Introduction of JTG E30-2005

1 General Provisions 1.0.1 This standard is formulated in order to specify the determination of properties and characteristic values of cement and cement concrete for highway engineering. 1.0.2 This standard is applicable to the property tests of cement and cement concrete for highway engineering. 1.0.3 The instrument and equipment applied in this standard are tested and approved by related national measuring departments and testing organization. 1.0.4 The national legal measure units apply this standard. 1.0.5 The sieve meshes adopted in this standard, except ones specified specially, all refer to square-mesh sieve. 1.0.6 The following standards contain provisions which, through reference in this text, constitute provisions of this standard. At time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this standard are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below. 2 Terms and Symbols 2.1 Terms 2.1.1 Fineness A parameter to indicate the fineness degree of cement. Express the fineness of cement specimen with specific surface area or percentage of the mass of sieve residue gained by specified sieve accounting for the original mass of the specimen. 2.1.2 Setting time Time from adding water to losing plasticity of cement slurry 2.1.3 Soundness A physical index to indicate the volume change uniformity after cement hardening. Redwood method indicates the cubical expansion of cement with the normal consistency, which is measured by the relative displacement of two touch needles. and Pat method indicates the cubical expansion of pat under the condition of the normal consistency of cement. 2.1.4 Normal consistency It, consistency for short, is referred to the moisture addition when neat cement paste reaches the required consistency, and it is expressed by the percentage of cement mass and used to determinate the water consumption of cement slurry setting time and soundness. 2.1.5 Cement mortar Mixture of cement, sand and water in a certain proportion. Cement may come with different types; sand may be standard sand or ISO Standard Sand; general water consumption changes with the various requirements. 2.1.6 Roller-compacted concrete A harsh cement concrete shaped by vibroroller compacting. 2.1.7 Slump Sinkage of new shaped concrete mixture under the deadweight action. 2.1.8 Slump spread
