含量,鋼纖維表面不得有油污,不得鍍有有害物質或影響鋼纖維與混凝土粘接的雜質。
                3. Impurity content, steel fiber surface shall not be oil stain, no harmful substances or impurities affecting the bonding between steel fiber and concrete.
                4、鋼纖維的長度偏差不應超過標準長度的10%,每批次至少隨機抽查10根以上;
                4. The length deviation of steel fibers should not exceed 10% of the standard length. At least 10 fibers should be randomly sampled in each batch.
                5、鋼纖維的直徑或等效直徑合格率不得低于90%,可采取重量法檢驗,每批次抽檢100根,用天平稱量,卡尺測其長度,要求得到的等效平均值滿足規定;
                5. The qualified rate of diameter or equivalent diameter of steel fibers shall not be less than 90%. It can be checked by gravimetric method. 100 pieces of steel fibers can be sampled in each batch. The length of steel fibers can be measured by balance and caliper. The required equivalent average value meets the requirements.
                原材料的檢驗:
                Inspection of raw materials:
                必須滿足上述原材料的質量控制標準,應按照公路工程施工技術規范的要求進行檢驗。
                The quality control standards of the above raw materials must be met and should be inspected in accordance with the requirements of the technical specifications for highway engineering construction.
                鋼纖維混凝土的檢驗:
                Inspection of steel fiber reinforced concrete:
                應重點檢驗鋼纖維混凝土的和易性、塌落度和水灰比等,同時必須現場目檢鋼纖維在混凝土的分布情況,
                The workability, collapse degree and water cement ratio of steel fiber reinforced concrete should be emphatically examined. At the same time, the distribution of steel fiber in concrete must be inspected by visual inspection on site.
                發現有鋼纖維結團現象應延長拌和時間
                The mixing time should be prolonged when the phenomenon of steel fiber agglomeration is found.
