Engineered Cement Composites : Bendable concrete

May 5th, 2005 | Filed under: Architecture, Building Tech, Fabrication Tech, Materials, News, Products | 47 Comments »

Victor Li, at the University of Michigan has developed a new fiber-reinforced bendable concrete. Li claims his Engineered Cement Composites (pdf) are superior to other fiber-reinforced concretes because his composite not only uses microscale fiber reinforcements, but they have also designed the ingredients to the concrete itself to provide more flexibility. The 40% lighter ECC is also 500 times more resistant to cracking, 37% less expensive, consumes 40% less energy, and produces 39% less carbon dioxide than regular concrete.

    In the present situation of the earth,where it is underging serious changes,there is a need to replace the conventional materials.therefore the bending concrete is really the one needed. The picture given is a impressive one and has made me to think about the materials used for its preparation. kindly publish the materials and proportions clearly.

    To: Victor Li


    CONGRATULATIONS on your outstanding achievement! THANK YOU for your dilligence and your hard work.

    Is this a patented or proprietarty improvement?
    Would it be possible for a builder (me) in the field to
    make a material that would be as flexible as shown in this web page?
    It looks (the photo) similar to a page in the website.The Grancrete is designed to be applied (sprayed or troweled) to expanded polystyrene (beadboard) panels. Is your material capable of the same application; can your material be applied as a ‘stucco’ coating directly to polystyrene beadboard in the same way?
    Would you be able to forward to me a list of the materials and proportions that I might experiment a bit with your material?

    Thank you in advance for your reply

    Dear sir,

    It is very impressive and I would like to know about this in detail. especially, I am wondering that this material is applicable to steel sandwich plate system. (steel-concrete-steel)
    In this case, Debonding strengh is our concern. I would like to hear your opinion regarding debonding strength and after discussion I think we can make Joint development group for steel sandwich plate system
    I will wait your reply..
    thank you
