I am researching the use and specification of polyurethane grouts for corrosion protection and rehabilitation of post-tensioned cables in bridge beams, as well as stay cables. I have the following questions:
I am aware of electrochemical (rusting), stress-corrosion cracking and hydrogen...
I am looking for a standard, guideline or specification that delineates the definition of HI-MODULUS versus LOW-MODULUS epoxies and polymers (tension and compression).
In other words, are there limitations for these properties, in terms of actual numbers, for a material to be defined as either...
I am looking for information, case studies, papers, design examples, etc. for the use of chemical grouting to enhance the capacity of helical piers.
Questions I have:
Has the been any case study developments in this application?
What are the parameters for the size of the grout ball...
I am looking for a standard or specification that delineates the definition of HI-MODULUS versus LOW-MODULUS epoxies and polymers. I.e., what is the limitations for each to be defined as either a HI-MOD or a LOW-MOD product?
