摘要：研究了水胶比、碱当量和粉煤灰漂珠掺量对碱矿渣水泥灌浆料流动度和抗压强度的影响。结果表明：随着水胶比的增加，碱矿渣水泥灌浆料的流动度增大；随着碱当量的增加，碱矿渣水泥灌浆料的流动度和抗压强度均呈先增后减的趋势；粉煤灰漂珠能有效改善碱矿渣水泥灌浆料的流动度，且掺入适量的粉煤灰漂珠，对碱矿渣水泥灌浆料的抗压强度影响不大。总体而言，当水胶比为0.4、砂胶比为1.5、水玻璃模数为1.4、碱当量为8%、粉煤灰漂珠掺量为10%时，碱矿渣水泥灌浆料的各项性能较好，满足相关标准要求。 Abstract: The influence of water-binder ratio, alkali equivalent and fly ash microsphere content on the fluidity and compressive strength of alkali-activated slag cement grouting material was studied. The results show that with the increase of water-binder ratio, the fluidity of alkali-activated slag cement grouting material increases. With the increase of alkali equivalent, the fluidity and compressive strength of the alkali-activated slag cement grouting material increase first and then decrease. The fly ash microsphere can improve the fluidity of alkali-activated slag cement grouting material, and the proper content of fly ash microsphere has little effect on the compressive strength of alkali-activated slag cement grouting material. In general, when the water-binder ratio is 0.4, the sand-cement ratio is 1.5, the water glass modulus is 1.4, the alkali equivalent is 8% and the fly ash microsphere content is 10%, the performance of alkali-activated slag cement grouting material is better, and meets the relevant standard requirements.

Abstract: The influence of water-binder ratio, alkali equivalent and fly ash microsphere content on the fluidity and compressive strength of alkali-activated slag cement grouting material was studied. The results show that with the increase of water-binder ratio, the fluidity of alkali-activated slag cement grouting material increases. With the increase of alkali equivalent, the fluidity and compressive strength of the alkali-activated slag cement grouting material increase first and then decrease. The fly ash microsphere can improve the fluidity of alkali-activated slag cement grouting material, and the proper content of fly ash microsphere has little effect on the compressive strength of alkali-activated slag cement grouting material. In general, when the water-binder ratio is 0.4, the sand-cement ratio is 1.5, the water glass modulus is 1.4, the alkali equivalent is 8% and the fly ash microsphere content is 10%, the performance of alkali-activated slag cement grouting material is better, and meets the relevant standard requirements.
