The invention relates to a product and method for repair of roadway or pavement damage such as potholes, concrete/asphalt joints, and other damage to paved surfaces. The product can be adjusted in terms of the cure time of the product, allowing the user to customize the product for best use in the particular repair being made. Fast cures can be obtained of 5 minutes or less, suitable for quick repair of a small defect in pavement, or the cure time can be extended to 60 or more minutes, suitable for larger projects that can take many hours to complete. The product, when mixed, handles like easily pourable concrete mix, but acts like a hot mix repair when cured.

A concrete formulation system for repairing a cultural relic building and a use method thereof. The method includes obtaining a first index value, a second index value, and a third index value of a cultural relic building concrete sample and comparing the index values in a database of the concrete formulation system to obtain raw material components and contents of an original preparation formula of cultural relic concrete. The method further includes preparing a repairing concrete sample, measuring the index values, of the repairing concrete sample and comparing the index values of the cultural relic building concrete sample, and if the result is that the difference between the first index values is not greater than 20%, the difference between the second index values is not greater than 60%, and the difference between the third index values is not greater than 60%, using the repairing concrete sample for cultural relic repair.

A system for forming a coating on a substrate is provided. The system includes a first mix having a cement, a filler, a defoamer, a cement retarder, a dispersing agent, or any combination thereof. The system additionally includes a second mix having a fatty acid derivative, a synthetic resin, one or more organosilicon compounds, a pigment, a thickener, or any combination thereof. A coating composition is formed by mixing the first and second mix together. Lastly, the system includes a spraying apparatus that applies a wet film to the substrate wherein the cured coating does not yield to wet-rubs and does not stain (effloresce) with cold distilled water.
