地质聚合物是 Davidovits 设计的一种无机聚合物。在建筑材料领域，已经研究了由金属离子（例如Si4+和Al3+）与碱性溶液（例如氢氧化钠溶液和硅酸钠溶液）之间的聚合物反应产生的硬化体。地质聚合物具有多种优越特性，例如高强度和高耐硫酸性。因此，地质聚合物可以应用于预制混凝土产品，例如污水管道。制造地质聚合物时需要考虑多种设计参数，这使得很难为这种材料建立合理的设计。本研究提出了使用田口方法的动态方法对粉煤灰基地质聚合物进行优化。采用活性填料和碱性溶液的体积比作为输入值。粉煤灰和磨细的高炉矿渣用作活性填料。考虑了六个设计参数。粉煤灰的类型和进行实验的机构被视为噪声条件。结果证实了该方法在粉煤灰基地质聚合物优化中的适用性。优化后的地质聚合物砂浆还具有稳定的长期抗压强度和优异的耐硫酸性能。
A geopolymer is an inorganic polymer devised by Davidovits. In the field of construction materials, hardened bodies resulting from polymer reactions among metallic ions, such as Si4+and Al3+, and alkaline solutions, such as sodium hydroxide solution and sodium silicate solution, have been studied. Geopolymers have several superior characteristics, such as high strength and high resistance to sulfuric acid. Thus, geopolymers can be applied to precast concrete products, such as sewage pipes. There are several kinds of design parameters to be considered when manufacturing geopolymers, which makes it difficult to establish a reasonable design for this material. The present study presents an optimization of fly ash-based geopolymers using a dynamic approach of the Taguchi method. As an input value, the volume ratio of the active filler and the alkaline solution is adopted. Coal fly ash and ground-granulated blast-furnace slag are used as active fillers. Six design parameters are taken into account. Type of fly ash and the institutes where the experiments were conducted are considered as noise conditions. As a result, the applicability of this method to the optimization of fly ash-based geopolymer is confirmed. The optimized geopolymer mortar was also found to have a stable long-term compressive strength and a superior resistance to sulfuric acid.
