A team of scientists has created a new light-emitting cement which is capable of illuminating roads, highways and bicycle lanes during the night time. Scientists say the new light-emitting cement can last for a hundred years. It absorbs solar energy during the day and hence emits light at night. The cement currently exists in blue or green colour only. The intensity of light can also be regulated in order to avoid dazzling drivers.
“The main issue was that cement is an opaque body that doesn’t allow the pass of light to its interior,” said Jose Carlos Rubio, from Michoacan’s University of San Nicolas Hidalgo (UMSNH) in Mexico. Common cement is a dust that when added to water dissolves like an effervescent pill, Rubio explained.
