GEOPOLYMER FORMATION ANALYSIS

Inorganic polymer concretes, or ‘geopolymers,’ have become engineering materials with the potential to become an important element in environmentally sustainable construction and building products industry. These materials are commonly formed by alkali activation of industrial aluminosilicate waste materials such as fly ash and blast furnace slag. Geopolymer concrete production emits almost zero greenhouse gases which is CO2 when compared to traditional concretes or ordinary Portland Cement (OPC). With correct mixture and formulation development, geopolymeric materials derived from fly ash or other materials can exhibit superior chemical and mechanical properties to ordinary Portland cement (OPC), and be highly cost effective. The present production of geopolymer concrete include low or high strength concretes with good resistance to chloride penetration, fire and/or acid resistant coatings, and waste immobilization solutions for the chemical industries. The study of geopolymer formation will contribute to the greater understanding on geopolymer strength attributes and will helps the engineers to adapt the parameters for suitability of geopolymer production. Later in this project, the subject of geopolymer will be discuss further and several experiment will be conduct to study the geopolymerization process with certain parameter setting. The research will focusing on three main parameter which are study on addition of additives on geopolymer formation, different alkali-activator, and solid loading varition. The result will later tested using Vicat Needle, and will be describe more using Avrami Kinetic Theory
