Oil Palm Shell


Book Description

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.




Recycled Aggregate in Concrete


Book Description

Concrete is the most used man-made material in the world since its invention. The widespread use of this material has led to continuous developments such as ultra-high strength concrete and self-compacting concrete. Recycled Aggregate in Concrete: Use of Industrial, Construction and Demolition Waste focuses on the recent development which the use of various types of recycled waste materials as aggregate in the production of various types of concrete. By drawing together information and data from various fields and sources, Recycled Aggregate in Concrete: Use of Industrial, Construction and Demolition Waste provides full coverage of this subject. Divided into two parts, a compilation of varied literature data related to the use of various types of industrial waste as aggregates in concrete is followed by a discussion of the use of construction and demolition waste as aggregate in concrete. The properties of the aggregates and their effect on various concrete properties are presented, and the quantitative procedure to estimate the properties of concrete containing construction and demolition waste as aggregates is explained. Current codes and practices developed in various countries to use construction and demolition waste as aggregates in concrete and issues related to the sustainability of cement and concrete production are also discussed. The comprehensive information presented in Recycled Aggregate in Concrete: Use of Industrial, Construction and Demolition Waste will be helpful to graduate students, researchers and concrete technologists. The collected data will also be an essential reference for practicing engineers who face problems concerning the use of these materials in concrete production.




Feldspar Minerals


Book Description

Remarks by JVS. Volumes 1 and 2 of Feldspar Minerals were published in 1974, but Volume 3 was not completed because I was forced to devote 3 years to the resolution of unforeseen problems in the construction of an ion probe. By 1977, the incomplete draft for Volume 3 had become obsolete because of the enormous advances in knowledge of feldspars, particularly those in lunar rocks and meteorites, and in both deep-seated and ancient terrestrial rocks. Furthermore, it soon became obvious that a completely new version of Feldspar Minerals was needed because of the important new results on the physical and chemical properties. I had kept up with the interesting but tedious chore of weekly reading of the incoming literature and maintenance of the files. By 1980, the intense day-to day pressure had gone from my research programs on lunar rocks and on the development of the ion microprobe as a quantitative geochemical instrument, and I began preparation of a second edition of Feldspar Minerals.

Lightweight Aggregate Concrete


Book Description

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.




Waste Materials and By-Products in Concrete


Book Description

The amount and variety of waste that humanity dumps in landfill sites is nothing short of a scandal, believes Rafat Siddique, of Deemed University in Patiala, India. Instead, we ought to be building new homes out of it! Siddique shows in this important book that many non-hazardous waste materials and by-products which are landfilled, can in fact be used in making concrete and similar construction materials.
