Problems solved by technology

[0004] 1) Shrinkage cracking is easy to occur: if the optical fibers are arranged in parallel and buried in the Portland cement concrete matrix, since the first generation of optical fibers uses glass as the core wire, it is easy to cause alkali- The silicate reaction should first affect the durability of the light-transmitting material;
[0005] 2) The stability of the optical fiber positioning is poor: due to the single use of steel rods or 3D and 2D textile technologies, the spacing of the optical fibers and the certainty of the symmetrical position cannot be guaranteed, resulting in poor stability of the optical fiber positioning;
[0006] 3) The stability of the light transmission is poor: if the positioning effect of the optical fiber is not satisfied, then the uniformity of the distribution of the fiber cloth fiber assembly in the cement slurry is not satisfied, so the light transmission performance of the material cannot be achieved. fulfil requirements;
[0007] 4) The construction process is complex: in the process of processing and forming, the stability of the optical fiber needs to be regulated, which increases the production process, and the production quality cannot meet the requirements.

Abstract

The invention discloses a method for preparing light transmitting concrete through application of optical fiber winding machine technology and belongs to the field of novel building materials. According to the method for preparing light transmitting concrete through application of optical fiber winding machine technology, organic material multimode optical fibers with the diameter from 0.5 mm to 1.5 mm are adopted, the optical fibers are wound to an optical fiber winding machine until an optical fiber integrated body with the preset width is formed to serve as a conductor for transmitting the optical fibers, and the specific effect of light transmitting and image transmission through cement concrete materials is achieved. The light transmitting concrete which is the novel fourth generation light transmitting concrete material has the advantages of being simple in technology and easy to operate, enabling light transmitting performance to be guaranteed and having good application prospect.

Description

technical field [0001] The invention belongs to the technical field of new concrete materials. Specifically, it relates to a preparation method of light-transmitting concrete with high light transmission, high strength, high stability, low cost, simple preparation process and industrialization. Compared with the third-generation light-transmitting cement-based materials, this cement-based material has the advantages of simple preparation process, stable optical fiber positioning effect and light transmission performance, and high strength. There are broad prospects. Background technique [0002] Although there have been related reports on cement-based light-transmitting concrete, there are few reports on the specific preparation process of cement-based light-transmitting materials. Arrange in parallel in the warp or weft direction, fix with cotton yarn, treat the surface of the optical fiber with a coupling agent, fix the fiber in the trial mold with a steel rod and a nail...
