碩士 === 國立中興大學 === 土木工程學系所 === 94 === The objective of this thesis is to establish the relation between the exposed length obtained from penetration tests and the compressive strength of RMSM (Ready-Mixed Soil Material) which is produced by mixing Portland cement with soil in the field. The compressive strength of RMSM ranges from 10 to 50 kgf/cm2. The influence of the addition of slag on the exposed length-strength relationship is also discussed. A powder actuated gun with white cartridge was used as a penetration tool in the study. The experimental results show that the selected powder actuated gun is suitable for the penetration tests with a gun head 2.5 cm away from the test surface. A good relationship between the exposed length and the compressive strength was obtained for RMSM with strength ranging between 7 ~ 84 kgf/cm2. The results also show that the variation in mixture proportions of RMSM does not have a significant effect on the exposed length and strength relationship.
