Abstract
A concrete and asphalt repair coating formulation includes a cement component and an aggregate component. The cement component includes a calcium sulfoaluminate cement and a Portland cement. The aggregate component includes coarse aggregates between 125-500 microns in diameter and fine aggregates between 5-62.5 microns in diameter.
Claims22
A concrete repair coating formulation, comprising:
- a cement component including a calcium sulfoaluminate cement and a Portland cement;

- an aggregate component including coarse aggregates between 62.5 microns and 500 microns in diameter and fine aggregates between 62.5 microns to less than 5 microns in diameter.
A concrete repair coating formulation, comprising:
- a cement component including a calcium sulfoaluminate cement and a Portland cement having a ratio by weight of Portland cement to calcium sulfoaluminate cement ranging from 1/19 to 1/5.66;
- an aggregate component with gradation spanning from 500 microns to less than 5 microns;
- a set time retarder;
- a water reducing agent;
- and a defoaming agent.
