Firstly, the experimental value of the soil PH test to gain a better understanding of soil and examine if the pH is greater than 5.3. According to ACI study, if cement solidified soil PH value exceeds 5.3, it will help to enhance the cement hydration, then investigate the relationship between compressive strength with different curing periods of 3 days, 7 days, 14 days, 28 days separately. Additionally, it is required to examine inter-relationship of the pH value, best water maximum and dry density of soil versus HSC301 and soil versus cement modifier The results showed that soil at the different coefficient of uniformity (CU) mixes with the Ground Improvement Admixture at the different proportion mixtures and type I cement, its compressive strength increases with the ages; and also increases along with the geological of modifier and type I cement increases. The compressive strength of the soil- Ground Improvement Admixture mixture is higher than that of the soil-cement mixture. PH value of the soil mixture increases along with the Ground Improvement Admixture and Type I cement increases; and the compressive strength of soil mixture also increases with the PH value. Moreover, the optimum moisture content for the soil - geology modifier mixture and for the soil - cement mixture increases with reducing of the Ground Improvement Admixture and Type I cement, otherwise the maximum dry density had reverse results.
