適用范圍：This part of BS 8204 gives recommendations for constituent materials, design, work on site, inspection andtesting of concrete bases that are to receive in situ wearing screeds of the following types:a) concrete (see BS 8204-2);b) polymer modified cement (see BS 8204-3);c) terrazzo (see BS 8204-4);d) mastic asphalt (see BS 8204-5);e) synthetic resin (see BS 8204-6);f) magnesium oxychloride;g) pumpable self-smoothing screeds (see BS 8204-7);and for bases and levelling screeds that are to receive flexible floor coverings such as:h) textiles;i) linoleum;j) polyvinyl chloride;k) rubber;l) cork;and rigid floorings such as:m) wood block and strip;n) laminate floor coverings;o) ceramic tiles;p) natural stone.It applies to ground-supported and suspended concrete floor bases.This part of BS 8204 includes the use of concrete and levelling screeds made with lightweight aggregatesconforming to BS EN 13055-1. Where the recommendations differ from those for normal weightaggregates, these are given in Annex A.Recommended methods for the assessment of levels and surface regularity and for the determination ofin situ crushing resistance (soundness) are given in Annex C, Annex D and Annex E.This part of BS 8204 is not intended to provide guidance on the structural design or related construction ofconcrete ground-supported floors or suspended slabs. Information on these aspects is given in BS 8110-1and reference [4]. The specification of concrete for base slabs is given in BS 8500-2. The recommendationsin this code of practice relate to those other aspects of design and construction of concrete slabs that affectthe performance of the overlying levelling or wearing screed.See Part 3 for polymer modified cementitious levelling screeds.
