In recent years, there has been a significant increase in the generation of glass fiber-reinforced plastic (GFRP) waste. Traditional disposal methods have led to the wastage of resources and elevated carbon emission rates. Therefore, recycled glass fiber reinforced plastic powder was utilized to synergistically substitute a portion of the cement with silica fume, aiming to produce green cementitious composites. The study focuses on crucial properties such as strength, drying shrinkage, and fluidity. XRD, TG/DTG, and FT-IR analyses were conducted to clarify the hydration process of the composites, while MIP and water porosity measurements assessed the modifications in pore structure across various sample groups. The results demonstrate that the compressive strength of the new composite substantially increases by approximately 40 %, while cement consumption decreases by 30 %. This study presents a pioneering utilization of recycled glass fiber-reinforced plastic (RGFRP) and an innovative method for producing eco-friendly cementitious composites.
