A method for preparing high-strength concrete using waste fibers

Abstract

The invention provides a method for preparing high-strength concrete by using waste fibers. The operation is completed by the cooperation of the bottom frame, the connecting frame, the stirring device, the electric turntable, the rotating frame, the stirring paddle, the sealing cover and the blowing device. The traditional mixing method usually directly mixes concrete slurry with fibers and mixes directly, but because the fibers are light and thin, putting a bunch of fibers into the concrete slurry at the same time is often difficult to mix evenly in the later mixing process, and there are often The fiber is attached to the surface layer and shallow layer of the concrete slurry, but not mixed into the inner layer, resulting in different strengths of various parts of the concrete, which affects the quality of the later project.

Description

technical field [0001] The invention relates to the technical field of concrete production, in particular to a method for preparing high-strength concrete by using waste fibers. Background technique [0002] Concrete refers to the collective name of engineering composite materials that use cementitious materials to cement aggregates into a whole. Usually, concrete refers to using cement as cementitious material, sand and stone as aggregates, and water can contain admixtures and admixtures. The mixture is mixed in a certain proportion, and the cement concrete obtained by mixing is also called ordinary concrete. It is widely used in civil engineering. Nowadays, waste broken fibers are usually added in the process of concrete mixing. The fibers mixed into the concrete slurry can be Improve the strength of concrete. [0003] The traditional mixing method usually directly mixes the concrete slurry with the fibers, but because the fibers are light and thin, putting a bunch of fib...

Problems solved by technology

[0004] In order to solve the above problems, the present invention provides a method of using waste fibers to prepare high-strength concrete, which can solve the problem of mixing concrete slurry with fibers directly in the traditional mixing method, but because the fibers are light and thin, a pile of fibers Putting it into the concrete slurry at the same time, it is often difficult to mix evenly in the later mixing process, and there are often cases where fibers are attached to the surface and shallow layers of the concrete slurry, but not mixed into the inner layer, resulting in different strengths of various parts of the concrete. Affected the later project quality and other issues
