Provided herein are compositions, methods, and systems comprising vaterite and magnesium oxide.

Luminescent concrete compositions containing cement, fine aggregates such as sand, and a phosphor such as strontium aluminate. Glow-in-the-dark concrete products made therefrom and methods of producing such concrete products are also specified. The glow-in-the-dark concrete products demonstrate good mechanical strength (e.g. compressive strength) and skid resistance. The addition of phosphorescent strontium aluminate provides luminance that persists for up to 10 hours to the concrete products.

Various embodiments disclosed relate to a curable composition and resin for treatment of a subterranean formation. In various embodiments, the present invention provides a method of treating a subterranean formation. The method can include placing in a subterranean formation a curable composition. The curable composition can include an epoxy silane monomer, a hardener, and carrier fluid. The curable composition can include an epoxy monomer, an amine silane hardener, and carrier fluid. The method can also include curing the curable composition to form an epoxy silane resin.

High SRI cementitious systems comprising integral concrete coloring admixtures, toppings, dry-shake hardeners, and other cementitious systems are provided. The high-SRI cementitious systems comprise one or more IR reflective pigments and other components to make-up the cementitious system, depending on the application. The high-SRI cementitious systems of the invention may be in the form of mixtures which increase the total solar reflectivity (TSR or albedo) and the Solar Reflectance Index (SRI) of concrete. The high-SRI cementitious systems may be toppings mixed with water for application to existing concrete surfaces, dry-shake hardeners for application to freshly-placed plastic concrete, or the IR reflective pigments may be mixed into integrally colored concrete in various forms, such as conventional cast-in-place concrete, lightweight concrete, pervious concrete and concrete building panels, pavers or masonry units.

Disclosed are a cement coating for inducing the settlement of marine sessile organisms and an application technology therefor, and, in particular, a construction method for an ecological riprap breakwater, an induced cement-based coating, and a preparation method thereof. The cement coating for inducing the settlement of marine sessile organisms is coated on surfaces of rocks, and a reasonable spatial layout is applied, such that each rock pile (block) can effectively break waves and ensure smooth exchange between water bodies on two sides. After oysters attached to each rock pile (block) breed a large amount, the water bodies can be purified, and the ecological environment in the surrounding sea area can be improved.
