Abstract EN
A huge amount of carbon dioxide is released in the Portland cement production process.
A large quantity of greenhouse gases is produced because of the significant amount of energy consumption via making bricks through firing.
Using the pozzolanic sources containing the aluminosilicate and alkaline reagents, a new type of green materials called geopolymeric materials is produced with quite lower environmental hazards.
The use of laterite as an iron-rich aluminosilicate material has a high potential for the building materials.
In this study, the effect of the curing temperature and characteristics of the alkaline reagent including the concentration of sodium hydroxide solution and the water-glass to sodium hydroxide mass mixing ratio on the mechanical strength of the lateritebased, oven-cured geopolymer samples was investigated.
The results showed that the curing temperature had a significant effect on the compressive strength of the laterite-based geopolymer samples, so that with a 15°C change at the curing temperature, the compressive strength of the samples could be multiplied, and a sharp increase in the mechanical strength could occur.
Also, according to the results of this study, the 6 M sodium hydroxide is recommended for the construction of the laterite-based geopolymer materials with low cost and relatively high strength, and for the construction of higher-strength building materials, the 14 M sodium hydroxide is recommended.
