This study aimed to investigate the potential of Light-transmitting concrete (LTC) in transmitting natural light or sunlight, and explored the relationship between fibre diameter, fibre spacing, solar incidence angle, surface area, and light transmittance properties. The study developed an artificial neural network model and explicit equations to predict the light transmittance of LTC, and found that the incidence angle and surface area had significant effects on light transmittance. Additionally, the effect of these factors was reduced with smaller fibre diameter or larger fibre spacing. The ANN model and equations showed good accuracy in predicting LTC's light transmittance.
This study aims to reveal the potential of Light-transmitting concrete (LTC) in transmitting natural light or sunlight, and to investigate the relationship between fibre diameter, fibre spacing, solar incidence angle, surface area, and light transmittance properties. The artificial neural network model as well as explicit equations from the model were developed to predict the light transmittance of LTC. The surface area was altered by varying LTC block arrangements from one to six. It was found that light incidence angle significantly affected the light transmittance of LTC. The highest light transmittance of LTC was achieved near solar noon, but it decreased drastically as soon as the solar incidence angle exceeded the acceptance angle. The effect of the LTC surface area and solar incidence angle on light transmittance diminished with a smaller fibre diameter or larger fibre spacing. The ANN model and explicit equations developed from the network provide good accuracy in predicting light transmittance of LTC.
