Light Emitting Cement for Smart Construction

Can you ever imagine that your walls will illuminate the room without using any electric power? Have you ever thought that it’s easy to drive and walk on the roads in the middle of the night without any street lights? Well, it’s time to believe that construction technology has emerged in a way that you have never imagined. Innovation of light emitting cement is a new innovative and energy-efficient construction material which can produce light without any energy sources, save money and environment.

The cement can act as a light source for dark walkways without creating light pollution which disturbs wildlife and humans alike. Equally it is charged by natural light from the sun, just like solar powered lights you’d get in a garden.

How it is different form conventional cement?

The raw materials used for this material are silica, river sand, industrial waste, alkali and water. This process can be done at room temperature which includes the polycondensation of raw materials that doesn’t require much energy consumption. The chemical reaction between cement dust and water produces a strong and resistant mixture that looks like a gel along with some unwanted crystal flakes.

Cement is a binding material with excellent cohesive properties and possesses an opaque body which does not allow the passage of light penetrate inside the material.

Adding certain additives during manufacturing, scientists modified the optical properties of the material to make it phosphorescent. However, it is manufactured like ordinary cement, but the change in the microscopic structure creates a noncrystalline structure identical to the glass that allows passage of light inside.

This helps to save on electricity costs. It can be used to light up the footpaths, swimming pools, interior rooms, and roadways, etc.

Additives in this cement which make it phosphorescent material is absorb energy from the sun, in indoors from lights or lamps, and later they emit light in dark hours. As the material energises every  

It acts as a light source in the places where scarcity of power is there like roadways in the forest or in some remote areas where there is no availability of power. You can use this material in buildings, especially in bathrooms and garden paths.

It is currently available in two colours- blue and green, and the intensity of light can be adjusted during the making process.

Even it’s an eco-friendly also as the gel is made out of sand, dust, clay and water. The material has an estimated life span of 100 years because of the inorganic nature of the cement components. This new material is sun-resistant and more durable compared with other phosphorescent materials like plastics or paints, which decay with UV rays in the long run.

These types of innovations are turning up the trends in construction industry and technologies are evolving to the next level.
