As concrete innovation develops, it not only focuses on quality and cost but also the function of the concrete itself. One of the innovations is translucent concrete or LTC (light-transmitting concrete). Translucent concrete has unique mechanical properties and uses. Its ability to transmit light can reduce lighting energy requirements. There is research regarding low material strength and optimal fiber optic exposure ratio. This gap is reviewed through tests to investigate the effect of different ratios of optical fibers in making transparent concrete on material strength and light transmission properties for making green buildings. Transparent concrete is a type of concrete in the modern era that can transmit external light into buildings. Using fiber optics as a transparent material in concrete creates its light transmission effect. Transparent concrete can be used in architectural and construction applications and potentially reduce energy requirements for room lighting. In production, transparent concrete consists of a mixture of cement, fine aggregate, and fiber optics. The proportion and type of optical fiber used affects the level of light transmission.
Based on the compressive strength test results, transparent concrete with a 1:3 mixture of cement and sand and 3%, 4%, and 5% optical fiber have a compressive strength of more than K-100, so it is safe to use as a room wall, transparent concrete can be used as a green material. Building according to greenship summary standard v.10 GBCI and SNI 6197:2011 lighting system because it is capable of transmitting light, natural lighting analysis is flexible because it depends on the area of the walls and the area of the room.
