In 2012, ready-mix concrete accounted for around 7 per cent share of the overall concrete market in India. The market share of ready-mix concrete is expected to further increase on account of anticipated average annual growth of 20 per cent in ready-mix concrete consumption over the next five years.Superplasticisers are generally chloride free, which makes them appropriate for pre-stressed concrete. The reason being, chloride accelerates the oxidation reaction in metals, which results in corrosion, thereby affecting the structural strength. Growing concrete consumption in India, coupled with increasing use of superplasticisers, is expected to positively impact admixtures market in the country.´The Indian admixtures market is dominated by naphthalene based admixtures on account of their cost-effectiveness compared to PCE based admixtures as well as improved workability in comparison with lignosulphonates. By 2019, PCE based admixtures are expected to gain more ground due to increasing product innovation in terms of developing low cost PCE based admixtures, rising naphthalene prices and growing need for faster vertical construction activities in the country,´ said Mr. Karan Chechi, Research Director with TechSci Research, a global management consulting firm.
