| 1.现将钢纤维及粗骨料投入拌和机拌30秒，使钢纤维分散在石子中，不致结团. 1. Steel fibers and coarse aggregates are now put into the mixer for 30 seconds to disperse the steel fibers in the stones without agglomeration. 2.再将砂及水泥投入拌和机干搅拌30秒. 2. Put the sand and cement into the mixer and stir dry for 30 seconds. 3.再在转动着搅拌机中加水，并再搅拌3分钟左右. 3. Add water to the rotating mixer and stir for about 3 minutes. 压实： 钢纤维混凝土浇注时，随拌随用，连续浇捣，不到分格缝不得甩施工缝，浇捣时应振密实. Compaction: When steel fiber concrete is poured, it should be poured continuously with mixing and use. Construction joints should not be flipped unless the lattice joints are separated. Vibration and compaction should be adopted when pouring and pouring. 抹面压纹： 钢纤维混凝土具有集粗料细，砂率大，纤维乱向分布的特点。采用机械抹平，阻止纤维外露.采用压纹器工艺还应以避免拉毛产生纤维外露现象.经24小时后，应按常规及时养护，夏天应用草包之类覆盖，寒天应注意保温. Surface embossing: Steel fiber reinforced concrete has the characteristics of fine aggregate, high sand ratio and random distribution of fibers. Mechanical smoothing is used to prevent fibre exposure. Embossing process should also be used to avoid fibre exposure. After 24 hours, it should be maintained in time according to routine, covered with straw bales in summer and heat preservation in cold days. |
