The present invention is directed to a gypsum panel with reduced water usage and a method of making such gypsum panel. For instance, in one aspect, the gypsum panel comprises a gypsum core and a first facing material and a second facing material sandwiching the gypsum core, wherein the gypsum core includes gypsum and a water reduction agent. The methods of the present invention are directed to making the aforementioned gypsum panels. For instance, a method may include providing the first facing material, providing a gypsum slurry comprising gypsum, water, and a water reduction agent onto the first facing material, and providing a second facing material on the gypsum slurry.

This disclosure is directed to an improved ballistic concrete barrier for stopping projectiles with a kinetic energy of between about 1.0 kJ (750 foot-pounds) and 20.3 kJ (15,000 foot-pounds) in between about 3 inches and 10 inches. In one embodiment, the ballistic concrete barrier comprises (a) about 1 part by mass Portland cement; (b) about 0.5 to 1.5 part by mass fine aggregate; (c) about 0.005 to 0.15 part by mass fiber; (d) about 0.005 to 0.05 part by mass calcium phosphate; (e) about 0.005 to 0.05 part by mass aluminum hydroxide; and (f) about 0.0005 to 0.05 part by mass air entrainment additive, such that the ballistic concrete barrier is capable of stopping a fifty caliber bullet in less than 10 inches from a point of entry into the barrier.

An asphalt modifier includes bitumen, polyolefin particles, and one or more alkyl terephthalamides. Preparing an asphalt modifier includes combining one or more alkyl terephthalamides, polyolefin particles, and bitumen, and dispersing the polyolefin particles in the bitumen to yield the asphalt modifier. Digesting polyethylene terephthalate includes combining polyethylene terephthalate with an alkylamine or carboxyalkylamine to yield a reaction mixture, and heating the reaction mixture to a temperature between about 20 C. and about 300 C. to yield an alkyl terephthalamide.
