Abstract: A lightweight structural concrete formulation comprises a wet mix of about 460 kg/m3 of cementitious material such as ordinary Portland cement of which about 50 percent has been replaced by ground granulated basic furnace slag (GGBFS) and 7 percent by silica fume (SF) in other words the mix introduces between about 178 and 228 kg/m3 therefore the combination is good to produce secondary reaction products when the cement hydrates which produces secondary calcium silicate hydrate (C—S—H) which makes the structure dense and thereby increases its mechanical durability characteristics of the concrete product. Possible ratios of GGBFS and SF are 30-70 percent and 5-10 percent, respectively. By making the structures dense increases the mechanical and durability characteristics of the concrete product. Other ratios have been made including GGBFS of 30-70 percent and silica fume 5-10 percent, respectively.

Abstract: A system is provided for generating an alert to the presence of emission vapors for a low altitude in-flight aircraft. An obstacle database and a terrain database provide parameters for obstacles and terrain features to a synthetic vision processor. The processor creates a graphic overlay of the terrain and obstacles that is combined with thermal images of emission vapors by a combined vision processor to create a combined synthetic image. An emissions threat calculator analyzes the synthetic image for the presence of emission vapors. If any emission vapors are detected in proximity to the aircraft, an alert and suggested maneuvers to avoid the emission vapors are sent to the aircraft.
