Cement soil and cement-soil pile are widely used in engineering practice, especially in soft soil foundation treatment, foundation pit maintenance, slope reinforcement, grouting and water blocking works, it has played a very important role. Due to the wide range of cement soil application, cement admixture is also widely used in cement soil, in order to adapt to the actual project in the early strength, enhance, the impermeability and other needs. However, due to regional differences in soil quality, adulterated cement soil engineering properties are also very different, often in engineering practice, they are will be difficult to pile, the strength is not enough and other issues appear, making the treatment costs grow greatly. In this paper, the unconfined compressive strength tests of cement soil with different cement contents, different original water and different curing ages were carried out. The main factors influencing the strength of common cement soil were found by the experiment. The results show that, with the increase of cement content, the strength of cement soil increases linearly. With the increase of soil original water content, the strength of cement soil first increases and then decreases, presenting a parabolic change. With the increase of curing age, the strength of cement soil increases, which shows a good linear relationship between the two, so that the constitutive model of the soil under uniaxial compression is obtained
