A higher steel slag dosage will increase the condensation of geopolymers (You et al., 2019). The reason is that the main phase of steel slag is amorphous, which increases the density of geopolymer samples due to higher reaction activity and lower total porosity (Sun et al., 2020). Furthermore, compressive strength increases with raising …

Use of steel slag as railway ballast: A review. ... (SSB) can potentially reduce the track maintenance costs owing to lower settlement and breakage, enhance the lateral resistance owing to its higher density, and provide better riding comfort because of higher resilient modulus. Moreover, the use of steel slag as railway ballast is anticipated ...
The need to reuse waste materials is a fundamental aspect in sustainable development. Two types of materials, crushed rubber (CR) and steel slag (SS), were selected to analyze their effects on micro-paving asphalt mixtures. The methodology was carried out in two phases: first, the behavior of these materials in cold asphalt mixtures …
