Study on the new phosphate cement repair material with super rapid hardening

Used as a kind of mending material,the modified cement concrete-polymer has wide applicability and economical value.

Influence of fly ash on property of phosphate cement based patching material;

To counter the problems occurred commonly in the base of asphalt pavement,a new self-compacting patching material consists of cement,aggregate and some additive such as water reducing and expanding additive named UEA is made up with the method of homogeneous design.

This paper analyses the technical schemes of corrosion patching, through practieal investigations and test researches on corrosion mechanism of hydraulic reinforced concrete structures, presents the optimum choise of patching materials.

Study and application of laser protective materials;

The technical specifications, types, performances and foreign application of laser protective materials are presented.

Author has introduced the corrosion causes of various kinds of gas tank,the concrete requirements of protective materials and protective construction design,discussion was made for protection construction procedures of various kinds of gas tank,the application practive indicates that the protection structure of coal gas tank,forming surficial/middle/bottom layers is the ideal protection design.

Aimed at the problem of traditional resist impact composites has only resist impact function,a multi-combination resisting impact protective material with the capacity of buffer shock be developed.
