Abstract

Abstract

Geopolymer concrete (GPC) is gaining attention as a sustainable alternative to ordinary Portland cement (OPC) due to its potential to reduce the environmental impact of cement production, which accounts for roughly 7% of global CO2 emissions. This study investigates the use of processed fly ash and alccofine as key ingredients in GPC to improve its workability and compressive strength. Experimental tests were conducted to evaluate the effects of different proportions of fly ash, alccofine content, and curing methods on the concrete’s performance. The results demonstrate that processed fly ash significantly enhances both the slump values, and the early-age compressive strength of GPC compared to unprocessed fly ash. Furthermore, the inclusion of alccofine boosts workability by up to 200%, while also improving compressive strength. Under heat curing conditions, compressive strength values reached as high as 73 MPa, while ambient curing achieved up to 32 MPa by the 28-day mark. This indicates that GPC can meet the compressive strength requirements of M25 grade concrete, even under ambient curing conditions. The research highlights the potential of GPC as a sustainable construction material, offering significant environmental benefits by repurposing industrial by-products like fly ash and alccofine. Additionally, GPC’s ability to achieve high compressive strength under ambient conditions makes it a viable option for a range of construction applications. This study contributes to the growing body of knowledge on green construction materials, presenting GPC as an effective solution for reducing the carbon footprint of the construction industry and advancing sustainable building practices.
