MISCELLANEOUS CONCRETE STANDARD SPECIFICATION ROADWORKS DoI REFERENCE TEXT December 2015 Page 80 11 MISCELLANEOUS CONCRETE 11.1 STANDARDS Conform to the following Standards and Publication unless specified otherwise: AS 1012 Methods of testing concrete AS 1141 Methods for sampling and testing aggregates AS 1289 Methods of testing soils for engineering purposes AS 1379 The specification and manufacture of concrete AS 1478.1 Chemical admixtures for concrete AS 2349 Method of sampling portland and blended cements AS 2350 Methods of testing portland and blended cements AS 2758.1 Aggregates and rock for engineering purposes - Concrete aggregates AS 2876 Concrete kerbs and channels (gutters) - Manually or machine placed AS 3600 Concrete structures AS 3610 Formwork for concrete AS 3972 Portland and blended cements AS/NZS 4671 Steel reinforcing materials NTMTM NT Materials Testing Manual NTTM NT Test Methods 11.2 GENERAL This section specifies miscellaneous minor concrete works and does not apply to buildings or bridges. It is for incidental Concrete Works. It should not be used for concrete pavements. Concrete pavements require a specific "one off" specification developed as required. 11.3 MATERIALS Provide manufacturer's test certificates for quality of cement, aggregate and reinforcement. 11.3.1 Cement Type GP or GB to AS 3972. Store cement in watertight containers or shelters until used. Do not mix or store special cement with normal Portland cement. 11.3.2 Fine Aggregate Clean, hard, tough, durable, uncoated grains, homogeneous in quality, free from clay, dirt and organic material. 11.3.3 Coarse Aggregate Clean, hard, durable, crushed stone or gravel, free from clay, dirt and organic material. 11.3.4 Water Clean and free from oil, alkali, organic or other deleterious substances. 11.3.5 Chemical Admixtures - Hold Point Hold Point - Do not use admixtures without obtaining prior written approval from the Superintendent. Admixtures and their use must conform to AS 1478.1. Where two or more chemical admixtures are proposed for incorporation into a concrete mix, their compatibility must be certified by the manufacturers. Store admixtures in accordance with the manufacturers recommendations. 11.3.6 Reinforcement Hold Point Standard: To AS/NZS 4671 Supply, cut, bend and fix steel reinforcement as specified. Secure reinforcement and bar supports to prevent displacement during construction and concrete placement. Hold point - Do not place concrete until the reinforcement has been inspected by the Superintendent. 11.3.7 Recycled Crushed Glass (RCG) Clean, hard, durable RCG free from clay, dirt and organic material. Source the material from glass food and beverage containers, drinking glasses, and window (or flat) glass and plain ceramic. Do not use glass from hazardous waste containers, reinforced and laminated glass, light bulbs, fluorescent tubes and cathode ray tubes. The source glass must be free of debris and contaminants such as paper and cardboard, plastic, fabrics, residues from original contents and toxins. Use RCG conforming to Specifications for Recycled Crushed Glass as an Engineering Material Section 9 available at http://www.nt.gov.au/infrastructure/techspecs/do cuments/ARRB_specifications_RCG.pdf 11.4 CONCRETE 11.4.1 Ready-mix Concrete Refer to PROJECT SPECIFIC REQUIREMENTS in the RFT for special requirements. http://www.nt.gov.au/infrastructure/techspecs/documents/ARRB_specifications_RCG.pdf http://www.nt.gov.au/infrastructure/techspecs/documents/ARRB_specifications_RCG.pdf
