Adding polypropylene fibers to concrete is an effective way to reduce concrete cracking. The supporting system formed by fibers in concrete produces a secondary strengthening effect, which can greatly improve the crack resistance, improve the impermeability and impact resistance of concrete.
Do you know what typical engineering data should we check when choosing fibers?
Distance between the outer ends of the fiber.
For Polypropylene Synthetic Microfiber, TenaBrix® offers regular size of 6mm, 12mm, 18mm, and 19mm, we also provide single cut length.
For Polypropylene Synthetic Macrofiber, the regular size is 48mm, 50mm, 51mm, and 54mm. TenaBrix® fiber products can be used in all types of concrete applications to control plastic shrinkage and settlement cracking.
Diameter of a circle with an area equal to the mean cross sectional area of the fiber. For circular fibers, the equivalent diameter is equal to the diameter of the fibers.
TenaBrix® Micro fibers: < 0,30 mm in diameter; Mono-filamented TenaBrix® Macro fibers: > 0,30 mm in diameter.
The ratio of length to the equivalent diameter of the fiber
TenaBrix® 100 % virgin homopolymer polypropylene multifilament (monofilament) fibers Aspect Ratio: Varies from 250 to 630.
Specific outer configuration of the fiber, both in the longitudinal direction and in the shape of the cross section and also the possible surface coatings and or bundling of the fibers.
Stress corresponds to the maximum force a fiber can resist. The tensile strength is calculated by dividing the maximum force a fiber can resist by the mean cross-sectional area of the fiber.
Elongation of the fiber is defined as the ratio of the length change of the fiber to the initial length expressed as a percentage.
NOTE: The length change should be measured on the fiber itself.
The initial slope of the tensile stress versus elongation curve.
The temperature at which a polymer becomes liquid.
Mass per unit length of yarn or filament expressed in tex or its multiples or submultiples.
The temperature at which combustion is initiated.
