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.

A process for immobilizing hazardous waste includes mixing the hazardous waste with a non-swelling clay, a cementitious binder and, optionally, water, and allowing the resulting mixture to set to an immobilized waste material. The process can also include dispersing the hazardous waste in the non-swelling clay to form a dry mixture, mixing the cementitious binder and, optionally, water with the dry mixture to produce a plastic mixture, and allowing the plastic mixture to set to the immobilized waste material.

A retrofitting appliqu for stepped application to a building wall construction. For external retrofitting, the system has an air barrier layer impermeable or semi-permeable for moisture, a ventilated air cavity used to modify temperature and/or remove water that may be coming from both sides or to modify the relative humidity of the ventilation air, a layer of thermal insulation, a composite material called Eco-Wrap with capillary active capability, in which a hydronic heating or cooling system may be located, and a surface finishing layer. For internal retrofitting, the system has an air barrier system arranged onto the wall of the building and separated from a layer of permeable or semi-permeable thermal insulation by a ventilated air gap. The layer of insulation, in turn, is in contact with a layer of Eco-Wrap. A permeable interior finishing layer that may also have capillary active performance is in contact with the Eco-Wrap. Methods for installing the retrofitting appliqu are also disclosed.

The present concrete composition uses Asian carp fishmeal (the burned remains of the carp) as an admixture. The core principle behind the development of present concrete composition stems from attempting to find a beneficial use for a waste product in a civil engineering application. The incorporation of the fishmeal improves the cementitious properties when added to a concrete mix. Thus, the fishmeal concrete composition incentivizes the harvesting of Asian carp and the production of fishmeal.

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.
