Leaching of F-type fly Ash Based Geopolymers

Procedia Engineering, 2012
AbstractGeopolymers are the synthetic analogues of natural zeolitic materials. Geopolymeric materials possess excellent mechanical properties, including fire and acid resistance. These properties make geopolymers an alternative construction material compared to Portland cement.

Investigating the Mechanical and Microstructural Properties With Machine Learning Optimization of Recycled Eco‐Friendly PET Modified Concrete

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
Over the past decades, studies have demonstrated the effectiveness of polyethylene (PE) and PE terephthalate (PET) as an alternative to aggregates in enhancing concrete performance. This research aims to predict the compressive strength (CS) of PE and PET‐incorporated concrete by evaluating the influence of key factors, including cement content, PET ...

Factors influencing strength and setting time of fly ash based-geopolymer paste

MATEC Web of Conferences, 2017
In general, fly ash is often used as a binder in geopolymer mixture. In this paper, seven samples of fly ash were collected from five Indonesian power plants. The variation of fly ash may depend upon many factors.
