US cement and concrete additive demand will grow 6.4 percent annually through 2012, as construction activity rebounds from a low 2007 base. Chemical additives will stay the top segment, led by water reducers such as superplasticizers. Mineral additives will grow faster, paced by waste materials such as fly ash and blast furnace slag.Th is study analyzes the $2.3 billion US cement and concrete additive industry. It presents historical demand data (1997, 2002 and 2007) and forecasts for 2012 and 2017 by type (e.g., surfactants and dispersants, inorganic chemicals, fly ash, blast furnace slag, gypsum, silica fume, fibers), function (e.g., water reducers, set controllers, coloring agents, air entrainers) and market (e.g., building construction, highways and streets). The study also considers market environment factors, details industry structure, evaluates company market share and profiles 35 industry competitors, including BASF Admixtures, Grace Construction Products and Headwaters.
