Effect of Micro Lime on The Ambient Cured Sugarcane Bagasse Ash-Based Geopolymer Concrete

Jurnal Teknik Sipil, 2023
Geopolymer concrete has been the ideal replacement for Ordinary Portland cement concrete in producing green concrete. The binder in geopolymer concrete is a cementitious paste made from amorphous Aluminosilicate and activated by an Alkaline solution. The

Encapsulation of Cs/Sr contaminated clinoptilolite in geopolymers produced from metakaolin [PDF]

, 2015
The encapsulation of caesium (Cs) and strontium (Sr) contaminated clinoptilolite in Na and K based metakaolin geopolymers is reported. When Cs or Sr loaded clinoptilolite is mixed with a metakaolin geopolymer paste, the high pH of the activating solution

Geopolymer binder for pervious concrete [PDF]

Journal of the Croatian Association of Civil Engineers, 2021
Construction of pervious concrete (PC) pavements is an exclusive and efficient measure for solving environmental problems while also contributing to sustainability. Pervious concrete enables rainwater to percolate into soil thus reducing the storm water runoff and assisting in ground water recharge.

GEOPOLYMER CONCRETE- A REVIEW [PDF]

International Journal of Engineering Sciences & Emerging Technologies, 2012
Concrete is the world’s most versatile, durable and reliable construction material. Next to water, concrete is the most used material, which required large quantities of Portland Cement. Ordinary Portland Cement production is the second only to the automobile as the major generator of carbon di oxide, which polluted the atmosphere.

Self-compacting geopolymer concrete

International journal of health sciences, 2022
Self-compacting geopolymer concrete (SCGC) is a novel material. and a modern high-performance concrete that doesn’t require Ordinary Portland cement and additional compaction. SCGC is made up of industrial byproducts, with high Alumina and Silica composition, and uses  super plasticizer as a binder for matrix formation and strength.
