This European Standard specifies requirements, test methods and compliance criteria for cement bound granular mixtures used for construction and maintenance of bases and sub-bases of roads, airfields and other trafficked areas.
This European Standard specifies the characteristics of cement bound granular mixtures (CBGM) by reference to the properties of their constituents, the mixture and the properties of specimens of the mixed materials.
NOTE In addition to conforming to the requirements of this European Standard cement bound granular mixture may have other requirements, not included in this European Standard, which may be required by national regulation. The additional requirements may include any requirements selected from the following:
-frost damage resistance;
-compacity (as defined in EN 14227-2);
-workability period (measured in conformity with prEN 13286-45);
-immediate bearing index (measured in conformity with prEN 13286-47);
-such other requirements as are referred to within this European Standard, as being the subject of national regulations.

This European Standard specifies "slag bound mixtures" for roads, airfields and other trafficked areas and specifies the requirements for their constituents, composition and laboratory performance classification. In this European Standard slag refers to slag from the iron and steel industry.

EN 13286-43:2003 Unbound and hydraulically bound mixtures - Part 43: Test method for the determination of the modulus of elasticity of hydraulically bound mixtures
This standard specifies a method for the determination of the modulus of elasticity of test specimens of hydraulically bound mixtures (HBM). The standard applies to specimens made from either laboratory or production mixes with a maximum aggregate size of 31,5 mm. The determination of the modulus is obtained by either of the two following methods: - by compression or in direct tensile test; - by indirect tensile test.

Environmental Hazards: The Fluid Dynamics and Geophysics of Extreme Events (Lecture Notes Series, Institute for Mathematical Sciences, National University of Singapore)
Author: H. K. Moffatt, Emily Shuckburgh | Size: 7.0 MB | Format:PDF | Publisher: World Scientific Publishing Company | Year: 2011 | pages: 300 | ISBN: ISBN10: 9814313289 & ISBN13: 9789814313285
Book Description:
One of the priority areas of ICSU (The International Council for Science) is Natural and Human-Induced Environmental Hazards and Disasters. The School - held at the Institute for Mathematical Sciences, Singapore from 20 April to 2 May 2009 - on which this volume is based on was sponsored by ICSU and by its members from IUTAM (the International Union of Theoretical and Applied Mechanics) and IUGG (the International Union of Geodesy and Geophysics). This volume provides an indepth graduate-level introduction to the fluid dynamics and geophysics of hazards such as tropical cyclones, flooding, atmospheric pollution and tsunamis. It also includes discussion of the possible effects of climate change on these phenomena. Indeed, the current importance of this area is of great public concern.

Generalized Plasticity deals with the plasticity of materials and structures. It is an expansion of the "Unified Strength Theory to Plasticity Theory", leading to a unified treatment of metal plasticity and plasticity of geomaterials, generally. It includes the metal plasticity for Tresca materials, Huber-von-Mises materials and twin-shear materials and the geomaterial plasticity for Mohr-Coulomb materials, generalized twin-shear materials and the Unified Strength Theory.

This new book builds on the original classic textbook entitled: An Introduction to Computational Fluid Mechanics by C. Y. Chow which was originally published in 1979. In the decades that have passed since this book was published the field of computational fluid dynamics has seen a number of changes in both the sophistication of the algorithms used but also advances in the computer hardware and software available. This new book incorporates the latest algorithms in the solution techniques and supports this by using numerous examples of applications to a broad range of industries from mechanical and aerospace disciplines to civil and the biosciences. The computer programs include both Fortran 77 and MATLAB. In addition the core text provides up-to-date solution methods for the Navier-Stokes equations, including fractional step time-advancement, and pseudo-spectral method
