摘要：基于矿渣基早强无机聚合物，分别采用2种粉煤灰制备粉煤灰/矿渣无机聚合物（FSIP），对其工作性能、早期力学性能和物相组成进行分析，并进一步研究了粉煤灰掺量为0、5%和15%的无机聚合物基快硬混凝土（IPFC）的早期力学性能变化规律。结果表明，粉煤灰的掺入对FSIP的工作性能有显著的提升效果，但整体上会对FSIP和IPFC的力学性能造成一定的削弱；粉煤灰能使材料的内部结构更加密实，但对其XRD图谱并没有明显的改变，且粉煤灰掺量越大，材料的非晶体含量越高。

Abstract：Based on slag-based early strength inorganic polymer，fly ash-slag inorganic polymer（FSIP） with two kinds of fly ash were prepared，the working performance，early mechanical properties and phase composition were analyzed，and the early mechanical properties of inorganic polymer based fast-hardening concrete（IPFC） with fly ash content of 0，5% and 15% were further studied. The results show that the addition of fly ash can improve the performance of slag-based early strength inorganic polymer remarkably，but on the whole，the mechanical properties of FSIP and IPFC will be weakened to some extent，the internal structure of the material will become dense，while the XRD spectrum of the material does not change obviously after adding fly ash，and the higher the fly ash content，the higher the amorphous content of the material is.
