GRC产品制造、养护和试验规范(中英两语版).doc

Introduction （引言） Scope （范围） This specification covers the requirements for the manufacture, curing and testing of GRC products. It gives detailed requirements for five grades of GRC manufactured by two different methods: 本规范包括GRC产品的制造、养护和试验要求。它给出了用两种不同方法制造的五个等级GRC的详细要求。 X ‘Spray’ Grades 18 and 18P “喷射”等级18和18P X ‘Premis’ Grades 10 and 10P “预混”等级18和18P X ‘Premis’ Grade 5 “预混”等级5 ‘P’ refers to the use of acrylic polymer emulsion in the GRC mix design. The specification covers mixes with and without polymers. Selection of the applicable grade should be made by the purchaser in consultation with the producer and after consideration of the engineering design of the product. ‘P’表示在GRC配合比中使用丙烯酸聚合物乳液。本规范包括含有或不含有聚合物的混合料，适用等级的选择应该由购买方和生产商在考虑产品的工程设计之后协商确定。 1.2 References （参考文献） Standards and other publications referred to in this specification are listed in appendix D. 本规范中涉及的标准和其它规范在附录D中列出。 1.3 Definitions（定义） Uncured state（未养护状态） The stage in the manufacture of GRC when all physical processes that could alter composition of the material are complete but the fibre can still be separated from the matrix by the action of running water. 在GRC制造过程中，所有可能改变材料组分的物理过程完成、但是通过流水纤维仍然能够从基材中分离的阶段。 Aggregate/cement ratio（集料/水泥比（集灰比）） The ratio of the mass of total dry aggregate to the mass of dry cement in the GRC. GRC中总的干集料质量与干水泥质量之比。 Water/cement ratio（水灰比） The ratio of the mass of total water to the mass of dry cement in the GRC in the uncured state. When pozzolanic fillers are used they can be considered as cementitious and the water/cement ratio can be expressed as a water/total binder ratio, examples of such pozzolanic fillers are pulverized fuelash, microsilica and metakaolin. 在未养护状态的GRC中，总的水质量与干水泥质量之比。当使用火山灰质填料时，它可被考虑作为胶凝材料，水灰比可用‘水/总胶凝材料’比表示；这种火山灰质填料有磨细粉煤灰、微硅粉和偏高岭土。 Glass fibre content by weight (WF)（玻璃纤维质量含量（WF）） The ratio (expressed as a percentage) of the mass of glassfibre to the mass of GRC in the uncured state. 玻璃纤维质量与未养护状态GRC质量之比（用百分数表示） Characteristic p
