Abstract
A process for forming an inlay in a cured concrete structure includes forming a pocket in a preexisting concrete structure, filling the pocket with a cementitious mixture, curing the mixture in the pocket to form a cured mixture, and polishing the cured mixture in the pocket. The cementitious mixture includes a Portland cement, an admixture comprising at least one of a strengthener, a plasticizer, or an accelerator, and an aggregate.
Claims20
A process for forming an inlay in a cured concrete structure, the process comprising:
- forming a pocket in a preexisting concrete structure;
- filling the pocket with a mixture, wherein filling the pocket with the mixture comprises filling the pocket with the mixture to a height at least about one half of an average diameter of the aggregate above a surface of the preexisting concrete structure, and wherein the mixture comprises:
- a Portland cement comprising two or more oxides of silicon, iron, aluminum, calcium, magnesium, sulfur, potassium, and sodium;
- an admixture comprising at least one of a strengthener;
- a plasticizer, or an accelerator;
- and
- an aggregate;
- and
- curing the mixture in the pocket to form a cured mixture;
- and
- polishing the cured mixture in the pocket approximately level with the surface of the preexisting concrete structure.
A composite having an inlay in a preexisting concrete structure, comprising:
- a pocket formed in the preexisting concrete structure;
- a cured mixture disposed in the pocket and bonded to the preexisting concrete structure, wherein the cured mixture is polished level with a surface of the concrete surrounding the pocket, and wherein the cured mixture comprises:
- a cementitious mixture, comprising:
- a Portland cement comprising two or more oxides of silicon, iron, aluminum, calcium, magnesium, sulfur, potassium, and sodium;
- an aqueous fluid;
- and
- at least one admixture comprising:
- a strengthener,
- a plasticizer, and
- an accelerator;
- and
- an aggregate.
A composite having an inlay in a preexisting concrete structure, comprising:
- a pocket formed in the preexisting cured concrete structure;
- a cured mixture disposed in the pocket and bonded to the preexisting concrete structure, wherein the cured mixture and the preexisting cured concrete structure are both polished level, and wherein the cured mixture comprises:
- a cementitious mixture, comprising:
- a Portland cement comprising two or more oxides of silicon, iron, aluminum, calcium, magnesium, sulfur, potassium, and sodium;
- an aqueous fluid;
- and
- at least one admixture comprising:
- a strengthener,
- a plasticizer, and
- an accelerator;
- and
- an aggregate, wherein the aggregate comprises between about 60% to about 80% by volume of the cementitious mixture.
