Green Concrete Geopolymers As A New Concept In Sustainable Green Building "Zero Cement"
Authors(5) :-H. E. Fouad, W. H. Soufy, H. A. EL-Ghazaly, M. A. Abd-El-Aziz A, S. Abd Elatty Green concrete can be defined as the concrete with the material as a partial or complete replacement for cement or fine or coarse aggregates. The substitution material can be of waste or residual product in the manufacturing process. Green concrete should follow reduce, reuse and recycle technique or any two processes in the concrete technology. The three major objective behind green concept in concrete is to reduce greenhouse gas emission (carbon dioxide emission from cement industry, as one ton of cement manufacturing process emits one ton of carbon dioxide), secondly to reduce the use of natural resources such as limestone, shale, clay, natural river sand, natural rocks that are being consume for the development of human mankind that are not given back to the earth, thirdly use of waste materials in concrete that also prevents the large area of land that is used for the storage of waste materials that results in the air, land and water pollution.
Geopolymers cement concretes’ (GPCC) are Inorganic polymer composites, which are prospective concretes with the potential to form a substantial element of an environmentally sustainable construction by replacing/supplementing the conventional concretes. GPCC have high strength, with good resistance fire attack, etc. These are commonly formed by alkali activation of industrial aluminosilicate waste materials such as FA and GGBS, and have a very small Greenhouse footprint when compared to traditional concretes. The sustainability of green concrete resulted from the development without destruction natural resources.
Aim of this work mainly explain the preparation of Geopolymers and the different factor that effect on the specifications of concrete. Types of activator, particles size and chemical composition of silica alumina waste materials and setting condition of concrete. Geo polymer concrete gets advantage in the resistivity to change in mechanical and physical characterization at high temperature compared to the traditional concrete.
