Optimisation Approach and Influence of Composition and Curing Parameters on Algerian Geopolymer Paste Compressive Strength Based on Metakaolin and Slag Local Materials

The salt-activated cement has happened proposed as an alternative to Portland cement and has proved good physical, machinelike, and durability characteristics as well as low incidental impacts.This work aims to study the production of Metakaolin/Blast kiln slag (MK/S) located geopolymer. We investigated the influence of metakaolin content, the concentration in the soluble solution, the SiO2/Na2O a hard bony structure in the jaws of vertebrates ratio, the healing temperature, and the curing occasion using a thorough factorial design with two levels to obey how the variation of these limits promotes the modifications on the new and hardened properties of caused geopolymer. Then, we analysed the optimisation of the main parameter effect, the interplays, and the predicted answer of the generated model using factorial design in mathematical software JMP Trial 16.The limits such as something that chops ratio MR (1.5 – 2), the density of solutionDS (1.3 -1.4) g/cm3, the healing temperature of microwave oven OT(60- 100)C° and the curing occasion CT (6- 48)h were considered for each blend of MK/S: [(50 % MK / 50%S), ( 80 % MK /20%S ) and ( 100 % MK/ 0 % S)].
