Standard 440 x 100 x 215mm units can be laid to a radius. The practical limits are determined by the acceptable face width of the perpends on the outer radius and the amount of overhang between courses. For example a 4.5m radius would mean a vertical perpend width of 20mm, and an overhang of 5½mm. The tighter the radius the larger the overhang.
For more information see page 6 of the Forticrete Masonry Design Guide, which you can find under Resources.
There are currently 10 solutions for aggregate concrete blocks in the Robust Standard Details, 3 for dense masonry (1850-2300kg/m³).
Forticrete can offer dense aggregate blocks to meet these 3 situations.
We can offer a U-shaped Lintel block in our Architectural Masonry range, in 100, 140 or 215mm widths. This can then be used to create a reinforced lintel unit capable of spanning openings yet still allowing the aesthetics of the masonry wall to be kept.
For the removal of general dirt and grime a mild detergent such as 'Sugar Soap' may be used in conjunction with a stiff bristle brush. For more persistant staining there are certain products on the market which can be used e.g. CM1 Mortar Cleaner from Hydron Protective Coatings.
Under no circumstances should acid or non-approved cleaners containing acid be applied to Forticrete Architectural Masonry, Cast Stone, Precast or Astra-Glaze products.
For polished masonry the use of a wooden or plastic scraper is recommended for the removal of mortar or material stuck to the face of the product ensuring that the surface is not scratched.
A proprietary marble cleaner can be used to restire the product's sheen followed by a lambs wool buffer with bee's wax polish.
Any mortar that encroaches ontot the surface of the masonry during construction should be cleaned off as soon as possible.
Forticrete can offer a comprehensive cutting service for the creation of special shapes and sizes. If you do need to cut masonry on site we would always recommend the use of a clipper bench station, with a Diamond tip blade and a fresh supply of clean uncontaminated water. Polished masonry should not be cut on site as the process can affect the appearance of the units.
Sample slips, blocks and panels can be obtained by contacting our Sales Office on 01429 838001, or alternatively by completing the online sample request form.
The nature of concrete masonry is such that it will shrink and because of this it is necessary to accommodate movement control joints in the building design. BS 5628-3:2005 sets out the parameters for the positioning of control joints, and as a rule, vertical joints to accommodate horizontal movement should be provided at 6 to 9m intervals.
Please contact the Forticrete Technical Department for further information: 0800 262136.
The lack of cross bonding from the block directly above or below each unit will affect the flexural strength of the panel considerably. Experience has shown that bed joint reinforcement should be included at every other course (450mm centres) for the full height and width of the panel.
Forticrete can offer a DCM cellular/ Hi-Light block that weighs 19.8kg, see our sizes and weights brochure.
For all Forticrete masonry, up to and including 22.5N/mm² strength, a cement, lime, sand mix, grade (iii) mortar (1:1:5/6) as per Table 13 BS 5628-3:2005 should be specified/used.
