Geopolymer Concrete a Sustainable Concrete for Future Construction

EasyChair Preprint 8215

Abstract

The production of the cement concrete industry has grown in this modern world and is considered one of the major contributors to global pollution. The production of cement used as binder requires a high-temperature combustion process which contributes to the increase of the amount of CO2 in the atmosphere leading to one of the major threats to the planet (climate change) and the consumption of natural resources. Many countries begin to impose carbon taxes as raw materials deplete over time. To reduce and eliminate greenhouse gas emissions, numerous studies have been conducted to develop an innovative and environmentally beneficial building material names Geopolymer concrete. It is vital to replace cement with a by-product substance abundant in silicon and aluminium such as fly ash, rice husk ash, silica fume, GGBS, etc. activated by a high alkaline solution to bind loose aggregates, fine aggregates, and other unreacted materials in geopolymer concrete in order to improve the qualities of concrete and reduce natural resource uses. The current study focused on the impact of various parameters such as molarity of sodium hydroxide (8-16M), and curing temperature(30-900C) on different mechanical properties such as workability, compressive strength and tensile strength of geopolymer concrete.

Keyphrases: Geopolymer concrete, NaOH Molarity, compressive strength, super-plasticizers., tensile strength
