CSIR’s Transmission Tower for Bangladesh Success Laced Composite System
A (G+1) Prefabricated Building Assembled on Shake Table for Seismic Test
Construction using EPS panels for Kendriya Vidyalaya in CSIR-CLRI campus
Mass Housing using EPS panels in Srikakulam, Andhra Pradesh for ‘Hudhud’ cyclone victims
Indian Patent filed– Patent Application No.: 2441 DEL 2013, Date: 19/08/2013
Level / Scale of Development
Lightweight large wall and roof panel has been developed at CSIR-SERC. The flexural and axial behaviour of these panels have been evaluated. A proto-type G+1 storey has been constructed and studied for seismic behaviour on shake table and also by pushover analysis. Experimental demonstration of construction of four classrooms for Kendriya Vidyalaya, CLRI, has been completed using the lightweight large wall panels.
Application / Uses
- For mass and affordable housing
- For quality and speedy construction
- Constructions in earthquake prone areas
- Lightweight buildings in poor soil conditions
- For all types of single and multi-storeyed buildings
Salient Technical Features including Competing Features
- The panels are sandwich type comprising of two high strength concrete wythes separated by an inner lightweight core
- The consumption of concrete is low and most structurally efficient, due to the use of light weight inner core material
- Extremely light in weight and easy to handle, transport and erect.
- Can be assembled on the site edge to edge to form an enclosure and the joints between the wall to wall and roof to wall is connected through connectors.
- Provides satisfactory thermal and acoustic insulation for the constructed facility.
- The use of waste material in large quantities is also involved which adds to eco-friendliness of the system, besides structural soundness
- A (G+1) building constructed using light weight panels tested for seismic loading effect and loadings of seismic zone-5 was applied and the building performed excellently
- The entire system is light in weight, durable, and resistant to forces caused by disaster such as earthquake.
Major Raw Materials to be Utilized
EPS panels, rebars, cement, Fly ash, sand, coarse aggregate, carboxylated ether, viscosity modifying agent and water
Major Plant Equipment and Machinery Required
Concrete mixer machine
Affordable Construction Materials for seismic resistant Structure
Consists of procedure and methodology for preparation of light weight wall and roof panels, connection and joints details for assembly
