摘要
通过试验探讨了粉煤灰掺量对再生混凝土抗压强度的影响,试验表明,随着粉煤灰掺量的增加,再生混凝土的抗压强度先增大后减小,粉煤灰掺量约为10%的再生混凝土抗压强度达到最大。结合蒙特卡罗方法和富勒级配理论,应用Ansys的APDL参数化编程,选取合适的材料参数和新老砂浆界面强度模拟再生混凝土试件加载过程,模拟结果和试验现象较为吻合。
The paper studies the influence of fly ash＇s dosage on compressive strength of recycled concrete. Results show that recycled concrete＇s compressive strength firstly increases then decreases with the increasing dosage of fly ash. The compressive strength of recycled concrete reaches maximum when dosage of fly ash is 10%. Combined with Monte Carlo method and Fuller distribution theory, the paper uses APDL parametric programming of Ansys to simulate the single axis compressive test of recycled concrete specimens through selecting suitable material parameters and interface strength of new and old mortar. The simulation results fit with the experimental phenomenon.
