Canoeing down the river in your new concrete canoe! What? You read it right. Every year, the American Society of Civil Engineering sponsors a nationwide Concrete Canoe Competition. Rowen University, Glassboro, N.J., has competed for the last six years and made it to the nationals four consecutive times. This year, Concrete Chemicals of California is rooting for Rowen too — because Rowen’s canoe will be colored with Concrete Chemicals’ Robin Blue colorant. The students used about 120 pounds of Type 1A grey cement, plus another 75 pounds of slag and fly ash and some Robin Blue colorant. Concrete Chemicals of California, www.liquiblack.com, a producer of liquid pigments for concrete, swimming pool plaster, and other cement products, usually sells colors for the cement around the water, not the object in the water.
