A manufacturing method, comprising:
- incorporating at least one calcium-containing additive into a concrete mixture including aggregates prone to alkali-silica reaction;
- and
- curing the concrete mixture to form a concrete product.
A manufacturing method, comprising:
- incorporating at least one divalent cation-containing additive into a concrete mixture including aggregates prone to alkali-silica reaction;
- and
- curing the concrete mixture to form a concrete product.
A concrete product, comprising:
- a binder;
- aggregates dispersed within the binder;
- and
- a calcium-containing interfacial layer at least partially covering the aggregates.
