Title

Cold sintering assisted polycondensation of iron-rich aluminosilicates geopolymers

Abstract

The cold sintering is an innovative process for the design of energy efficient and sustainable engineering matrices for various applications. The intrinsic properties of iron-rich aluminosilicates present in tropical area of the world are in line with the principle climate technology and offer unique chance for the development of infrastructures while respecting the UN objectives of the sustainable development. The consolidation of the natural iron-rich aluminosilicates is enhanced using geopolymerisation, external pressure and temperature in a ultra-low energy sintering context. Optimized formulations of laterite and Rice Husk Ash (RHA) are used to investigate the effects of the external pressure and temperature on the porosity, phases composition development, micromechanics and microstructure.
