- n. The qualities necessary for making hydraulic cement, or that kind of mortar which will harden under water; the property of setting under water.
Sorry, no etymologies found.
There are some possibilities of additives to improve the basic qualities of lime: pozzolanic materials (rice husk ash, fly ash powdered brick, etc) to give a degree of hydraulicity, marble dust to increase hardness, and oil to quicklime to give a waterproof composite.
In the Wm. Millar and Christian Fair Nichols patent for "Improvements in the means of accelerating the setting and hardening of cements," they take advantage of the hydraulicity of certain of the salts of magnesia, by which the cements set hard and quickly while wet.
Hydroelectric production, equal to 1,640 GWh -12%, was affected by the lower hydraulicity recorded by the plants in Calabria.
Decreased profitability in the electricity sector can largely be attributed to the lower hydraulicity of the hydroelectric plant in Calabria, the lack of the essential requirements previuosly recognized in the thermoelectric plant in Monfalcone (carbon and fuel oil), as well as the deconsolidation of the economic results in terms of the gross operating margin of the San Filippo del Mela plant in Sicily (fuel oil) which exited the perimeter regulated by Tolling Agreement contracts with Edipower.
