    3. MIX DESIGN 3.1 Design of Geopolymer Concrete Mixtures: In the mix design of geopolymer concrete the role and the influence of aggregates are considered to be the same as in the case of Portland cement concrete. The mass of combined aggregates may be taken to be between 75% and 80% of the mass of geopolymer concrete. Coarse and fine aggregate together were taken as 77% of entire mixture by mass. Fine aggregate was taken 30% of total aggregate. Fly ash and alkaline liquids was taken 23% of…

    In the paper, FePO4 was studied in through neutron powder diffraction across a wide range of temperatures, and was found to have 2 states in general, the α (alpha) phase and β ( beta ) phase. The alpha phase exhibits a tetrahedral structure, which is similar to alpha quartz, and this occurs during generally low temperatures. In the case of this paper, the temperatures experimented on were between 294K and 1073K. The beta phase, however, is denser and exhibits a octahedral structure. The…

    The past chapter proposed the continuous floating constraint and buckling column concept. In this chapter, a test setup is proposed to investigate its loading nature and validate the concept. A series of tests are performed, and the results are presented and discussed. The results of the tests conducted in this chapter will serve as measures in assessing the strengths and flaws of the initial concept, and point towards potential solutions. This group of tests varied two geometric parameters:…
