The study content includes the abrasion resistance performances of the aggregate and the characteristics of powder, and the effects of the coarse aggregate coated by powder on the mechanic performance, anti - permeability and frost - resistance capability of concrete by using the blended aggregate of rcc with different powder content
通過對粗骨料抗磨耗性能、物理性能及裹粉性能進行研究，使用不同裹粉含量的粗骨料拌制碾壓混凝土，分析了粗骨料表面裹粉對碾壓混凝土力學性能、耐久性能的影響。 -
The results show that the compressive strength, splitting tensile strength and flexural strength increase respectively with the addition of steel fibers, but the compressive strength increases little compared with the splitting tensile strength and flexural strength ; for the same kind of steel fiber reinforced concrete, the compressive strength, splitting tensile strength and flexural strength of steel fiber reinforced regenerated concrete are higher than those of steel fiber reinforced pebble concrete ; the load - bearing capacity of blended steel fiber reinforced concrete is less than that of single dimension steel fiber reinforced concrete ; the use of steel fiber reinforced regenerated concrete whose aggregate is made of regenerated concrete can not only turn waste into treasure, but also reduce environmental pollution and realize the recycle of resources, and its load - bearing capacity is far higher than that of steel
結果顯示:由於鋼纖維的加入，混凝土的抗壓強度、劈裂強度和彎曲強度都有不同程度的提高，但抗壓強度不及劈裂強度和彎曲強度提高顯著;對于同種鋼纖維混凝土，鋼纖維再生混凝土的抗壓強度、劈裂強度和彎曲強度比鋼纖維卵石混凝土的相應強度大;混雜尺寸鋼纖維混凝土的承載能力不如單一尺寸鋼纖維混凝土的承載能力;以再生混凝土作為基體的鋼纖維再生混凝土不僅可以「變廢為寶」 ，減少環境污染，實現資源的重復利用，而且其承載能力比鋼纖維卵石混凝土高很多。 3 .總結出鋼纖維混凝土抗拉強度和彎拉強度關系的計算公式。
