Chapter 2Construction methodsSILKA walls are composed of standardelements and cut-to-size blocks inaccordance with the previouslyapproved wall drawings. The kickercourse consists of smaller calciumsilicate blocks (standard heights70, 85, 100, 115, 130, 145 and 160 mm).This allows wall parts to be suppliedas semi-prefabricated packages(illustration 1).Walls are constructed using– a crane and useful tools(lump hammer, cold chisel, etc.)– “thin joint mortar” of traditionalcomposition.With this building method, even smoothwalls can be obtained, which areextremely well suited to finishing with:- a thin layer of plaster- tiling straight onto the surface.8SILKA Calcium Silicate Elements
2.1 Ordering and delivery procedureThe building system is offered and soldby Xella per nett m 2 per thicknessdimension. Price calculations arebased on the drawings, which must atleast have a scale of 1:100, supplied bythe contractor or architect.Included in m 2 price:- whole elements and cut blocksdelivered free on site, unloadednext to lorry;- cutting of blocks;- working drawings of walls.Not included are prices of materialaids, thin joint mortar and accessories.They will be quoted separately.Once the client has committed theorder, Xella will make the working walldrawings, based on the drawingssupplied by the customer (illustration 2),of the elements and blocks requiredfor the walls.illustration 1A = elements. These are in standard formats in the working dimensions of1000 x 545/645 mm in various thickness dimensions.B = straight fitting pieces, cut to size from the elements, which makes straight wallendings possible.C = slanting fitting pieces, cut from elements to the desired angles and sizes, mainlyfor use in apexes of gablesD = kicker course blocks. To be used for construction of the first layer of blocks.This functions as a fitting edge for the elements and a level base.Advantages of building withSILKA calcium silicate elements:simple building technique;high compressive strength;fast, rational and non-intensive labour;easy build ability with thin joint mortar;thin wall finishing (2–3 mm plaster finish);all round use;little preparation;flexible;no large investments in equipmentsuch as formwork and heavy cranes;‘slimmer’ walls than traditionalbuilding techniques versions;less building moisture;no waste.SILKA Calcium Silicate Elements9
