ASTM C150/C150M-11 Standard Specification for Portland Cement
Size: 200 KB | Format:PDF | pages: 9
This specification covers ten types of portland cement: Type I, Type IA, Type II, Type II(MH), Type II(MH)A, Type IIA, Type III, Type IIIA, Type IV, and Type V. The cement covered by this specification shall only contain the following ingredients: portland cement clinker; water or calcium sulfate, or both; limestone; processing additions; and air-entraining addition for air-entraining portland cement. Portland cements must meet various physical and chemical requirements which are detailed in this specification. Examples include limits on aluminum oxide, ferric oxide, magnesium oxide, sulfur trioxide, tricalcium silicate, dicalcium silicate, tricalcium aluminate, and tetracalcium aluminoferrite. Applicable properties enumerated in this specification will be determined by the following test methods: air content of mortar, chemical analysis, compressive strength, false set, fineness by air permeability, fineness by turbidimeter, heat of hydration, autoclave expansion, time of setting by Gillmore needles, time of setting by Vicat needles, sulfate resistance, calcium sulfate, and compressive strength. The cement shall be stored in such a manner as to permit easy access for proper inspection and identification of each shipment, and in a suitable weather-tight building that will protect the cement from dampness and minimize warehouse set.

PAS 24:2007+A2:2011 Enhanced security performance requirements for door assemblies. Single and double leaf, hinged external door assemblies to dwellings
he concept of “enhanced security” in this Product Assessment Specification (PAS) is based upon a relationship between resistance to forced entry by human intervention techniques and resistance to entry under multi-directional loading and hard and soft body impacts.
The PAS specifies test methods and acceptance criteria relevant to the enhanced security performance of single and double leaf, single swing, hinged, external door assemblies to dwellings, inward and outward opening, with or without integral or coupled side panels and fanlights. It includes double leaf door assemblies where the size, construction or configuration of the active and inactive leaves are identical or differ. The enhanced security performance requirements in this specification are not material-specific.
This PAS is applicable to new door assemblies as manufactured and prior to installation. It is only applicable to complete door assemblies or a range of door assemblies.
The ability to gain entry by manipulation of a cylinder is address in this PAS. However, entry by picking, by deliberate breaking of glass or by attach on the frame fixing methods is not.
This PAS is not a test of components performance or installation requirements.
This PAS excludes double swing doors, sliding doors, sliding folding doors, pivoted doors and doors with two halves (stable door). It does not cover door assemblies where any frame member is longer than 3 m.
Contents for PAS 24:2007+A2:2011 includes:

This book contains some of the papers presented at the International Conference on Underground Spaces–Design, Engineering and Environmental Aspects, held on the Campus of the Wessex Institute of Technology in the New Forest. The Conference was launched to discuss not only the structural and environment material characterization aspects but also the trends regarding the development underground spaces.

This book provides the most recent information about concrete’s history in the green building movement, state-of-the-art methodologies, and best practices. The history of cement manufacturing and the use of concrete are discussed to provide a context for today’s current practices. Continuing pressures on the construction industry to reduce waste have resulted in an increase in the amount of concrete that is recycled or reused Refurbishing or reusing structures is the least waste option This book outlines the variety of ways that concrete is easily and affordably reused. Work is under way within the precast industry with the aim of making it possible to lease concrete products so that they can be returned and/or reused.

Nonlinear Mesoscopic Elasticity: The Complex Behaviour of Rocks, Soil, Concrete
Author: Robert A. Guyer, Paul A. Johnson | Size: 15.7 MB | Format:PDF | Publisher: Wiley-VCH | Year: 2009 | pages: 410 | ISBN: 3527407030
Nonlinear mesoscopic elasticity (NME) is the identifier of a collection of extreme/unusual elastic behaviors. The purpose of this book is to describe these behaviors as seen in particular physical systems, to suggest generalization beyond the particular based on a simple picture of the underlying physics, and to provide an analysis/theoretical framework for assessment of behavior and for the description of experiments. The behaviors that are associated with NME are many; eight examples are shown. The physical state of NME systems is specified in a multidimensional space of parameters, for example, length scale, time scale, the size of stress/strain fields, the strength of internal forces, etc. The boundaries of this space are set. At the end of the following overview we will provide an outline of the book.

Dear Admin. I have some minor suggestion for you about Ebook Post Generator.
Maybe you can add additional information to post generator like
Quality of book? Is it searchable, scan quality or what?. maybe you can add rate dropdown like 3(highest) for searchable text and 1 for scan copy book.
Is it bookmark? the answer only yes and no. you can just add check book to this item.
