The new products are suitable for the binding of aerated concrete blocks and glass bricks. Due to the strong interest producers continue to develop new products. The Maestro brand products hold a 5-6 per cent market share according to surveys. The figure is expected to reach 10 per cent in 2007 and between 15 and 20 per cent in 2010.
