Optimisation Approach and Influence of Composition and Curing Parameters on Algerian Geopolymer Paste Compressive Strength Based on Metakaolin and Slag Local Materials| Chapter 8 | Current Overview on Science and Technology Research Vol. 10

 The soluble base-activated cement has existed proposed as an alternative to Portland cement and has proved good physical, machinelike, and durability features 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 brimming factorial design with two levels to comment how the variation of these limits promotes the modifications on the new and hardened properties of presented geopolymer. Then, we analysed the optimisation of the main parameter effect, the interplays, and the predicted reaction 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 kiln OT(60- 100)C° and the curing period CT (6- 48)h were considered for each consolidation of MK/S: [(50 % MK / 50%S), ( 80 % MK /20%S ) and ( 100 % MK/ 0 % S)].

Influence of Additives on the Structure and Properties of Gypsum-Cement-Pozzolanic Binder | Chapter 01| Research Developments in Science and Technology Vol. 5

 Gypsum binders aren't known for their strength or water resistance. This precludes the usage of these binders in high-humidity environments. The range of gypsum binders for constructing dry building mixes and structural parts of low-rise buildings can be expanded by changing the structure of gypsum-cement-pozzolanic binders. The study's goal was to create a long-lasting, water-resistant gypsum binder. The results of the research demonstrate that in the presence of functional additives, the nature of hydration neoplasm crystallisation changes, resulting in a change in the characteristics of the cured binder. It was feasible to build strong, water-resistant gypsum binders by studying the effects of individual and complex additions on the characteristics of the gypsum-cement-pozzolanic binder.
