Description

  The present invention relates to a method for manufacturing a light transmissive building material and a light transmissive building material.

Conventionally, a material such as concrete or cement is often used as a structural material for general construction. In recent years, the field of use of concrete or cement has expanded and may be used with additional design elements.
Here, the concrete or cement itself does not transmit light. Therefore, when it is desired to transmit light, for example, a method of forming a plurality of small holes in concrete or cement and transmitting the light from these holes is used.
On the other hand, a translucent material formed by mixing a translucent resin in the raw material mixing stage has also been proposed (see, for example, Patent Document 1).

JP-A-5-279509

By the way, when light is transmitted by forming a plurality of holes in concrete or cement, there is a problem that it is not suitable as a building material because wind, rain, sound, dust and the like other than light pass through these holes. It was.
Further, the translucent material described in Patent Document 1 has a problem that the strength of the translucent material itself is not high because the translucent resin itself is affected by the translucent resin.
