Compressive Mechanical Properties and Economic Performance of Steel-PVA Hybrid Fiber Cement-Based Composites
Due to the high cost of fiber reinforced ductile cement-based composites (ECC)it has not been promoted in practical engineering applications. Steel fiber was added to the traditional ECC systemand Nissan PVA fiber was replaced by domestic PVA fiber according to different volume fraction (0%25%50%75%100%) to prepare cost-effective steel-PVA hybrid fiber reinforced ductile cement-based composites. The uniaxial compressive mechanical properties of hybrid fiber reinforced ductile cement-based composites were studied by cube axial compressive test. The results show that with the increase of domestic PVA fiberthe compressive strength of steel-PVA hybrid fiber cement-based composites decreases first and then increasesand the compressive toughness index increases first and then decreaseswhile the peak strain increases significantly. Compared with ordinary cement-based materialssteel-PVA hybrid fiber cement-based composites have better integrity and ductility. Based on the compressive properties and material cost of the compositesthe domestic PVA fiber can replace the Nissan PVA fiber to configure the steel-PVA hybrid fiber cement-based composites to maximize the functional value and economic value.
