Abstract

The invention discloses a high-performance light-transmitting concrete slab and a preparation process thereof. The high-performance light-transmitting concrete slab comprises a concrete base body and light-transmitting fibers arranged in the concrete base body. The concrete matrix is prepared from the following raw material components in parts by weight: 15-20 parts of Portland cement, 10-18 parts of slag powder, 12-20 parts of fly ash, 3-6 parts of silica fume, 26-33 parts of quartz powder, 8-10 parts of water and 2-4 parts of alkali activation agent; the light-transmitting fibers are soaked in a silane coupling agent solution. According to the high-performance light-transmitting concrete slab, the strength of the concrete slab is effectively improved while the light-transmitting performance and the decorative performance are guaranteed, the high-performance light-transmitting concrete slab has practicability and decorative performance, and the problems that an existing light-transmitting concrete slab is poor in strength and performance is reduced are solved. The preparation process of the high-performance light-transmitting concrete slab is simple, and the prepared high-performance light-transmitting concrete plate is high in strength and good in decorative effect.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a high-performance light-transmitting concrete slab and a preparation process thereof. Background technique [0002] Concrete is the most commonly used building material in modern architecture. With the development of the times, the construction industry has higher and higher requirements for concrete, and concrete has a new development direction. High-performance concrete has excellent properties such as high strength and high durability, but lacks certain decorative properties. Light-transmitting concrete has good decorative properties and can transmit light. The combination is low. Adding light-transmitting fibers to concrete seriously affects the strength of concrete products, resulting in lower performance than ordinary concrete products. The pre-mixed concrete is grouted into a mold with light-transmitting fibers for maintenance. After forming, concrete products...
