Abstract

Abstract:

This study aims to systematically investigate the mechanical properties and micro-mechanisms of cementitious composites reinforced with glass powder （GP） and modified polypropylene fibers， determine the optimal mix proportion through multi-index optimization， and ultimately develop an eco-friendly high-performance fiber-reinforced cementitious composite. The experiment employed varying proportion of GP as a replacement for fly ash， along with modified polypropylene fibers of 6， 12， and 20 mm lengths in single doping or pairwise hybrid combinations. The workability and mechanical properties of the fiber-reinforced cementitious composites were systematically investigated through flowability tests， flexural tests， compressive tests， tensile tests， and four-point bending tests. SEM was utilized to explore the microstructural mechanisms by which GP and modified polypropylene fibers enhance the performance of these composites. Finally， a multi-factor grey relational decision-making model was applied to determine the optimal mix proportion. The results demonstrate that increasing the GP replacement ratio significantly improves the mechanical properties of the fiber-reinforced cementitious composites. At a 100% replacement rate of GP， the flexural strength of specimens increases by up to 79.28%， compressive strength by up to 40.72%， tensile strength by up to 80.00%， and the toughness index reaches a maximum of 30.962. SEM analysis reveals that GP particles tightly bond with hydration products and embed densely within the matrix， markedly enhancing the compactness of the cementitious composite and thereby improving its mechanical properties. Based on the grey relational decision-making model， the optimal formulation is identified as 100% GP replacement combined with 20 mm modified polypropylene fibers， which exhibits significant overall performance enhancement.
