“…It was recognized as a high performance concrete due to its high durability, passing ability, and flowability (Okamura and Ouchi 2003), further, homogeneity, resistance to segregation were also highly recognized later (Benabed et al 2012). In general, to examine the mechanism of self-compacting concrete (SCC) a deep understanding of the rheological properties of self-compacting mortar (SCM) is mandatory (Mayhoub et al 2021). The relative flow area and relative flow speed are the initial parameters to investigate the flow properties of SCC (Okamura and Ouchi 2003).…”

“…For the Na08 specimen, its strength can reach up to 58.63 MPa after 28 days of curing. This is believed to be due to the higher molarity of NaOH can lead to more Si and Al ions dissolved from GGBFS and form more precursors that is required for geopolymerization [33][34][35].…”

The objective of this study is to use the geopolymer technique to solidify/stabilize heavy metal contaminated soil. There are over 739,700 square meters of heavy-metal-contaminated sites in Taiwan; most sites are soil farmlands. These heavy metal contaminants in soil can also infiltrate into groundwater and cause more serious pollution problems. This study explores the possibility of using the geopolymer technique to solidify heavy metal contaminated soil (CS), stabilize heavy metal, and produce good mechanical and physical properties. The ground granulated blast furnace slag (GGBFS) was activated by an alkali solution to form a geopolymer binder that can be used to solidify CS and stabilize the heavy metal. The effect of GGBFS and CS mixing ratio on the mechanical and physical properties and the TCLP test was investigated. The test results show that the compressive strength of specimens made with a 1.5 CS/GGBFS ratio can reach 46.61 MPa and 47.66 MPa after curing for 14 and 28 days, respectively. TCLP tests show only 2 ppm Cu was detected from a geopolymer-treated contaminated soil sample. The influence of alkali solution, such as the molarity of the NaOH, SiO2/Na2O, and SiO2/Al2O3 molar ratio, were also evaluated. The specimens prepared with 8 M NaOH, 0.96 SiO2/Na2O, and 1.28 SiO2/Al2O3 molar ratio alkali solution have a compressive strength of 51.74 MPa and 58.63 MPa after 14 and 28 days of curing. The TCLP tests show no heavy metal ions leached from the sample.

“…The mixes from Refs. [ 38 , 49 ] present a blend of both worlds. They experiment with combinations of OPC and potential geopolymeric components, perhaps aiming to harness the benefits of both materials.…”
