A sheet 100 of water-soluble material such as polyvinyl alcohol comprises a plurality of individual, sealed pockets 110, each containing concrete admixture. The sheet is cut to size and attached to the interior of a formwork structure 200 with, for example, PVA glue. After concrete is poured into the formwork, covering the sheet 100, the sheet dissolves, releasing the admixture onto the surface of the concrete as it sets. In another arrangement, a sealed container 300 formed from a water-soluble material contains concrete admixture. The external wall of the container has a plurality of regions 320 where a thickness of the wall is reduced. The container is attached to interior walls of a formwork structure 200 or to reinforcing bars inside a formwork structure. After concrete is poured into the formwork, submerging the container, the container dissolves, with the thinner regions dissolving sooner, releasing the admixture into the concrete.

Soil remediation by molecular binding for producing beneficial use determined polymer concrete products
10676397 · 2020-06-09 ·

A method for soil remediation by molecular binding for producing beneficial use determined polymer concrete product that removes hazardous pollutants from a quantity of contaminated soil. Hazardous pollutants are identified though chemical analysis in order to select at least corresponding polymer and at least one corresponding binder for each hazardous pollutant present in the contaminated soil. The at least one polymer chemically bonds with the hazardous pollutant in order to neutralize the hazardous pollutant within the contaminated soil to form a polymer concrete product. The polymer concrete product is then used as a concrete substitute for construction applications.

Safety critical control system that includes control logic or machine readable instructions that selectively locks or enables the control system based on one or more machine implemented state machines that includes states associated with detection or matching of one or more predetermined signals on distinct conduction paths between elements of the control system and related methods

This disclosure involves a method of controlling a safety critical control device, the method comprising: sending user inputs to a first state machine, identifying user inputs by the first state machine, determining the correct state to communicate to a second state machine, the correct state being determined by selecting one state of a plurality of states depending on the user inputs, communicating the correct state to a second state machine through a control bus, and determining the correct state for the second state machine based on communication from the control bus.
