THE FEASIBILITY OF CEMENT-CURING AGENT STABILIZED MATERIALS FOR INDUSTRIAL CONSTRUCTION SOLID WASTES IN TERMS OF MECHANICAL PROPERTIES AND MICROSTRUCTURE

ABSTRACT This article discusses the utilization of industrial construction waste for resource recycling and disposal. It focuses on researching a new water-resistant, self-healing soil curing technology called “road liquid,” which is a fly ash-based soil curing agent. This technology is used for the curing of industrial construction waste disposal methods. For the first time, the soil curing agent is mixed into the construction waste along with cement stabilization. Different amounts of mixing are used as controls to evaluate the performance of the curing material after the construction waste is cured. The study focused on the material properties of cured construction waste, specifically examining strength, water resistance, and self-healing properties. The study showed that the curing agent “road liquid” enhanced the strength, water resistance, and selfhealing properties of the cured construction waste at various cement dosages. The 7-day unconfined compressive strength of recycled aggregates with a 5% cement dosage, added with the curing agent “road liquid,” was higher than that of recycled aggregates with a 6% cement dosage without the curing agent “road liquid.” The experimental results show that using this type of granular solid waste as pavement base material is more practical for engineering purposes. The curing agent “road liquid” can enhance the curing effect of recycled aggregate, thereby reducing the need for cementitious materials and achieving cost savings for the project.
