Book Synopsis The Use of Polystyrene Lightweight Aggregate in Concrete by : Mark G. Wilkinson
Download or read book The Use of Polystyrene Lightweight Aggregate in Concrete written by Mark G. Wilkinson. This book was released on 1992. Available in PDF, EPUB and Kindle. Book excerpt: "Polystyrene lightweight concrete, its potential structural use and non-structural uses in today's society, is a growing importance. This thesis surveys all other forms of lightweight aggregate used in Australia and their uses. Identifies the properties, uses and availability of polystyrene aggregate as presently produced. An investigation was conducted into the strength and density of polystyrene lightweight concrete. This was achieved by following the Building Systems Technology (BST) lightweight concrete manual, and the author designing an optimum mix design. It was found that the polystyrene lightweight concrete did not behave like normal weight concrete. All forms of standard workability tests were invalid. The strength characteristics depended upon the cement content, water/cement ratio and the amount of segregation. The use of polystyrene lightweight concrete is limited to its density. This is because the density is related to its strength." -- Abstract.

Book Synopsis Oil Palm Shell by : Mohammad Abdul Mannan
Download or read book Oil Palm Shell written by Mohammad Abdul Mannan. This book was released on 2017. 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.

Book Synopsis Lightweight Aggregate Concrete by : Satish Chandra
Download or read book Lightweight Aggregate Concrete written by Satish Chandra. This book was released on 2002-10-28. 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.
