High Modulus Repair Material

[khinz]

For structural repair such as foundation, beams, columns where part of the concrete have to be replaced and it has to share the compression and tensile load. What repair material with modulus of elasticity close to concrete that you normally use? How about non-shrink grout, what is its modulus compared to concrete? I just want to know.

Suggest you contact Sika.

Agree with hokie66. Sika has good products (you will be looking for a repair mortar or similar pre-mixed material). If by chance you can find one of the older Sika Concrete repair manuals, it has excellent information and procedures on such repairs. I know they do not produce those in the US anymore, but might be available elsewhere.

I need papers to what extend you can replace concrete with these high modulus non-shrink grout. For example, underneath the midspan of a beam that is in compression.. what is the rule of replacing a part of it with these compatible material supposed there is sufficient shores that support all part of the beam and the load.. i mean rule like can one just replace a part of the concrete of the beam (one half of the lower part) or the rule needs the whole section? Well. Believe it or not. If you would ask these to structural engineers. They don't necessarily know as it is specialized knowledge. So in addition to asking them. I need information or references about this so I know it is standard of other experts agree on it. Again. I want just to see opinions of experts IN ADDITION to local structural engineers for reference to know what is standard or allowed practice. I'm not doing or planning any myself. Just need to know them because I'm a contractor/civil engineer.

i mean above the beam in compression as I know the bottom is in tension that is why there are rebars, it's just an example.
