摘要
采用粉煤灰陶粒配制了强度61MPa、密度1 857kg/m3的高强轻骨料混凝土。并通过试验研究了高性能异型塑钢纤维(HPP)对轻骨料混凝土抗压强度、抗劈拉强度以及表观密度的影响,研究表明,不同掺量的HPP纤维对轻骨料混凝土的表观密度、抗压强度没有显著影响,但能明显改善轻骨料混凝土的抗拉性能。
Flyash-haydite was used to mix up high strength light-aggregate concrete with strength of 61MPa and density of(1 857kg/)m^3.The influence of HPP fiber on the compression strength,tensile strength and apparent density of light-aggregate concrete was also studied.The research indicates that HPP fiber can increase the tensile strength of light-aggregate concrete greatly.However there's no much influence on the compressive strength and apparent density of light-aggregate concrete.
