摘要
该文研究了在室内环境中地聚物基植物纤维复合材料发生泛碱后对静曲强度与内结合强度的影响,与未发生泛碱现象的袋装试样相比,发生泛碱现象的室内试样其强度保留效果更好。采用FTIR、SEM和EDS对泛碱物质的结构及成分进行分析,结果表明,Na是参与泛碱的主要元素,泛碱物质主要是碳酸钠,和少量的碳酸钙。
In this paper,the effect of efflorescence on bending strength and internal bonding strength of geopolymer-based plant fiber composites in indoor environment was studied.Compared with the bagged samples without efflorescence,the indoor samples with efflorescence have better strength retention.The FTIR,SEM and EDS were used to analyze the structure and composition of efflorescence substance.The results showed that Na was the main element involved in the efflorescence phenomenon,and efflorescence substances are mainly sodium carbonate,and a small amount of calcium carbonate.
