Abstract Research has shown that adding supplementary cementitious materials (SCMs), such as fly ash (FA) and slag (SL), to concrete improves its mechanical durability properties up certain limits. However, the long-term performance of made with FA SL is not fully known. This study investigates impact on (up 900 days) concrete. The specimens were six replacement percentages (0, 10, 20, 30, 45 60 by weight) ordinary Portland cement (OPC). short-term fresh hardened all mixes assessed after 14, 28, 60, 90 days water curing. After 120, 365, 730, curing, was investigated for 100% OPC (control), 30% FA, concretes. At 28 days, no significant difference in strength development observed containing than control (100% OPC). In contrast, a remarkable enhancement registered at tests. Likewise, showed lowest porosity absorption control. prepared gradually rises over time (from 14 compared With increasing age, reduction capillary seen days).

This study develops an environmentally friendly geopolymer concrete (GPC) using wastepaper ash (WPA) and high-density polyethylene (HDPE) granules, addressing environmental challenges such as HDPE disposal CO2emissions from cement production. WPA was produced by incinerating at 550 °C for one hour used a partial replacement MK in ratios of 10%, 20%, 30%, 40%, 50%, 100%, while granules replaced river sand 1% to 5%. The results showed that the use 30% resulted compressive strength (CS) 35.38 MPa, which significantly higher than control sample's CS 31.62 MPa. increased slump due lower water demand. combination 3% further enhanced mechanical properties, resulting 36.54 representing 15.5% increase over control. However, addition reduced slump, attributed friction granules. Advanced analyses, including SEM, EDX, XRD, confirmed refined pore structure geopolymerization treated GPC. It is novel optimize waste products production MK-based Doi: 10.28991/CEJ-SP2024-010-011 Full Text: PDF
