摘　　要：以内蒙古地区天然浮石为粗骨料,通过对不同掺量玻璃纤维轻骨料混凝土力学性能的试验,研究了玻璃纤维轻骨料混凝土的抗压强度、抗折强度及劈裂抗拉强度,并得出玻璃纤维掺量为0.5 kg/m3时,轻骨料混凝土的抗压强度、抗折强度和劈裂抗拉强度比其它几种掺量下强度要高;从微观角度研究了轻骨料混凝土破坏后纤维表面及纤维与浆体界面粘结情况。By using the natural pumice stone in Inner Mongolia as coarse aggregate,the compressive strength,flexural strength and splitting tensile strength of glass fiber lightweight aggregate concrete were studied though testing the mechanical properties of concrete with different dosage of glass fiber. It is obtained that when the glass fiber dosage is 0.5 kg/m^3, compressive strength,flex- ural strength and splitting tensile strength of glass fiber lightweight aggregate concrete are higher than those with other dosages. Fiber surface and fiber slurry interface bonding situation after destruction of lightweight aggregate concrete were studied from the microscopic point of view.
