Influence of Porosity and Cement Index on the Strength of Cement-Stabilized Soil

The article is divided into four chapters: Introduction, Materials and Methods, Results, and Conclusions. It explores the potential for determining unconfined compressive strength (RC) using porosity and the cementation index (n/Ci) as an alternative to the water-to-cement ratio (w/c) in surface stabilized soils. The study investigates three stabilized soil mixtures with cement contents of 3%, 5%, and 7%, each tested at moisture levels ranging from 6% to 11%. A comparison between the n/Ci and w/c indicators is presented, along with the calibration process for the n/Ci indicator. Furthermore, a detailed methodology for determining the n/Ci indicator is provided. The article also examines correlations between RC and the secant modulus of elasticity (E50). The findings contribute to the development of efficient methods for assessing the mechanical properties of surface-stabilized soils and demonstrate the practical application of the n/Ci indicator.
