响应面分析外加固化材料对滩涂淤泥早期强度的影响
|
摘要
通过响应面法研究粉煤灰、胶凝材料、氧化镁、TEA、固化剂FJ、固化剂KG对滩涂淤泥固化早期强度的影响。结果表明,粉煤灰和胶凝材料的交互作用对滩涂淤泥固化早期强度有显著影响。最优配方为:水泥基材料占淤泥干重19%,粉煤灰占淤泥干重20%,胶凝材料占水泥基材料22.4%,固化剂KG占水泥基材料30%。
The influence of fly ash,cementitious material,magnesia,TEA,solidification material FJ and hardener KG on the early strength of beach sediment was studied with response surface analysis. The results show that the interaction between fly ash and cementitious material has a significant effect on the early strength of beach sediment. The optimal formula is following: the cement-based material accounts for19% of the dry weight of sediment,the fly ash accounts for 20% of the dry weight of sediment,cementitious material accounts for 22. 4% of cementitious materials,and solidification material KG accounts for30% of cementitious materials.
