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.
Claims20
A concrete repair coating formulation, comprising:
- a cement component including a calcium sulfoaluminate cement and a Portland cement;
- and
- 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 wherein (a) said cement component has a ratio by weight of Portland cement to calcium sulfoaluminate cement ranging from 1/19 to 1/5.66 and (b) the coarse aggregates include screen fractions of (a) minus 500 microns by plus 250 microns of limestone, dolomitic limestone, dolomite or quartz sand constituting between 10-25% by weight of total product, (b) less than 250 microns by 125 microns constituting between 20-35% by weight of the total product and (c) less than 125 microns by plus 62.5 microns constituting between 6% to 10% by weight of total product.
A concrete repair coating formulation, comprising:
- a cement component consisting of 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;
