A Bibliographic Historical Analysis on Geopolymer as a Substitute for Portland Cement

Abstract

Growing concern about environmental degradation has expanded the search for new technologies that could ensure sustainable development. In civil construction, new materials have emerged as alternatives to reduce the impact of the activity on the environment, one of them is the geopolymer. This material, which can be characterized as a stable and synthesized composite of aluminosilicate materials, has emerged as a potential substitute for Portland cement because it presents similar characteristics of initial strength and good mechanical performance, but without the high emission of carbon dioxide (CO2) to obtaining it. This work brings a bibliographic analysis on geopolymer, it is intended to disseminate knowledge as of the state of the art on geopolymer as cement substitute.

Taguchi- Grey relational analysis for Optimizing the Compressive Strength and Porosity of Metakaolin-Based Geopolymer

“…For compressive strength and porosity, the average value of the experimentally obtained results are given in Table 3. This raw data can be transformed into S/N ratio by using Equation (1). According to L25 orthogonal array the corresponding S/N ratio values for experimental parametric setting are summarized in Table 4.…”

“…Joseph Davidovits is considered the first to formulate the geopolymer term in1970s [1]. Geopolymers refer to the three-dimensional aluminosilicates cementitious material that can be produced by the precipitation, polycondensation and dissolution of the aluminosilicates origin [2].…”
