However, there are structures formed of glass tiles that provide a design feel that is quite different from the design feel provided by concrete.
Chinese patent publication No. 101906836B discloses a light-transmitting concrete member and a manufacturing process thereof. The technical key points of the product of the invention are as follows: the light-transmitting concrete member comprises a concrete main body, wherein a plurality of orderly arranged optical fibers are fixed in the concrete main body, and the optical fibers penetrate through the inner surface and the outer surface of the concrete main body. The invention maintains the original physical property and mechanical property of concrete, can meet the lighting requirement without holes, and has simple equipment and process and easy realization. The technical content described in the patent solves the technical problem of light transmission of concrete, but the light transmission direction is single, the light transmission direction is only unidirectional light transmission, the light transmission in multiple dimensions and directions cannot be formed, and the light utilization rate is further improved.
In addition, although the light-transmitting material based on the concrete can realize light-transmitting performance, the application range of the light-transmitting material based on the concrete is greatly limited due to the problems of the manufacturing process and the concrete material, and the light-transmitting material is concretely as follows:
1) Because the light-transmitting concrete adopts the plastic optical fiber, the surface of the plastic optical fiber is smooth, the adhesion degree with the concrete is weak, and the interface strength between the optical fiber and the concrete can be improved after the plastic optical fiber is subjected to surface treatment by using a coupling agent;
2) The water seepage problem exists in the concrete, and the surface must be subjected to water seepage prevention treatment;
3) The concrete needs to be maintained for at least more than one week from pouring to reaching the ideal strength to be demolded, and certain requirements are also met on maintenance conditions, so that the production period of the light-transmitting concrete is long, and the mass rapid production is difficult;
4) The concrete-based material is brittle although the strength is high, and is easy to crack when being cut or maintained improperly because the adhesiveness of cement is not high;
5) The concrete has coarse component particles, and cannot be subjected to precise secondary processing or surface treatment;
6) The concrete has poor dyeing property, and is difficult to process color or surface texture.
For example, in chinese patent publication nos. CN102166780a and CN103753690a, light-transmitting concrete is used, and the above-mentioned drawbacks are unavoidable.
The light-transmitting concrete has the limitation of use, and the patent of the invention comprises the light-transmitting concrete, the light-transmitting artificial stone and the light-transmitting wood, can provide light-transmitting materials with various materials, textures and colors, almost covers various applications of building landscapes, indoor decorations and furniture articles, and has very wide application fields.
