“…Recently, many researchers have demonstrated that a variety of aluminosilicate waste materials such as FA, bottom ash (BA), and GGBFS may be used to produce geopolymer bricks with the application of geopolymerization [5,[27][28][29][30]. Ibrahim et al [5] studied the processing and characterization of FA-based geopolymer bricks that were produced using a mixture of NaOH and Na 2 SiO 3 as an activator and then investigated the effects of curing conditions on the properties of these bricks.…”

“…In addition, the optimum temperature and duration for curing were identified as 608C and 24 h, respectively. Abdullah et al [29] evaluated the performance of FA-based geopolymeric masonry bricks. The brick samples were prepared using various FA-to-sand ratios (1:2-1:5), a Na 2 SiO 3 -to-NaOH ratio of 2.5, and an FA-to-activator solution of 2.0.…”

This research compares the mechanical‐microstructural properties and thermal conductivity of the solid, green construction bricks that contain different percentages of sodium‐hydroxide‐activated residual rice husk ash and class‐F fly ash. The brick specimens were prepared following the guidelines of Vietnamese national standard in term of mixing, forming, and curing. Various percentages of rice husk ash (0%, 10%, 20%, 30%, 40%, and 50%) were added to a standard brick mixture in order to evaluate the influence of rice husk ash content on the strength development, void volume, water absorption capacity, bulk density, and thermal conductivity of the hardened bricks. Moreover, scanning electron microscopy was used to characterize surface morphologies of the brick samples. Further, the suitability of using a binder of rice husk ash and fly ash to produce alkali‐activated construction bricks was investigated. The bricks that were produced demonstrated generally good engineering performance and conformed to the relevant Vietnamese codes. Of particular note, the addition of rice husk ash influenced the properties of the bricks significantly, with brick strength peaking at a rice husk ash content of 10% and decreasing progressively at higher percentages. The findings from the present study support the efficacy of using a binder that contains rice husk ash and fly ash to produce green alkali‐activated construction bricks. © 2017 American Institute of Chemical Engineers Environ Prog, 37: 1647–1656, 2018

“…According to Temunjim [77] and Garcia [78] the presence of calcium has a positive effect on the compressive strength of the samples cured at ambient temperature by forming amorphous structured Ca-Al-Si gel, the porosity of the microstructure decreased and the formed gel strengthens the final product. The reached compressive strength of G 0.85 700 at 28 days can be suitable for an application as geopolymeric bricks can satisfying the requirement of BS 6073 for compressive strength !7 MPa [79].…”

The phosphate ore extraction activities often generate serious environmental problems, particularly those engendered by the phosphate washing waste. The waste was characterized by X ray fluorescence. The powder was calcined at 700°C. The calcined and uncalcined samples were then investigated by means of X-ray powder diffraction (XRD). The calcined PWW was activated with sodium hydroxide and sodium silicate to produce geopolymeric materials. The reached results prove to reveal that the present phases in the powder appeared to have a remarkable effect on the result of compressive strength.
