摘要
通过对3 d、7 d、14 d、28 d、60 d、90 d龄期下5种偏高岭土掺入比的水泥土强度研究,得到了用粉质粘土制得的水泥土当中强度达到最佳时的偏高岭土掺入比,并结合水泥土和偏高岭土的作用机理,解释了掺入偏高岭土后的水泥土强度随偏高岭土掺入比变化的原因。此外,通过软件Origin 8.6对不同偏高岭土掺入比下水泥土强度随龄期的变化规律进行了统计分析,得到了在同一偏高岭土掺入比下水泥土无侧限抗压强度与龄期的统计公式。
In order to obtain best metakaolin ratio in silty clay of cemented soil by 3 d,7 d, 14 d,28 d,60 d and 90 d ages with five contents of metakaolin, a series of unconfined compressive strengths are conducted on the cemented soil samples. Combined with cemented soil and metakaolin mechanism, the reasons for the strength of cemented soil after incorporation of metakaolin with metakaolin ratio changing are explained. In addition, the relationship of unconfined compressive strength and age of cemented soil with the same metalkaolin ratio is statistically analyzed by using Origin 8. 6 software. The statistical formula is set up to predict the compressive strength of cemented soil by ages under the same metakaolin ratio.
