Message:
How can we make concrete resistant to very high temperatures (hundreds of degrees) ? Can addition of nano particles help in this case?

Certainly you could use high aluminous cement concrete with a variety of different aggregate types. With respect to increasing the working temperatures and extending the service life of portland cement concrete, there has been some work published on the positive results of vacumn dewatering the freshly placed concrete. I would suspect that the addition of nano particles would also help in this case, but have no specific knowledge of their application here.

sir,

can the use of thermal barrier coatings(yttria-stabilized zirconia ) on aggregates be useful to make the concrete resistant to high temperatures? Can these coatings bond with cement properly?
