چکیده
To investigate the mechanical properties of polyvinyl-alcohol (PVA)-fiber-reinforced rubber concrete, 13 groups PVA rubber/concrete specimens with volume fractions 0%, 0.5 vol%, 1.0 and 1.5 vol% particles replacement sand ratios 10%, 20%, 30% were prepared, uniaxial compression full curve test was performed. The findings indicate that bridging effect PVA, as well synergistic particles, can improve compressive failure demonstrates obvious ductile characteristics. Furthermore, has a better impact on concrete’s bearing capacity, crack propagation surface, strength in latter stages. PVA-fiber-reinforced concrete is thought to be six-phase composite made up aggregate phase, mortar matrix, fiber, aggregate–mortar interface, rubber–mortar interface mesoscale. simulate entire process varying rubber/content from integrity damage cracking, meso-numerical model constructed. simulation results are good agreement, demonstrating validity mesomodel offering theoretical foundation for structural analysis design this type concrete.

The paper presents the results of casting and testing of 264 GFRC specimens. The glass fibers were 25 mm long, with the aspect ratio (L/D) ranging between 1250 and 3570. The parameters studied were the ratio (by weight) of fibers to cement, i.e. F/C=0%, 1.5%, 3%, and 4.5%, and the ratio of coarse to fine aggregates (gravel to sand), i.e. G/S=1.1, 0.7 and 0.2. In total, 12 mix designs were selec...
