Abstract

The invention relates to a method for determining tensile strength of blended fibers in concrete, on a unit cross section, the minimum tensile strength provided by the fibers for the concrete is F, and the F has the following two forms: 1): 2): the formula, n represents the number of the fibers on the unit cross section, n is a positive integer which is not less than 1, F represents the tensile strength of a single fiber, n in the formula 1 is an odd number, and n in the formula 2 is an even number. According to the method, the minimum tensile resistance provided by the n fibers on the unit cross section can be calculated through the formula, so that the technical problem that the tensile resistance of the blended fibers in the concrete cannot be determined in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of concrete production, in particular to a method for determining the tensile strength of fibers mixed in concrete. Background technique [0002] Concrete is a commonly used building material. Common concretes include asphalt concrete and cement concrete. Asphalt concrete is mixed with gravel, asphalt and other materials. Cement concrete is mixed with gravel, cement and other materials. And the cement in cement concrete can become a gelling agent. [0003] In the prior art, in order to improve the tensile strength of concrete, the general practice is to mix fibers into the corresponding concrete. [0004] The problem existing in the prior art is that the length of the fibers mixed into the concrete is not easy to determine, and is generally added by experience. In fact, if the fiber length is too short, the force between the fibers and the concrete, that is, the gripping force is not enough. Then it will n...
