Trade Journals for the Concrete Industry

The Danish market demands wider hollow core slabs for floors, which has been the inspiration for the expansion of the production capacity at CRH Concrete. Hollow core floor slabs are precast elements well known throughout the world and especially in Northern Europe where they enjoy the widest popularity. They have gradually evolved both in terms of size and their fields of application. Since the 80s there has been a continuous drive to increase the thickness of these floor elements with the aim to achieve greater spans with higher loading capabilities. In 1987 the first Slipformer machines able to produce hollow core slabs of 700 mm height were launched, a height that increased to 1000 mm after only a few years.
