Answer» Correct option is (a) True To explain: A thin and short fiber, for example short, hair-shaped glass fiber, is only effective during the first hours after pouring the CONCRETE (its function is to reduce cracking while the concrete is stiffening), but it will not increase the concrete tensile STRENGTH. A normal-size fiber for European SHOTCRETE (1 mm DIAMETER, 45 mm length—steel or PLASTIC) will increase the concrete’s tensile strength.
