摘要:弹性模量是衡量混凝土材料性能的重要参数之一,其大小反映了抵抗弹性形变能力的强弱.对钢纤维增强混凝土和掺聚丙烯腈纤维的橡胶砂浆的弹性模量及抗压强度进行试验.试验结果表明,超短钢纤维混凝土的抗压强度和后期弹性模量较短钢纤维混凝土有明显提升,掺有聚丙烯腈纤维的橡胶砂浆的弹性模量降低明显,改善了橡胶砂浆的韧性和变形能力.

关键词: 弹性模量, 橡胶砂浆, 钢纤维, 混凝土, 聚丙烯腈纤维

Abstract: Experimental study was conducted to investigate the modulus of elasticity and compressive strength of the steel fiber reinforced concrete and the polyacrylonitrile fiber reinforced rubber mortar.Results showed that compared with the short steel fiber reinforced concrete,the micro steel fiber reinforced concrete had a higher compressive strength and post modulus of elasticity.The incorporation of polyacrylonitrile fiber into rubber mortar can reduce the modulus of elasticity of the rubber mortar but improve its toughness and deformability.

Key words: modulus of elasticity, rubber mortar, steel fiber, concrete, polyacrylonitrile fiber
