Abstract
A cementitious composition of one embodiment, according to the present teaching, includes, but is not limited to, a Portland cement, and at least one other cement from a group comprising, but not limited to, calcium sulfoaluminate cement, a calcium aluminosilicate cement, and calcium aluminate, wherein the Portland cement has a content of at least 20 percent based on the total weight of the non-Portland hydratable cement powder, wherein the cementitious composition bonds to asphalt.
Claims27
A cementitious composition comprising:
- a Portland cement;
- and at least one other cement from a group comprising calcium sulfoaluminate cement, a calcium aluminosilicate cement, and calcium aluminate cement;
- wherein the Portland cement has a content of at least 10 percent based on the total weight of the non-Portland hydratable cement powder;
- wherein the cementitious composition is used for bonds to asphalt.
