摘   要:研究了铁尾矿砂、浮石、粉煤灰陶粒对轻骨料混凝土抗压强度、劈裂抗拉强度、弹性模量和干表观密度的影响,并利用Design-Expert软件对配合比进行了优化。结果表明:随着粉煤灰陶粒相对掺量的增加,轻骨料混凝土的力学性能提高,干表观密度增大;随着浮石相对掺量的增加,轻骨料混凝土的力学性能降低,干表观密度减小;随着砂率的增大,轻骨料混凝土的干表观密度增大,且当砂率为40%时,轻骨料混凝土的力学性能达到最佳;Design-Expert软件优化结果表明,当粉煤灰陶粒与浮石的质量比为3.13、砂率为36%时,可制备出力学性能较优且干表观密度较低的轻骨料混凝土。 Abstract: The effects of iron tailing sand, pumice and fly ash ceramsite on the compressive strength, splitting tensile strength, elastic modulus and dry apparent density of lightweight aggregate concrete were studied, and the mix proportion was optimized by using Design-Expert software. The results show that the mechanical properties and dry apparent density of lightweight aggregate concrete increase with the increase of the relative content of fly ash ceramsite. With the increase of pumice relative content, the mechanical properties and dry apparent density of lightweight aggregate concrete decrease. With the increase of sand ratio, the dry apparent density of lightweight aggregate concrete increases, and the mechanical properties of lightweight aggregate concrete reach the best when the sand ratio is 40%. The optimization results of Design-Expert software show that when the mass ratio of fly ash ceramsite to pumice is 3.13 and the sand ratio is 36%, the lightweight aggregate concrete with excellent mechanical properties and low dry apparent density can be prepared.

(1)在m粉煤灰陶粒 /m浮石小于3.0的情况下,随着m粉煤灰陶粒 /m浮石的增大,轻骨料混凝土的力学性能迅速增加;在m粉煤灰陶粒 /m浮石大于3.0的情况下,随着m粉煤灰陶粒 /m浮石的增大,轻骨料混凝土的力学性能增幅缓慢。
  (2)随着砂率的增加,轻骨料混凝土的抗压强度、劈裂抗拉强度和弹性模量均呈先增大后减小的趋势,且当砂率为40%时,力学性能达到最佳。
  (3)Design-Expert软件优化结果表明,当砂率为36%、m粉煤灰陶粒 /m浮石=3.13时,轻骨料混凝土的综合性能较优,实测抗压强度为65.1 MPa、劈裂抗拉强度为3.56 MPa、弹性模量为3.0×104 MPa、干表观密度为1 846 kg/m3
