Available in PDF, EPUB and Kindle. Book excerpt: In spite of the increasing use and demand for lightweight aggregate concrete (LWAC), there is still a lack of adequate explanations to understand the mechanisms responsible for the strength and durability properties of LWAC. This book is written to give an overall picture of LWAC, from the historical background, aggregate production, proportioning and production of concrete, to applications in structures. Physical properties and chemical durability are described in detail. The physical properties include density, strength, shrinkage, and elasticity. Chemical durability includes resistance to acids, chloride ingress, carbonation, and freeze-thaw resistance. Fire resistance is also included, which is seldom considered, but is a very important aspect of the safety of the structure. Microstructure development and its relation to the durability properties of LWAC generally are not highlighted in the literature. The development of bonds, the microstructure with different binder systems, and different types of lightweight aggregates are explained. They show how lightweight aggregate concrete differs from normal weight concrete. The chapters on chloride ingress and freeze-thaw resistance are detailed because of the use of LWAC in offshore construction. The economical aspects of using LWAC are also reviewed. Emphasis is placed on the fact that although the cost of LWAC is high, the total cost of construction has to be considered, including the cost of transport, reinforcement, etc. When these are considered then LWAC becomes cheaper and attractive. The life cycle cost of the concrete is another consideration for calculating long-term savings on maintenance costs.

Available in PDF, EPUB and Kindle. Book excerpt: This volume contains studies on the evolution and function of lightweight constructions of planktonic and other organisms, and examples of how they can be used to create new solutions for radical innovations of lightweight constructions for technological application. The principles and underlying processes responsible for evolution and biodiversity of marine plankton organisms are highly relevant and largely unresolved issues in the field of marine science. Amongst the most promising objects for the study of evolution of stable lightweight constructions are marine organisms such as diatoms or radiolarians. Research in these fields requires interdisciplinary expertises such as in evolutionary modelling, paleontology, lightweight optimization, functional morphology, and marine ecology. Considerable effort and expert knowledge in production engineering or lightweight optimization is necessary to transfer knowledge on biogenic structures and evolutionary principles into new lightweight solutions. This book show methods and examples of how this can be achieved efficiently.

Available in PDF, EPUB and Kindle. Book excerpt: Post-war Europe and Asia have seen the rapid development of German and Japan from a war torn countries into two of the most powerful nations in the world. Their achievement is nothing short of miraculous. However, as the two most populated countries; China and India, transform themselves into Asia powerhouses, cement and concrete will be their brick and mortar to sustain their double digit growth in economy.This book summarizes the history and development of cement and concrete. From prehistoric period to today, from ancient Egypt and Rome period to China, over tens of thousands of years of human civilization in the form of the gelled material (cement, concrete).The book is divided into seven chapters, including more than 300 references. Chapter 1 introduces the prehistoric gelled material development; Chapter 2 is about the birth of Portland cement and the technological application; Chapter 3 introduces the important role that concrete played in the human society developing process; Chapter 4 subdivides the performance and the wide application of different function of cement and concrete; Chapter 5 focuses on northern Europe, especially the history of Norwegian cement; Chapter 6 elaborates the development of concrete in China and its impact in the world's ancient civilizations history; Chapter 7 describes the development prospect of cement and concrete.

Available in PDF, EPUB and Kindle. Book excerpt: Author Biography: Dr. Mohammad Abdul Mannan was born at a simple family of a small village, Aktarpur, Rangiarpota, Jibonnagar, Chuadanga, Bangladesh. He has obtained B.Sc. (Civil Engineering) degree with first class, MSc in Civil Engineering and PhD in Concrete technology. He has started carrier as lecturer at BIT Rajshahi (now RUET), Bangladesh followed by AJP consulting firm, then Universiti Malaysia Sabah (UMS) and is now a Professor of Department of Civil Engineering, Universiti Malaysia Sarawak, Malaysia. He is the inventor of few construction products. Based on 30 years of experience in teaching, professional practice and research, his vision is to be excellence in research on Innovative Construction Material and Structure. Book Description: Due to a high demand in construction and furniture industries worldwide, natural resources such as stones and wood as non-renewable resources are being depleted. Thus, researchers are focusing on renewable resources as alternative materials. As such, the utilisation of abundant solid wastes and byproducts, which are discharged from agriculture, industry and municipalities present an alternative to the conventional materials for the construction and furniture industries. These solid wastes and byproducts, when properly processed have shown to be effective and can readily meet design specifications. Agricultural solid wastes from oil palm distributors such as Oil Palm Shell (OPS) and Empty Fruit Bunch (EFB), which are abundant in agro-based countries, present an interesting alternative to the conventional aggregate in lightweight concrete and artificial plank production, respectively. At present, palm oil producing countries are Barkina Faso, Benin, Burundi, Cameroon, Central African Republic, Colombia, Costa Rica, C�te d'Ivoire, Democratic Republic of Congo, Ecuador, Equatorial Guinea, Gabon, Gambia, Ghana, Guinea Bissau, Guinea, Honduras, India, Indonesia, Liberia, Malaysia, Mexico, Nigeria, Papua New Guinea, Peru, Republic of Congo, Senegal, Sierra Leone, Tanzania, Thailand, Togo, Uganda, Venezuela and others. In Malaysia, oil palm plantations cover over 5 million hectares, and annual production of OPS as solid waste from 450 oil palm mills is more than 6 million tons. This large amount of OPS as a renewable green aggregate can contribute to overcoming the over dependence on depletable resources for concrete production. The civil engineering projects are of a larger scale; they need sustainable materials in order to gain a greater momentum of growth. The major technical characteristics of OPS solid waste must be primarily understood before each particular use. Therefore, there is a need to highlight the importance of OPS to be used in the construction industry.

Download or read book Development and Implementation of Lightweight Concrete Mixes for KDOT Bridge Applications written by Sarah Jo Grotheer and published by . This book was released on 2009 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: As of 2005, 23% of the bridges in the Kansas infrastructure are classified as structurally deficient or functionally obsolete according to the ASCE Infrastructure Report Card (ASCE, 2008). One alternative to replacing the entire bridge structure is replacing only the superstructure with lightweight concrete. This option is more economical for city, county, and state governments alike. Replacing the superstructure with lightweight concrete can oftentimes allow the bridge rating to be upgraded to higher load capacities or higher traffic volumes. Furthermore, lightweight concrete can be used initially in a bridge deck to provide reduced weight and a lower modulus of elasticity, therefore lower cracking potential. The Kansas Department of Transportation is interested in the potential benefits of using lightweight aggregate concrete in Kansas bridge decks and prestressed bridge girders. This research project used three types of lightweight aggregate to develop lightweight concrete mixtures for a bridge deck and for prestressed bridge girders. Two of the lightweight aggregates were expanded shale obtained locally from the Buildex Company. One deposit was located in Marquette, Kansas, and the other in New Market, Missouri. The third lightweight aggregate source was expanded slate obtained from the Stalite Company in North Carolina. Aggregate properties including absorption, gradation, and L.A. Abrasion were evaluated. Over 150 lightweight concrete mixtures were created and tested and several mix design variables such as water-to-cement ratio, cement content, and coarse-to-fine aggregate ratio were evaluated. From these results, optimized bridge deck and optimized prestressed concrete mixtures were developed for each type of lightweight aggregate. Special concerns for lightweight aggregate concrete are addressed. These optimized concrete mixtures were then tested for KDOT acceptability standards for the concrete properties of compressive strength, tensile strength, modulus of elasticity, freeze-thaw resistance, permeability, alkali-silica reactivity, drying shrinkage, and autogenous shrinkage. All concrete mixtures performed satisfactorily according to KDOT standards. In addition, an internal curing effect due to the moisture content of the lightweight aggregate was observed during the autogenous shrinkage test.
