Ferrocement/Ferroconcrete has been recognised as a Separate Construction Technology by the American Science Congress in 1972. It is on the approved technology list of HUDCO, BMTPC, CBRI, PCERF, Concrete Institute of India, IE(I) etc.

EXTENSIVE WORKS DONE IN INDIA FOR: RDSO & Indian Railways UPSRTC UP Jal Nigam UK Forest Department UK Organic board UK Dairy Development Board Dehradun Municipal Corporation Gas Authority of India Ltd. (GAIL) Maharashtra Water Works

Tanjun Associate LLP has been organizing this event with the Institution of Engineers ( India), and eminent researchers, academicians, engineers & architects across India since the year 2012.

Ferroconcrete has been used extensively in housing, roofing, water tanks and storage construction for over 65 years globally. What is ferro-concrete ?

!! Dense concrete impregnated wire-mesh structure

!! Very high strength & very low weight (in some cases over 8 times stronger than RCC)

!! Strength through shape and

NOT by mass

!! Highly water and earthquake resistant

!! Affordable, Quick and extremely durable (Life-span is same as RCC)

Ferroconcrete was certified in 1991 by IIT Kanpur as one of the most suitable and durable materials of our times. IIT-KANPUR certification

August 10, 1991 Mr. Ashok Jain Director M/s Ashok & Associates Lucknow Dear Ashok, Subject: Ferrocement Prefabricated Housing Panels

I am glad to inform you that the prefab panel 2850x900x150 has been tested under all possible loadings expected on the element for its use as wall, roof and floor. The element is safe for a live load of 4.5 kpa (450 kg/m2 approx) when used as a roof panel; a wind load of 6.0 kpa (600 kg/m2 approx) for a wall panel.

The structure made of the panels as per Chunar Project will

be in a position to withstand the codal forces (live, wind, seismic etc.) safely. As the margin is more than 100%, economy may further be done. The structure can withstand an earthquake of intensity 9.0 on the Richter scale. This is the speciality of this type of element assembly. The number of bolts may be altered for different situations.

Besides, the structure is blast proof. Only mortar falls off

which in turn can be repaired easily, insitu. I would like to add that custom made panels can be designed

for different levels of loads/thermal/acoustic comfort using the filler materials.

If you have any queries, please call me.

Yours Sincerely,

(ASR Sai)

LIVE LOAD (450kg/m2) & WIND LOAD (650kg/m2)
