Abstract

The invention discloses a method for preparing a cement-based light transparent material by applying an optical fiber parallel arrangement process, belonging to the field of novel building materials. The cement-based material comprises cement mortar, cement concrete and the like which are dense and light-proof. In the method, vitric multimode fibre is firstly selected, a coating is coated on the surface of the multimode fibre, and a coupling agent is selected for preprocessing the surface of the multimode fibre. The diameter of the multimode fibre is 2-300mum, a large quantity of multimode fibre beams are embedded in the cement-based material in a parallel arrangement mode, the direction of the multimode fibre beams is consistent with the light transmittance direction, and the multimode fibre beams are used as conductors for transmitting light for realizing special effects of transparency image transmission and the like of the cement concrete, and the volume fraction of the multimode fibre in a building block is 5-30 percent. The cement-based light transparent has better light transparency performance and a variable decoration effect, is one revolution of the cognition and the concept of the cement concrete, and has a wide application prospect in the fields of building illumination energy saving and building decoration.

Description

technical field [0001] The invention belongs to the technical field of new concrete materials. In particular, it relates to a preparation method of a cement-based light-transmitting material. Background technique [0002] Compared with traditional light-transmitting materials—glass and plexiglass, cement-based light-transmitting materials are a new kind of light-transmitting materials, which are completely different in terms of material composition, light-transmitting principles, and material properties. Its basic composition is that a large number of optical fibers are embedded in a cement-based material matrix in a certain spatial arrangement and combination. The cement-based material used as the matrix should be fine aggregate, high-fluidity cement slurry or concrete. The principle of light transmission is different from the light transmission of the matrix of glass or plexiglass material, but relies on a large number of optical fibers to transmit light between the side ...
