ABSTRACT:
Concrete and mortar composites can be made with two or more sizes of fibers therein. The different sized fibers can be used to adjust the toughness and reliability of the composite material. The different sized fibers can also be used to increase the deflection of concrete or mortar compositions. The variable length of fibers provide for smaller fibers to exist in corners for more strength in smaller spaces. Different mixes of sizes of fibers can also adjust the stiffness of a concrete or mortar composite material. The fibers can be made from a variety of materials, lengths, shapes, aspect ratios or diameters. The fibers can make up variable portions of the composition. Mixing different aspect ratios of fibers together can be used to prevent clumping or balling of the fibers. Mixing of different modulus of elasticity fibers in different ratios can add to the toughness and strength of the composite.
