GEOPOLYMER CONCRETE- A SUSTAINABLE CONCRETE FOR FUTURE CONSTRUCTION

By Er. MATUTU YOMBI ANNE & Dr. JADGISH CHAND

The manufacture of cement and concrete has increased in the contemporary era and is one of the primary sources of pollution in the globe. The high-temperature combustion process necessary for the manufacturing of cement, which is used as a binder, increases the atmospheric CO2 concentration, causing one of the biggest risks to the globe (climate change), and diminish the natural resources. As the supply of raw resources declines over time, several nations start enacting carbon taxes. Numerous research have been undertaken to produce an innovative and ecologically advantageous construction material known as Geopolymer concrete(GC) which is advantageous for the environment and helps minimise and eliminate greenhouse gas emissions. To improve concrete quality and reduce natural resource use, it' s critical to substitute cement with a by-product substance rich in silicon and aluminium such as fly ash(FA), rice husk ash(RHA), silica fume(SF), GGBS and others, activated by a high alkaline solution to hold together loose aggregates, fine aggregates, and other unreacted materials in geopolymer concrete. The goal of the current study was to provide a thorough review of geopolymer concrete, to suggest a method for designing a geopolymer concrete mix based on the amount and fineness of fly ash, and to examine the effects of various parameters, including the molarity of sodium hydroxide and curing temperature on various mechanical properties, including workability, compressive strength, and tensile strength. The findings indicated that a molarity of 14M at 90 0 C after 28 days of testing produced the greater strength.
