“…Under the same conditions, the higher the clay content in the soil, the stronger the shrinkage ability of the cement-stabilized soil. Sheng [15] applied the grey system theory to establish a grey prediction model depicting the influencing factors of aggregate fractal dimension, strength, and moisture content of a mixture, and Sylovanyuk et al [16] proposed the fracture toughness (K IC ) for predicting the crack resistance of fiber composites based on cement matrix production. e use of steel slag as an aggregate and the use of lime fly ash as a binder to prepare the base material [17] or the addition of steel fiber and rubber or other admixtures [18] can improve the splitting strength and shrinkage of cement-stabilized materials.…”

Using coral sand as an aggregate to build the base layer of pavement on islands and along coasts in China has the potential to not only reduce construction costs and time but also lessen carbon emissions during transportation. Due to coral sand’s fragility, porosity, and high water absorption, the amount of cement is higher than that of ordinary cement-stabilized gravel, which leads to the high strength but easy cracking of the base layer. The expansion agent is added to improve the shrinkage characteristics of cement-stabilized coral sand. To ensure the validity of our results, the mixing ratio of cement-stabilized coral sand was optimized according to its characteristics, and the effects of the cement content, the expansion agent type, and dosage on coral sand’s mechanical properties, dry shrinkage, and antiscour performance of cement-stabilized coral sand were studied using an orthogonal test. The results indicate that cement content is one of the most important factors affecting compressive strength, scouring, and dry shrinkage. The optimal mix ratio of cement-stabilized coral sand is 6% cement to 8% CAS expansion agent (accounting for cement), which is sufficient to meet the design criteria for heavy-duty traffic subbases.
