Mechanical Properties of High-Strength Pervious Concrete with Steel Fiber or Glass Fiber

Pervious concrete (also called porous concrete) is one of the most promising sustainable and green building materials today. This study examined high-strength pervious ordinary-strength reinforced with steel fiber or glass fiber. A total fifteen mixtures normal- concretes were used. The goal that 28-day compressive strength be above 42 MPa porosity as close to 15% possible achieve technical specifications. Both (1%, 2%) (0.25%, 0.5%) investigated in water permeability, porosity, strength, flexural elastic modulus, toughness tests. test results show both ordinary fibers added, permeability coefficient are increased compared control group. for high-strength, fiber-reinforced two aggregate sizes meets requirements ACI specification structural concrete. In addition, specimen H1-S2 (2% fiber) has highest 52.8 at age 28 days. also increases age. However, did not follow this trend due large variation quality different mixtures. have a certain degree improvement toughness, effect better After reaches peak value, there still about 30% bearing capacity, it gradually decreases until completely destroyed.
