Pre-mixed fluidized solidified soil (PFSS) has the advantages of pumpability, convenient construction, and a short setting time. This paper took the excavated loess in Fuzhou as the research object and used cement-fly-ash-ground granulated blast furnace slag-carbide slag as a composite geopolymer system (CFGC) to synthesize PFSS. This study investigated the fluidity and mechanical strength of PFSS under different water-solid ratios and curing agent dosages; finally, the microstructure of the composite geopolymer system-pre-mixed fluidized solidified soil (CFGC-PFSS) was characterized.

The grouting technique is an efficient method for enhancing the stability of cracked slopes through the use of grouting materials. Conventional cement-based grouting materials are costly, energy-intensive, and environmentally damaging. Additionally, cement-hardening slurry is prone to cracks between the slurry and the rock.

Article Synopsis
- The study focuses on creating iron ore tailings-blast furnace slag (IOT-BFS)-based geopolymers with adjustable setting times and high compressive strength for civil engineering applications.
- Key factors influencing the setting time include the content of iron ore tailings, alkali content, liquid-solid ratio, and the modulus of alkaline activators, which were thoroughly analyzed.
- Results show that adjusting the modulus of the alkaline activator significantly affects the setting time, allowing control from around 3 minutes to 108 minutes, enabling tailored geopolymers for diverse construction needs.

Over the years, ordinary Portland cement (OPC) has been used to meet growing demands of land and housing facilities arising out of population overburdens. It is well documented that OPCs, besides their outstanding qualities as building materials, are also significant contributors to global greenhouse gases (GHG). Consequently, recent years have noticed an emerging interest in the search for alternatives to Portland cement-based binders.

Article Synopsis
- * PTWA was tested as a partial replacement for ordinary Portland cement in concrete by varying its ratio while keeping ground blast furnace slag constant, and a series of experiments analyzed both mineralogical properties and mechanical performance over time.
- * Results showed that while using PTWA reduced setting times of the concrete mixtures, it also led to decreased overall performance compared to standard mixes, suggesting a complicated relationship that could potentially benefit the environment when combined with other materials like GBFS.
