Global cement and concrete additive demand to exceed $11-bn in 2010
World demand for cement and concrete additives is forecast to rise 5.1 per cent per year through 2010 to over $11 billion, an improvement over the performance of the 2000-2005 period, according to a new study by The Freedonia Group Inc, a US-based industry research firm.
According to the report, gains will be fuelled by the increased acceptance of additives in high volume developing markets for cement, such as China, India, Eastern Europe and the Middle East. In more mature markets, higher performance requirements for concrete will prompt greater loadings of additives and the use of higher-value products such as super-plasticizers.
Increasing use of mineral additives
Demand for mineral additives will grow at the fastest pace, fuelled by increased utilisation of blast furnace slag and fly ash as partial replacement for portland cement. The report states that environmental benefits would be the driving factor, as the use of mineral additives provides a beneficial application for waste materials as well as reducing the energy and emissions required to produce cement. Gains for chemical and fibre additives will benefit from penetration into new markets in the developing world, as the concrete industries in these countries become more aware of the benefits of additive use.
North America to lead growth
Among the three major world regions, demand for cement and concrete additives in North America will advance at the quickest pace. The US will be one of the fastest-growing markets for additives, driven by an increased focus on production of more durable concrete and utilisation of mineral waste products. China and India will also rise at an above-average rate. In Japan — the world’s second largest additive market — growth will be restrained by market maturity and weak demand for cement.
