3-Fluoro-5-trifluoromethoxybenzaldehyde is a retardant that can be used to prevent the premature setting of concrete. It works by reacting with the calcium hydroxide in cement and forming calcium fluoride, which does not react with water. This reaction system is reversible and can be reversed by adding water. The structural formula for 3-fluoro-5-trifluoromethoxybenzaldehyde is CHClFO, and its structural formula is shown below:
Some common retardants are 3,4,5-trihydroxybenzoic acid (PHBA), methyl ethyl ketone peroxide (MEKP), and sodium benzoate. These substances work by breaking down into reactive radicals when exposed to ultraviolet light or heat. These radicals then react with the calcium hydroxide in cement to form calcium salts such as calcium fluoride or calcium carbonate, which do not react with water.
