Claims7
A top coating composition for a water retention structure comprising a hydraulic cement, an aggregate filler and a water insoluble fluorescent compound that is invisible to the human eye under normal lighting conditions but which will fluoresce or glow and be visible to the human eye when illuminated with an ultraviolet or infrared radiation source, the fluorescent compound being present in an amount of from about 0.0002 to about 0.7 weight percent of the cement, wherein the coating exhibits isolated specs when illuminated with ultraviolet or infrared radiation.
A top coating composition for a water retention structure consisting essentially of a hydraulic cement, an aggregate filler and a water insoluble fluorescent compound that is invisible to the human eye under normal lighting conditions but which will fluoresce or glow and be visible to the human eye when illuminated with an ultraviolet or infrared radiation source wherein said fluorescent compound is from about 0.0002 to about 0.7 weight percent of the cement.
A top coating composition for a water retention structure consisting essentially of a hydraulic cement, an aggregate filler, a water insoluble fluorescent compound that is invisible to the human eye under normal lighting conditions but which will fluoresce or glow and be visible to the human eye when illuminated with an ultraviolet or infrared radiation source, wherein said fluorescent compound is from about 0.0002 to about 0.7 weight percent of the cement, and a conventionally known additive taken from the group consisting of a liquefier, reinforcing fibers, a coalescence additive, a thixotropy control agent, a preservative, an antifoaming agent, a freeze thaw stabilizer, a setting accelerator, polymers, a coloring material and mixtures thereof.
