Application and research of high performance polymer concrete in covers

The paper researches the applications of high performance polymer concrete which is used to make the manhole cover instead of iron´s. The covers has reached the China National Standards of CJ/T211-2005.Add toughening to epoxy resin concrete to modify to provide an initial experimental data and technical support in application of materials in the construction industry The manhole cover made by epoxy resin concrete modified, It takes the method of plastic analysis to research ultimate capability of manhole cover of high performance polymer concrete the manhole cover of epoxy resin concrete is very potential that it can come true the stronger capability, less cost and it don´t lost in use of the article´s results.
