A more stable polymorph of water than common ice (Ice I h), which instead of melting when above 0°C (32°F), only melts at 45.8°C (114.4°F). When ice-nine comes in contact with liquid water below 45.8°C, it acts as a seed crystal, and causes the solidification of the entire body of water, which quickly crystallizes as more ice-nine ...
Water–cement ratio. The water–cement ratio ( w/c ratio, or water-to-cement ratio, sometimes also called the Water-Cement Factor, f) is the ratio of the mass of water ( w) to the mass of cement ( c) used in a concrete mix: The typical values of this ratio f = w⁄c are generally comprised in the interval 0.40 and 0.60.
Gypsum concrete. Phosphorgypsum-based concrete with sawdust aggregate. Gypsum concrete is a building material used as a floor underlayment used in wood-frame and concrete construction for fire ratings, sound reduction, radiant heating, and floor leveling. [1] It is a mixture of gypsum plaster, Portland cement, and sand.

Roman concrete, like any concrete, consists of an aggregate and hydraulic mortar, a binder mixed with water that hardens over time. The composition of the aggregate varied, and included pieces of rock, ceramic tile, lime clasts, and brick rubble from the remains of previously demolished buildings. In Rome, readily available tuff was often used ...
Cement shoes, concrete shoes, or Chicago overcoat [1] is a method of murder or body disposal, usually associated with criminals such as the Mafia or gangs. It involves weighing down the victim, who may be dead or alive, with concrete and throwing them into water in the hope the body will never be found.
The idea is that the steam displaces the air normally over the concrete. When the steam condenses into water it will create a low pressure over the concrete that will pull air from the concrete. This will make the concrete stronger due to there being less air in the mixture. A drawback is that the mixing has to be done in an airtight container.
