Systems and methods for self-sustaining saltwater reactive cementitious systems

Abstract

The described systems, methods, and compositions relate to systems, methods, and compositions for forming one or more cementitious mixtures that cure into one or more mortars and/or concretes. More particularly, some embodiments relate to systems, methods, and compositions for producing cementitious materials (or cured mortar and/or concrete compositions) that tend to increase in strength over time due to the use of saltwater (e.g., instead of freshwater) and/or due to the use of one or more reactive aggregates that interact with an activator material that is primarily comprised of lime. In some cases, the described cementitious material can (before being cured to form mortar or concrete) include one or more reactive aggregates; hydrating solutions comprising water with a salt content greater than 0.5 ppt; and/or activator materials comprising at least 40% calcium oxide by mass (e.g., when the activator is dry).
