Abstract Concrete, which is now the second most consumed substance in world after water has cement as main ingredient. There a continuous increase pollution due to enormous volumes of CO 2 that are released into atmosphere during production cement. The invention geopolymer concrete proceeded reduce environmental by replacing with supplementary cementitious ingredients such flyash, GGBS, metakao...

Due to the large contribution of cement production towards CO2 emission and rising concerns regarding climate change, substitution with alternative binders has become an established improve sustainability. Aluminosiliceous polymeric materials, known as geopolymer or alkali activated have been proven achieve a performance good even superior ordinary Portland (OPC). Various source materials poten...

Worldwide, it is now known that industrial by-products rich in silicon (Si) and aluminum (Al) can be transformed by alkaline activation into so-called “green concrete”, an efficient sustainable material the field of construction; geopolymer material. In this work, materials produced using fly ash marble dust or blast furnace slag were studied to assess influence these substitutions on performan...

This paper presents a comparative study of the characteristic of unfoamed and foamed geopolymers after exposure to elevated temperatures (200-800 °C). Unfoamed geopolymers were produced with Class F fly ash and sodium hydroxide and liquid sodium silicate. Porous geopolymers were prepared by foaming with hydrogen peroxide. Unfoamed geopolymers possessed excellent strength of 44.2 MPa and degrade...

This study focuses on calcined kaolin, commercial sodium silicate, and Amazonian bamboo to make geopolymer. The durability of geopolymer matrix (GP) fiber composite (GPBF) materials was analyzed by studying the resistance exposure sulfuric hydrochloric acids at concentrations from 0 15 wt%, testing two different geometry samples. microstructure raw investigated X-ray fluorescence scanning elect...

The impact of different parameters on the compressive strength geopolymer synthesized from clay and bagasse bottom ash is reported. Geopolymer was thermally activated using sodium silicate hydroxide as activator. maximum dissolution alumina silica maintaining alkali conditions studied. resulting under studied for strength. Different characterizations were carried out analytical instruments. res...
