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).

More particularly, some embodiments relate to systems, methods, and compositions for producing cured cementitious materials that tend to increase in strength over time due to the use of one or more reactive aggregates that interact with one or more activating materials (lime components). In some cases, a mortar or a concrete includes a reactive aggregate with an oven-dried bulk density between about 0.25 and 3.0 gm/cc and a porous structure, wherein at least 5% of a total mass of the reactive aggregate is comprised of particles less than (or equal to) 1 mm. In some such embodiments, the cementitious mixture further comprises a hydrating solution including water and an activating material, wherein the activator comprises at least 40% calcium oxide, by mass.

A method for preparation of 1 m.sup.3 of fresh concrete includes mixing 1000 to 2000 kg of aggregate in a forced circulation mixer, wherein 40% to 100% by weight of the aggregate is recyclate made from inert construction and demolition waste. Microsilica is added to the mixture under constant mixing, and the mixture is then mixed for 40 to 80 seconds, whereby the microsilica covers particles of the recyclate and fills up pores in the recyclate. Then under constant mixing, cement or cement and at least one substituent of cement is added to the mixture in a total amount of 135 to 600 kg, and the mixture is further mixed while sprinkling or spraying the mixture with 135 to 250 kg of mixing water for under constant mixing such that a surface of the cement is gradually wetted and a cementing compound being formed gradually adheres to the particles of the recyclate already coated with the microsilica. The mixture is continued to be mixed for 80 to 160 seconds, wherein fresh concrete is prepared.
