Concrete Repair

[shin25]

Currently I have been prescribing concrete repair procedure for some bridge components. These repairs are for general production defects like large honey comb, spalling, etc. The product that I prescribe to do the repair with is EMACO S88 C1 for non structural conditions. Also, this product is approved by the owner.

These bridge components will be erected in one of the north eastern states in USA, where temperature fluctuation is significant.

I am concerened that in the long run the repair material (EMACO S88) may delaminate. Because, concrete and this product may not have same coeff. of thermal expansion.

What do you all think?

Contact the manufacturer, I am sure they would have done some research with regards to this.

Have you required surface preparation equal or above what is recommended by the manufacturer and ensured the contractor is aware of the expectations and requirements? The surface preparation is generally key to a lasting concrete patch.
