Chapter 1 Introduction The natural components of SILKA elements are sand and lime. Both raw materials are available in an almost unlimited supply. However, the requirements for this type of sand are less stringent than they are for many other applications. 1.2 Production process autoclave for hardening. This is done elements, environmentally The modern production process starts by means of steam under high friendly products: with the fully automated measuring pressure, to obtain the end product. SILKA blocks and elements consist and mixing of quicklime, sand and The ‘SILKA block’ made in...

1.4 SILKA calcium silicate elements The elements come in various thicknesses with a working length of 1000 mm and in heights of 545 mm and 645 mm. SILKA is a lime-sand product, with a very smooth finish, capable of delivering significant onsite time and money savings upon completion.

1.5 Clamping devices and dowels At the top end of each SILKA-element there are 2 holes, every 500 mm, for mechanical lifting and for dowel placement. Dowels In the system, dowels are used for simplifying the exact placement of the SILKA elements and to prevent them from ‘floating’. The dowels are manufactured from recyclable synthetic material (polypropylene); the blue colour is obtained by adding a cadmium-free colouring agent. A maximum of 1,85 dowels (1 per whole element) is needed per m2. SILKA Calcium Silicate Elements 7
