Calcium chloride (CaCl2) has the ability to accelerate cement hydration and reduce set time by as much as two thirds. Research has shown that a 2% addition rate has an equivalent cure strength at 50°F as plain concrete at 70°F. Set times below 50°F will be longer, but the accelerated cure rate will still be greater than that of plain concrete.

COPPER CHLORIDE page 2 of 6 This Fact Sheet is a summary source of information of all potential and most severe health hazards that may result from exposure. Duration of exposure, concentration of the substance and other factors will affect your susceptibility to any of the
Durability and service life of concrete structures can be endangered by chloride ions. Two phenomena help to keep control of chloride effects. On one hand cements are able to bind chloride ions by their aluminate clinker phases or by the clinker substituting materials. On the other hand resistivity of concrete against chloride penetration can be improved by careful selection of concrete ...

Nomenclature. In molecular formulas water of crystallization can be denoted in differential: "hydrated compound • nH 2 O" or "hydrated compound×nH 2 O" This notation is used when the compound only contains lattice water or when the crystal structure is undetermined. For example Calcium chloride: CaCl 2 • 2H 2 O "hydrated compound(H 2 O) n " A hydrate with coordinated water.
A: According to petrographer Bernie Erlin, copper won''t corrode in concrete unless soluble chlorides are present. When copper is adjacent to steel reinforcement, and an electrolyte such as chloride is present, steel corrosion is likely to occur due to galvanic action. Under these circumstances, you should insulate the copper with a suitable ...
Copper(II) carbonate or cupric carbonate is a chemical compound with formula CuCO 3. At ambient temperatures, it is an ionic solid (a salt) consisting of copper(II) cations Cu 2+ and carbonate anions CO 2− 3. This compound is rarely encountered because it is difficult to prepare and readily reacts with water moisture from the air.
Copper and compounds occur naturally in the environment and is essential to animals and plants. Copper is toxic to many bacteria and viruses. Copper is commonly found as copper (II) in natural waters and the free copper (II) ion is potentially very toxic to aquatic life, both acutely and chronically.
