Abstract

<p>This study explores the fluidity and strength characteristics of cement stabilized soil utilizing three different sand content ratios. The research scrutinizes the relationship between the water content ratio, flow value, and 28-day unconfined compression strength (qu28), while maintaining a constant water cement ratio. It was determined thatqu28 of the cement stabilized soil is influenced by both the water cement ratio and the mass of soil particles, given that the original soil remains constant. Additionally, an examination of the mix proportions of cement stabilized soil with a field strength of 500 kN/m2 was conducted under four conditions of flow values: 90, 120, 150, and 210 mm. A comparison between the mix proportion of 100% clay and a 50% sand mixture in cement stabilized soil revealed that the latter reduced the cement mass by 33 to 42 kg/m3 (a ratio of 22 to 20%).</p>
