Abstract

The preparation and characterization of composite materials based on geopolymers obtained from fly ash and epoxy resins are reported for the first time. These materials have been prepared through a synthetic method based on the concurrent reticulation of the organic and inorganic components that allows the formation of hydrogen bonding between the phases, ensuring a very high compatibility between them. These new composites show significantly improved mechanical properties if compared to neat geopolymers with the same composition and comparable performances in respect to analogous geopolymer-based composites obtained starting from more expensive raw material such as metakaolin. The positive combination of an easy synthetic approach with the use of industrial by-products has allowed producing novel low cost aluminosilicate binders that, thanks to their thixotropicity and good adhesion against materials commonly used in building constructions, could be used within the field of sustainable building.

摘要

首次报道了基于粉煤灰和环氧树脂制备的地质聚合物复合材料的制备及表征。这些材料通过一种基于有机和无机组分同时交联的合成方法制备，该方法能使各相之间形成氢键，确保它们之间具有非常高的相容性。与具有相同组成的纯地质聚合物相比，这些新型复合材料的机械性能显著提高，并且与从偏高岭土等更昂贵原料制得的类似地质聚合物基复合材料相比，性能相当。简便的合成方法与工业副产品的使用相结合，使得能够生产新型低成本硅铝酸盐粘结剂，由于其触变性以及对建筑施工中常用材料的良好粘附性，这些粘结剂可用于可持续建筑领域。
