(THE GIST OF PIB) Multi-Storeys Constructed with Thermocol could be the future Earthquake-resistant Buildings

Thermocol could be the material of the future for construction of earthquake-resistant buildings, with thermal insulation and could also save energy required to develop construction materials.

Researchers at IIT Roorkee have found that thermocol or Expanded Polystyrene (EPS) is used as a composite material in core of reinforced concrete sandwich, could resist earthquake forces on up to four-storey buildings.
They have attributed this earthquake resistance capability to the fact that the EPS layer is sandwiched between two layers of concrete having reinforcement in the form of welded wire mesh.
The researchers said that the force being applied on a building during an earthquake arises due to the inertia effect and hence depends on the mass of the building. Thermocol resists earthquakes by reducing the mass of the building.
In this technique, the EPS core and the wire mesh reinforcement is produced in a factory. The building skeleton is first erected from the factory-made core and reinforcement panels, and then concrete is sprayed on the skeleton core.
This technique does not require any shuttering and hence can be constructed very fast.
