Utilization of Industrial By-Products/Waste to Manufacture Geopolymer Cement/Concrete

There has been a significant movement in the past decades to develop alternative sustainable building material such as geopolymer cement/concrete control CO2 emission. Industrial waste contains pozzolanic minerals that fulfil requirements alumino-silicate based geopolymer. For example, industrial red mud, fly ash, GBFS/GGBS (granulated blast furnace slag/ground granulated slag), rice husk ash (RHA), and bagasse consist of contribute manufacturing cement/concrete. A literature review was carried out study different waste/by-products their chemical composition, which is vital for producing cement, discuss mechanical properties manufactured using waste/by-products. The durability, financial benefits sustainability aspects have highlighted. As per experimental results from literature, cited successfully utilized synthesis dry or wet geopolymers. revealed use RHA concrete resulted high compressive strength (i.e., 50 MPa–70 MPa). (>70 MPa) achievement, most slag ash-based synergy with nano processed shown good environmental resistant. alkali-activated slag, mud binders give better durability performance compared other waste. Based on indicators, geopolymers developed positive impact environment, society economy.
