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).

The described systems, methods, and compositions relate to systems, methods, and compositions for forming one or more cementitious materials that cure into one or more mortars or concretes. 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.

Embodiments of this disclosure provides systems and methods for displays. In embodiments, a display system includes a frame, an eyepiece coupled to the frame, and a first adhesive bond disposed between the frame and the eyepiece. The eyepiece can include a light input region and a light output region. The first adhesive bond can be disposed along a first portion of a perimeter of the eyepiece, where the first portion of the perimeter of the eyepiece borders the light input region such that the first adhesive bond is configured to maintain a position of the light input region relative to the frame.

Athermalization concepts for polymer eyepieces used in augmented reality or mixed reality devices

The described systems, methods, and compositions relate to systems, methods, and compositions for forming one or more cementitious materials that cure into one or more mortars and/or concretes. More particularly, some embodiments relate to systems, methods, and compositions for forming cured mortars and/or concretes that tend to have an increased strength over time due to the use of one or more reactive aggregates, activator materials, and/or alkaline compounds for conditioning the aggregate. In some cases, a cementitious mixture that is configured to form a mortar that can receive one or more filler aggregates (e.g., reactive filler aggregates) to make a concrete. Additionally, in some cases, the reactive aggregate is conditioned with an aqueous solution comprising one or more alkaline compounds having a concentration in the aqueous solution of between about 0.001 mol/L and about 10 mol/L, or within any subrange thereof (e.g., between about 0.25 molar and about 5 molar).
