Structural Reinforced concrete
For Structural Reinforced concrete applications please contact us to discuss your requirements or refer to BS 8500 Part 1.
Notes 40mm aggregate may be used in mass concrete or large foundations. When concreting steep slopes, in some cases an S1(25mm slump) concrete should be used. However this will require vibrating equipment to compact it adequately. On flat surfaces, S3 (125mm slump) concrete may be specified if the concrete is to be compacted by hand. In a few parts of the UK, local materials may not be suitable for the production of these high strength concretes. In such circumstances, Mix B in the Ministry of Agriculture's Standard Costs, Part 1.: Specification should be used. Similar to C35A. Meets the requirement of BS 8007 code of practice for design of concrete structures for retaining aqueous liquids demanded by the Control of Pollution Regulations 1991. Where the concrete is subject to even occasional de-icing salts, designated mix PAV 1 is recommended. Use low workability mixes for acid and abrasion resistance. Take care to ensure full compaction of the fresh concrete and proper curing for several days. Use 10mm aggregate for this application.
