The light-transmitting concrete created by LiTraCon is created by embedding thousands of optical glass fibres into concrete. These fibres lie parallel to each other forming a pathway for light to travel from one side of the concrete block to the other. In theory, a wall might be several metres thick without any loss of light between surfaces. As the light reaches the other side of the block unchanged, sharp shadows can be seen through the wall.
The strength of the concrete is not affected by the glass fibres which make up only 4% of the content of the block and the concrete blocks can be used for both load-bearing and interior walls as well as pavements. If the walls are built facing east or west the light at sunset or sunrise will reach the glass fibres at a lower angle increasing the light intensity.
