Method for preparing light-transmitting concrete

Abstract

The invention provides a method for preparing light-transmitting concrete. The method comprises the following steps of: 1) preparing an optical fiber bundle, an electrostatic emitter, optical fiber fixing grooves, cement, water, a setting accelerator and a template, wherein the optical fiber bundle is composed of a plurality of optical fibers; 2) weighing the cement, the water and the setting accelerator, mixing and stirring to prepare accelerated slurry; 3) releasing static charges to the optical fibers on the ends of the optical fiber bundle by using the electrostatic emitter; 4) respectively inserting two dispersed ends of the optical fiber bundle into the accelerated slurry in the two optical fiber fixing grooves, standing till the accelerated slurry is finally hardened, removing the hardened accelerated slurry from the optical fiber fixing grooves, and fixing the hardened accelerated slurry on the inner side of the template to be poured with concrete; and 5) pouring the concrete; removing the template after the concrete is hardened; and polishing the concrete till the end surfaces of the optical fibers are exposed out of the concrete structure, thereby obtaining the light-transmitting concrete. The method provided by the invention realizes the fast dispersion and fixation of optical fiber ends, and can be applied to the production of prefabricated light-transmitting concrete components and the construction of a cast-in-place light-transmitting concrete part.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a preparation method of light-transmitting concrete. Background technique [0002] The reason why light-transmitting concrete can transmit light is that the optical fibers between the two planes of the concrete are placed in parallel in a matrix, and the light passes through the optical fibers from one side of the concrete to the other in a point-like manner. Light-transmitting concrete can be used to make garden architectural products, decorative plates, decorative blocks and curved surfaces, which provides the possibility of realizing the artistic imagination and creation of architects. [0003] In 2001, the Hungarian architect Aron Losonczi first proposed the concept of light-transmitting concrete, and successfully developed light-transmitting concrete (LiTraCon) in 2003 using light glass fibers. However, the interior of the concrete is a highly alkaline...

Problems solved by technology

[0003] In 2001, the Hungarian architect Aron Losonczi first proposed the concept of light-transmitting concrete, and successfully developed light-transmitting concrete (LiTraCon) in 2003 using light glass fibers. However, the interior of the concrete is a highly alkaline environment, and light glass fibers are in Erosion is prone to occur in this environment, which affects the long-term light conductivity of light-transmitting concrete

Chinese patent 200710007521.X provides a light-transmitting concrete production module and its rapid production method, which can directly form light-transmitting concrete of different sizes according to different design requirements. When light concrete is used, the number of light transmission units will be large, and the workload of regularly fixing a large number of light transmission units between the top form and multiple bottom forms is large and the operation is slow

Chinese patent 201210070586.X provides a method for preparing light-transmitting concrete blocks and its preparation device. This method can conveniently, quickly and continuously prepare light-transmitting concrete blocks. However, this method still needs to penetrate optical fibers into each In the holes of the clapboard, this process is slow and requires a lot of work

Chinese patent 201210070575.1 provides a construction method for on-site pouring of light-transmitting concrete. This method has the characteristics of convenient implementation and promotion, designable concrete light-transmitting effect, low production cost, and is suitable for on-site pouring. The root penetrates into the hole of the optical fiber fixing plate, the operation is also slow and the workload is heavy

[0005] In summary, the preparation methods of the above-mentioned light-transmitting concrete all have problems such as slow operation of arranging optical fibers, heavy workload, and low efficiency.
