BS 882:1992 © BSI 6 March 2002 1 0 Introduction When specifying aggregates in compliance with this standard, there may be a need to specify or approve certain additional quality requirements or narrower grading limits within one of those inTable 4 for sands,

Gives definitions, information to be provided by the supplier and advice on special considerations and chloride content. This Standard specifies sampling and testing, quality requirements and grading of coarse, fine and all-in aggregate for use in concrete.

Materials, articles, samples and test certificates may conform with standards other than the British Standards referred to in this Specification provided the alternative standard is at least equivalent.

The drafting of this Construction Standard has made reference to the following British Standards (BS), European Standards adopted as British Standards (BS EN), publication of BRE, National Standard of the People’s Republic of China (GB), publication from International Union of Laboratories and Experts in

Specifies the property requirements, quality control requirements and testing methods of aggregates for use in production of concrete. Covers coarse and fine natural aggregates and coarse recycled aggregates having an oven-dried particle density not less than 2,000 kg/m3.

Graded aggregate complying with table 4 of BS 882:1992 as follows: DN 100 14mm to 5mm DN 150 to DN 525 20mm to 5mm or 14mm to 5mm DN 600 and above 40m to 5mm or 20mm to 5mm or 14mm to 5mm ... TO BS EN124, REFER TO MANHOLE SCHEDULE FOR SIZE & CLASS 2-4 COURSES CLASS B ENGINEERING BRICKS, CONCRETE BLOCKS OR PRECAST …

Processed granular bedding and sidefill materials for flexible pipes. Minimum recommended trench widths for structured wall pipes in poor ground conditions.

cements complying with BS 12 [3] or BS 4027 [4] and natural aggregates complying with BS 882 [5], or coarse air-cooled slag complying with BS 1047 [6]. It does not deal with special materials or special concretes such as lightweight aggregate concrete, or with flowing or pumped concrete. Guidance is given on the application of the method to mixes

Methods for the assessment of the compaction performance of a roller and recommended procedures for the measurement of the temperature of bituminous mixtures.

Natural stone aggregate forms the bulk volume of concrete and has contri-buted to the increased cost of concrete production. This has led to the search for alternate aggregates such as lateritic stone for concrete production.
