Abstract: A method for repairing defects on a structure is disclosed herein. The method comprises use of an additive manufacturing head to inject a flowable filler material into the defect. In certain embodiments, the additive manufacturing head can be a laser metal deposition (LMD) head comprising a powder nozzle and a laser. The structure can be, e.g., a pipeline or a pressure vessel used in petroleum, petrochemical, or natural gas applications.

Abstract: Provided are cementitious mixtures and processes for reinforcing a cementitious matrix. In one form of the process for reinforcing a cementitious matrix includes the steps of mixing a mineral cement and one or more populations of synthetic copolymer microfibers including about 1 mol. % to about 25 mol. % and from about 75 mol. % to about 99.5 mol. % of propylene monomeric units.
