This study therefore investigated and improved cementitious properties of pozzolan blended with calcium hydroxide, gypsum and cement in order to extend its use from low strength mortars to concrete works which can be used for low to medium rise structural applications. Characterization, strength tests and durability tests were performed on pozzolan mixtures under laboratory conditions and the effects of adding gypsum to pozzolan and calcium hydroxide mixtures on the compressive strength and durability of cured concrete specimens were investigated.

As every civil engineer knows, Portland Cement is the most versatile and important material of construction, and will probably remain so far into the future. Yet few books, if any, exist that offer an in-depth analysis of the mixing and testing methods of this vital hydraulic cement. This statement, written about the first edition of Engineere

Concrete has clearly emerged as the most economical and durable material for the building of the vast majority of marine structures. Reinforced concrete too has overcome the technological problems making it a suitable material for the construction of advanced marine structures such as offshore drilling platforms, superspan bridges and undersea tunn

This monograph describes cement clinker formation. It covers multicomponent systems, clinker phase structures and their reactions with water, hydrate composition and structure, as well as their physical properties. The mineral additions to cement are described as are their influence on cement-paste properties. Special cements are also discussed. The microstructure of concrete is then presented, and special emphasis is given to the role of the interfacial transition zone, and the corrosion processes in the light of cement-phase composition, mineral additions and w/c ratio. The admixtures' role in modern concrete technology is described with an emphasis on superplasticizer chemistry and its cement-paste rheological modification mechanism. Cement with atypical properties, such as calcium aluminate, white, low energy and expansive cements are characterized. The last part of the book is devoted to special types of concrete such as self compacting and to reactive powders.

Cement is the basis of the building and construction industry and of fundamental importance for many civil engineering applications. As such, the cement industry is one of the key industries worldwide necessary for the current and future sustainable development of society. Despite its undisputed importance, the cement industry is one of those industrial branches predominately responsible for high energy consumption and excessive generation of large amounts of carbon dioxide and other contaminants that significantly endanger human health and the environment and contributes to global warming.In this context, nanomaterials, polymeric materials, and natural additives are being used for cement enhancement in various applications. This book examines these novel materials and their optimization, characterization, and sustainable application in the building industry and for stabilizing hazardous waste.

Until now, no study has been made of the construction techniques of the Nabataean freestanding buildings and the rock-cut monuments of Petra, Jordan (built from the 1st cent. BC to the 2nd cent. AD). Their technical features were documented by fieldwork,and this evidence was then analysed to determine precisely when and why these features appeared or evolved. This leads to explaining how the Nabataeans developed their architecture, and what types of construction techniques they used to bring Petra's architecture to its peak. The historical and geographical context for the architecture of Petra is presented, with a summary of previous scholarship on the site. The focus moves to the building materials used by the Nabataeans which are found toinfluence the construction techniques they developed. This is followed by a detailed discussion of quarrying and the rock-cut techniques. The procedures for dressing ashlar blocks and the facades of the rock-cut monuments are analysed to determine the tools used by the builders, as well as the lifting devices necessary for construction of the freestanding buildings. The technical aspects of the construction of walls, columns, floors, the anti-seismic and stabilising techniques developed by theNabataeans are considered. Finally, the construction of roofs is examined in detail. The results of the study reveal the sources of the building techniques used at Petra and why they were further developed there.THREE REVIEWS OF HOW PETRA WAS BUILT:J. J. Coulton, Formerly Reader in Classical Archaeology, University of Oxford. "Using his practical experience as an architect as well as extensive and detailed fieldwork, Dr Rababeh has provided an illuminating analysis of Nabataean buildings, showing how they drew on, and modified, previous Levantine and Hellenistic methods to suit local materials and local requirements." Judith McKenzie, author of The Architecture of Petra: "Other books cover the architectural styles of the monuments of Petra. Shaher er-Rababeh's is the first to focus on the subject of how they were built, both the rock-cut tombs and the freestanding buildings. He methodically presents the results of months of first-hand examination of the evidence. Each aspect of building construction is analysed making wide-ranging use of recent scholarship on ancient building techniques. Just as the Nabataeans made their desert environment habitable with complex water-collection systems, they refined local, Egyptian, Greek and Roman construction techniques to suit the city's rose red sandstone and other available building materials. Rababeh shows the Nabataean construction techniques were just as distinctive in their details as the style of their architecture - which they created from classical Alexandrian andNear Eastern elements. He makes interesting discoveries. The stone cut awaywhen the tombs were carved was used to erect the city's freestanding buildings.Rababeh shows how Petra has the earliest extensive examples of timber used tostrengthen stone masonry buildings, as later seen on the Ka'ba at Mekka."Ehud Netzer, author of Nabataeische Architektur: "This comprehensive study of the building systems in the Nabataean world is a pioneering work. It deals with all aspects from wall foundations to roof tiles; simple constructions and monumental ones; freestanding buildings and monuments cut into the rock. Shaher's new book widens our knowledge of the enchanted world of Nabataean architecture."

Pozzolanic and cementitious admixtures are becoming increasingly important to enhance the environmental friendliness of portland-cement concrete and to improve workability, durability, and other properties of the material. This book provides a simple but comprehensive review of the composition and performance of important pozzolanic and cementitious admixtures, such as fly ash, granulated blast-furnace slag, natural pozzolans, silica fume, rice-husk ash and metakaolin.
