钢纤维增强碾压混凝土性能研究

A Study on the Property of Steel Fiber Reinforced Roller Compacted Concrete (RCC)

文章比较了多类纤维增强碾压混凝土（ＲＣＣ）的施工性能，并研究了硬化钢纤维增强ＲＣＣ的轴向拉伸强度、极限拉伸应变、抗拉弹性模量及抗弯强度等若干力学性能，提出若干改善混凝土固有缺陷（脆性、束裂能力低等）的措施。

Based on the comparison of the construction property of a variety kinds of fiber reinforced roller compacted concrete (RCC) and a study on some mechanical properties of har dened steel fiber reinforced RCC including the axial tensile strength, limit tensile strain, tensile elastic modulus, as well as bending strength, etc., some measures are set forth for eliminating the intrinsic defects (brittleness and low crack resistance, etc.) of concrete.
