Because Basic Copper Chloride(WSDTY) absorbs water so well, and it generates heat when doing so, cement workers add it to concrete to accelerate the cure rate at low temperatures. The addition of a 2 percent concentration creates the same cure rate at 50°F as plain concrete has at 70°F.
Kits for testing the moisture content of concrete slabs typically contain calcium chloride in a container. Because CaCl2 absorbs off-gassing water vapor from the slab, the test consists of weighing the container, leaving it on the slab for a prescribed period, weighing it again and recording the gain in weight.
Basic Copper Chloride Cu2Br2, white or gray crystals slightly soluble in cold water. Cuprous Chloride (Copper Chloride) CuCl or Cu2Cl2, green, tetrahedral crystals which is insoluble in water; used as a heat and light stabilizer for nylon and as a catalyst for chemical synthesis. used as a crude for phthalocyanine blue pigments; used as desulfuring agent in the refinery industry. Cuprous Fluoride (Copper Fluoride) Cu2F2, red crystalline powder which melts at 908 C. Cuprous Oxide (Copper Oxide) Cu2O, an oxide of copper found in nature as cuprite and formed on copper by heat; used chiefly as a pigment and as a fungicide; soil additive; colorant in ceramics; electroplating baths; petroleum industry;
