Figure 5

Typical uniaxial tensile stress–strain curves for reinforced foamed concrete mixtures with different fiber-reinforcements and volume fractions. A stress–strain curve of the PFC is included in each figure for comparison purposes: (a) untreated henequen fiber; (b) treated henequen fiber and (c) PP fiber.
