Method for preparing high-strength concrete from waste fibers

Abstract

The invention provides a method for preparing high-strength concrete from waste fibers, which is implemented by matching a bottom frame, a connecting frame, a stirring device, an electric turntable, arotating frame, a stirring paddle, a sealing cover and a blowing-away device, and can solve the problems that in the traditional stirring mode, concrete slurry and fibers are generally directly mixedand directly stirred; however, due to the fact that fibers are light and thin, a pile of fibers are put into concrete slurry at the same time, even mixing is difficult in the later stirring process,the situation that the fibers are attached to the surface layer and the shallow layer of the concrete slurry and are not mixed into the inner layer often exists, the strength of all parts of the concrete is different, and the later engineering quality is affected.

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.
