Green high-performance fiber-reinforced cement (GHPFRC) matrix composite is prepared by mixing matrix composites like slurry, mortar, or concrete with reinforcing materials like metal or inorganic nonmetal fiber, synthetic fiber, or natural organic fiber by a certain method. This composite is more energy-efficient, ductile, low-carbon, economic, and environmentally friendly than ordinary concrete. However, the performance of GHPFRC matrix composite has not been fully studied. The existing research only deals with the seismic performance and fire resistance of the material, failing to systematically discuss the optimal mix ratio. To solve the problem, this paper presents an optimization strategy for multielement GHPFRC matrix composite, and carries out multiple tests on its basic mechanical performance, toughness, impact resistance, shrinkage cracking, dry shrinkage performance, and durability. The test data on various indices verify the superior performance of the prepared multielement GHPFRC matrix composite. Further, the optimal mix ratio of the material was determined as: 60% cement, 30% fly ash, and 10% silica ash, with the water-cement ratio of 0.4, water reducer dosage of 1.5%, and quartz sand dosage of 500g.
